The Only 50 Sailing Terms You'll Need To Know (With Pictures)

Ever get confused by all those odd sailing terms? Starboard, tack, jib… Well, no worries. In this article, I'll go over the most important sailing terms for beginners.

This is a great resource for beginning sailors that need an overview of the most important sailing terms without drowning in it . For a comprehensive list, check out this Wikipedia glossary of nautical terms . There are A LOT of nautical terms there. But no one in his or her right mind will read through that entire page (it has 48.434 words!). There are a lot of obscure words listed that no one really uses anyways. So in this article, I've filtered out the most important ones to get you up to speed quickly. I've also added pictures so you'll know what we're talking about.

Let's jump straight in. For the sake of good manners, I have categorized them by topic. If you are looking for a specific term, just ctrl+f your way directly to it.

Here are the only 50 sailing terms you'll need to know:

terms on a sailboat

Orientation

Parts of the boat, parts related to sails, other terms.

...because it isn't as easy as 'left', 'right', 'front' and 'back'. No, no.

Port is the left side of the boat. It's as simple as that. I'm not entirely sure why don't they just call it 'left' these days. The name came to existence because centuries ago, you always docked your big boat with the harbor (port) being on the left side. And the word stuck with us till today.

terms on a sailboat

Starboard is the right side of the boat. If in a car, you say 'look to your right', on a boat, you say 'look to the starboard'. Again, you might as well just call it 'right'. Oh, wait… you wouldn't seem as cool if you did. Alright, let's keep calling it starboard.

terms on a sailboat

The bow is the front of the boat. The word likely comes from the Middle Dutch 'boech' (nowadays spelled 'boeg'). If you call it 'front' instead, you will get your message across just as well. But it won't get you the admiring looks from those around you.

terms on a sailboat

Stern is the back of the boat. That is where you, as a captain, will spend most of your time. Whether you will force your crew to call it 'stern' or let them use the word 'back', like the dry land creatures they are, is up to you. After all, you are the captain.

terms on a sailboat

The windward side of the boat is the side facing into the wind. So if the wind is coming from the right side, the windward side is on the right. Unlike some of the previous ones, this term actually makes sense - at times you need to talk about a direction not fixed in relation to the boat, but rather relative to the direction of the wind.

terms on a sailboat

Leeward side of the boat is the lee side. If the wind is coming from the right side, the leeward side is on the left. Note that neither windward nor leeward specify the angle of the wind. Thus even if the wind was coming 20 degrees right off of the direction of the boat, so almost from the front, left would still be considered the leeward side.

terms on a sailboat

Since there are gadgets and parts on the boat that you won't see anywhere else, it only makes sense they all have their own special name. You want to know these because unlike the direction terms where you can do with 'left' and 'right', you don't want to call a tiller 'that stick thing back there'.

Helm is the boat's steering wheel. In this case, I forgive those who came up with this name, since it is shorter than 'steering wheel' and thus saves valuable time that we can spend on sailing. Though I doubt linguistic economy was the reason.

terms on a sailboat

Tiller is the long stick that operates your boat's rudder. A steering stick, if you will. It has the same function as a helm does, but it is usually used on smaller boats, where a helm would take up too much space. Or by people who prefer it to a helm, since a tiller offers a bit more in terms of response.

terms on a sailboat

The rudder is the long, flat piece of metal or wood that sits underwater below the back of your boat. Connected to a tiller or a helm, it is used to control the direction of your exciting voyage. By the way, since aerodynamics and hydrodynamics work in similar ways, a plane is also operated by a rudder. Though that one isn't underwater. Hopefully.

terms on a sailboat

Hull is the boat's body. Whatever the shape or size, whether opened on top (like a dinghy) or closed by a deck, (like a traditional sailboat) it's all called a hull. Structures sitting on top of the deck, like a deck salon or cabins, aren't considered a part of the hull anymore.

terms on a sailboat

The keel is an underwater fin below the boat's belly. The sizes and shapes vary, sometimes it is relatively short and goes deep, (fin keel) sometimes it runs from the front all the way to the back (full keel or ballast keel). It is there mainly for stability and to help maintain forward direction when sailing.

terms on a sailboat

The cockpit is the area where a boat is operated from. On sailboats, it is usually in the back and it is an open area without a roof, though this varies. You will find the rudder control and winches there. In 'smaller' (below 70 ft or so) sailboats this area oftentimes doubles as a deck dining place with a table and seating.

terms on a sailboat

The bimini is a sun roof or shade that is covers the cockpit, and is generally attached to a steel frame which runs over the cockpit.

This is where things tend to get confusing. There are a whole lot of parts and a whole lot of names for them. It pays off for you and your crew to know them though, as during the stormier moments, you all want to be on the same boat (ha, ha) linguistically, as every second counts.

Lines are ropes. Not much more to add here. I suppose a 'line' sounds a bit fancier than a 'rope'. One thing this article will teach you is that if there is the slightest crack in the wall of your boat, linguistic elitism will leak its way in.

terms on a sailboat

This one is quite self-explanatory. The mainsail is the main, largest sail of the boat, attached to the mast on the side and the boom at the bottom. It has a triangular shape and serves as the most important sail, the first one you should get acquainted with if you are just starting out.

terms on a sailboat

The jib is the front sail of your boat, sometimes also called the genoa. That is as long as you are sailing on the traditional sloop - the classical two sail setup you see the most often. The jib is wrapped around the line that goes from the top of your mast to the boat's bow.

terms on a sailboat

Spinnaker is the third type of sail you are the most likely to encounter on your travels. It goes in front of your boat and has a half balloon or kite-like shape. This is because it is constructed specifically for sailing downwind. Its purpose is to grab as much backwind as it can and drag your boat forward. It is not attached to the boat most of the time like the mainsail or the jib, instead, it is stored separately and used only when needed.

terms on a sailboat

The mast is the tall, vertical pole that goes from the floor of your salon, through the deck, meters above your boat. All the sails are attached to it, also radars and lights, giving sailboats radio and visual visibility far greater than that of equally sized motorboats. Take that, ya noisy stinkies!

terms on a sailboat

The boom is the horizontal pole right above the deck, attached to the mast at the right angle. The bottom of the mainsail is attached to it, it is used to determine its shape and direction. It is also where the mainsail is often stored, folded and covered with a protective sheet. The boom is also among the top causes of injuries on a sailboat, as in certain winds it tends to swing with force powerful enough to knock a few grown men overboard. Stay away from its reach at all times when under sail.

terms on a sailboat

The forestay is the cable going from the top of the mast to the very front of the bow. It is there to hold the mast in place. Sometimes you will find people refer to it as the 'headstay'. It is often made of steel, so it is safe to hold on to it when you are pretending to be Jack on the bow of the Titanic's, the boat hits a wave and you lose your balance.

This diagram is from our guide on sailboat parts , which I really recommend for beginners. It walks you through all the most important sailboat parts in normal words.

The backstay is the cable going from the top of the mast to the very back of the boat. In many cases it is doubled at the bottom, each end attached to one corner of the back of the boat so that they don't interfere with space and provide more stability for the mast. Just as with forestay, these are made of steel.

Shrouds are the cables going from the top of the mast to the left and right side of the boat. Sometimes there are four, two on each side. Together with forestay and backstay, they make sure your mast withstands all the forces exerted on it when the wind pushes the sails.

The foot of a sail is its bottom edge. If you imagine a sail as a triangle, the base is called the foot. You probably won't use this term while sailing, but when researching proper sail trim, it is likely you will stumble upon it.

terms on a sailboat

This diagram is again from our guide on sailboat parts , which I really recommend for beginners. If you're looking for a good starting point to learn your sailboat ins and outs, this article is perfect for you.

Leech of a sail is its back side edge. Thus it is the part closest to you when you are standing at the helm. Just as with the foot, this is a term quite often used when describing sail trimming techniques, since the shape of the leech determines the shape of the whole sail.

Luff of a sail is its front side edge. Thus the part the furthest from you when you are standing at the helm. For mainsail, it is the edge that is right next to the mast, for the foresail it is the edge right next to the forestay. Just as with foot and leech, the shape of these edges determines the overall shape of the sail so you will most likely encounter these terms in trimming lessons and tutorials.

The head of a sail is its top corner. On a traditional sloop, you will have the 'main head' and the 'jib head'. There is usually a reinforcing patch of some kind on these corners, as you will find a hole in them to which a line is attached.

It's also something else entirely, but more on that later ...

Halyard is the line attached to the sail head. On your boat, you will most likely have two. The 'main halyard' which is what you use to hoist your mainsail if it is folded on the boom, and the 'jib halyard' which holds the jib head up.

terms on a sailboat

Clew of a sail is its back corner. The line attached to the 'main clew' will be used to hoist your mainsail if it is wrapped inside of the mast. The line attached to the 'jib clew' will be used to open the jib on most sailboats since jibs are most often wrapped around the luff.

Telltales are light, usually cotton or wool pieces of ropes attached to a sail, showing you the airflow around it. These are important because they help you determine if your trim is effective or not. Because of the material they are made of, you might sometimes encounter them being called 'woolies'.

Vang, or a 'boom vang' is a device pulling the boom down. This is important because it controls the tension of the mainsail, influencing its shape greatly. You won't find it on every boat though. Holiday cruisers often don't have it, as it is a piece of equipment focused on performance and thus not necessary for your average trip.

terms on a sailboat

Topping Lift

The topping lift is a line that is attached to the aft (back) end of the boom and runs to the top of the mast. It supports the boom whenever you take down the mainsail.

Also referred to as a 'horse', the traveler is a side to side track to which the boom is attached, allowing the control of the extent to which the boom goes off the centerline. This is important especially if the wind is blowing from behind and you need to control the angle of the mainsheet.

terms on a sailboat

Outhaul is the line attached to the mainsail or the jib clew, allowing the control of the foot tension. This is important for determining the sail shape - for instance in stronger winds, you want the foot to be more tense to achieve a more effective airflow as opposed to slower winds where you can allow the foot to arch more.

terms on a sailboat

Reefing is reducing the sail area to lessen the power exerted on it by the wind. You may want to reef if the wind is getting too strong for your boat, or if it is changing too rapidly, as an overpowered boat is difficult to control. Fun fact: they say that when you feel you need to reef because the wind got too strong, it is already too late to reef.

terms on a sailboat

A batten is a slat placed horizontally in the body of the sail to support its shape. You will not find them on all sailboats, it is a performance-enhancing element that many cruisers lack. It helps tremendously as without it, sails tend to belly out and lose their shape under certain conditions.

The cleat is a piece of fitting where a line can be secured and immobilized, even if under great tension. It usually consists of two cogwheel-like pieces fastened close to each other, in the middle of which the rope is placed, unable to move thanks to friction. This type is great as it allows for a quick release. Sometimes though, it is a simple piece of metal or plastic where the rope is tied.

...and then there are all those things that just float around you when sailing, those little things that are the reason for you having to carry a dictionary in your pocket.

Fenders are bumpers allowing some contact with other boats or piers while docked, without scraping the paint. They are often balloon-shaped, made of rubber or some relatively soft material. They are usually attached to the boat's railing and you move them around as you need.

terms on a sailboat

The beam is the width of the boat. Could be just called width, I know. The word comes from the fact that there are transverse reinforcing beams in the boat hull and deck. Next time you are choosing your charter boat for holidays, you will know what this attribute means.

True wind is the actual direction and speed of the wind. This is different than the apparent wind, which is wind direction and speed relative to the boat. Apparent wind is a combination of the true wind and the headwind, which is the wind the boat experiences solely by being in motion.

The berth is a sleeping space on a boat. Thus if a boat has eight berths, it means eight people can comfortably sleep on it. Note that this often includes the salon couches, so a berth is not necessarily a space in an actual bed for one person.

terms on a sailboat

Boat's draft is the distance from the water surface to the deepest point of the boat. In other words, the draft is the minimum water depth you can go to and not scrape your hull or keel. Better double this number when sailing, just to be safe, as hitting the seabed can have disastrous consequences.

Tacking is zig-zagging towards your destination. It is necessary in case your destination is in the direction of the wind since sailboats can not go directly into it. Since the closest to the wind direction you can sail is around 45 degrees, you have to change direction left and right from your desired course.

This diagram is from our guide on sailing into the wind for beginners , which explains in 7 simple steps how to get good upwind sailing performance.

Bareboat is a boat without a skipper. You will encounter this term in boat charters and it means you rent the boat without any crew, thus you need to operate it yourself. It is the best way to sail unless you enjoy living in close proximity to a sea wolf who you also have to feed.

The chart is a nautical map. It differs from classical maps as it depicts information relevant for a sailor - water depth, navigational hazards, seabed material, anchorages and so on. Formerly made of paper, these days made of ones and zeros. As is everything in this digital world.

terms on a sailboat

We have a guide that explains all the different chart types clearly for beginners - read it here .

Galley on a boat is its kitchen. Also a medieval warship, but if you find this term in a boat's description, war is not likely what they have in mind.

terms on a sailboat

Heads on a boat is the bathroom. Though in all my years of sailing I have never ever heard anybody use this term instead of a 'bathroom'. I suppose saying that you are going to use the heads just sounds odd.

terms on a sailboat

A knot is the unit of speed of boats. It is equal to one nautical mile per hour. That is 1.852 kilometers per hour or 1.5078 miles per hour. Though a bit confusing and annoying at times, you will have to get used to this, since most of your boat's instruments will use this unit. It dates all the way back to the seventeenth century when boat's speed was measured with a rope with knots tied on it.

terms on a sailboat

Mooring is attaching the boat to a buoy that is anchored to the seabed. This is usually a cheaper option to docking in a marina. It also means larger space between the boats anchored in the same area, thus more privacy. Though you will have to use your dinghy to get to shore instead of just stepping on the pier directly from your deck.

terms on a sailboat

A salon on a boat is its living room. On smaller boats, it is usually in the same room as the boat's kitchen and the captain's corner with navigation instruments.

terms on a sailboat

A skipper is the captain of a sailboat. If you ask me, the word 'captain' is much better than a skipper, which to me sounds like a small boy who sits on the shore the whole day, skipping stones. But hey, who am I to talk.

terms on a sailboat

A monohull is a classical boat with a single hull. A boat with two hulls is called a catamaran, or a 'cat'. Although rare, there are also trimarans, boats with three hulls. Multihulls with four or more hulls do happen but they are an unnecessary freak of nature.

terms on a sailboat

So there you have it. Fifty sailing terms you will encounter the most when traveling or learning. I know you might think some of them are a bit unnecessary since they have a perfectly fine 'real world' equivalent. I agree. But until the tradition changes, you might want to get some of these under your skin.

A boat's freeboard is the distance from the upper deck to the waterline. Classic yachts have low freeboards, so they appear to lay deeper in the water, as opposed to more modern yachts, which have a higher freeboard. It literally means 'free-board' : the amount of visible board.

The lunch hook is a light anchor setup that is used to moor small yachts temporarily. It typically uses a lightweight anchor on a short scope that takes little effort to set. The lunch hook is only used when the crew is on board and will be monitoring the anchor.

In naval architecture and ship design: “Head” = WC = Bathroom. A toilet is still a toilet. The toilet is in the head. In olden day, the toilet was a hole in the head.

Hi Rich, you’re absolutely right. I’ve corrected the error. Thanks for pointing it out.

A nautical mile is one minute of a degree, so if you travel 60 nautical miles that means you have gone 1 degree around the “globe”. (Note: arc length not actual length.) This is the original definition. As such the average was agreed upon and the lengths given a standardization. Which you mentioned.

As such 1 knot is to travel one nautical mile in an hour.

Also 1.5078. I think you made a mistake as it should be 1.1508 miles to a nautical mile.

Thanks for the information. Sorry about being a pedantic mathematics teacher.

So, where is the “nautical mile” calculated from, the equator or one of the tropic lines?

Just to clarify a nautical mile. If you draw an imaginary line from the North Pole or South Pole to the center of the Earth and draw another line from the center of the Earth to any point on the equator, it forms a right angle, which is 90 degrees. This equates to latitude. The equator is 0 degrees and the poles are 90 degrees. Your latitude is the angle that you are north or south of the equator. Each degree of latitude is divided into 60 minutes. A minute of latitude is the same distance matter where you are on Earth. It is 6,076 feet. This is the length of a nautical mile. A statute mile is 5,280 feet, so a nautical mile is 1.1508 statute miles.

Thank you very clear and well explained. Hopefully I’ll remember The Fifty

KöhnSharkösz

Really? No gunwale? No transom? Those or basic terms to the Washington State Boater Education Card required to operate watercraft here. Definitely more of a “need to know” than bimini.

Thank you, those definitions and explanations were clear, thorough, and helpful. I’m really glad I found my way (somehow) to your webpage.

Sailing Terms: A Complete Guide

Sailing Terms: A Complete Guide | Life of Sailing

Last Updated by

Learning sailing terms when you first get into boating can be a daunting task.

Some sailing terms are logical, like 'fore' means forward or front of the boat, while others might as well be in a different language. Athwartship, for example. Nothing in our daily lexicon gives any clues as to what that might mean. Like it or not, it's time to dust off the old noodle and get to memorizing some new vocab words!

Knowing the difference between a clew and a tack, a luff and a leech, will help you communicate with your sail maker regarding which part of your sail needs resewn. If you need to have your rigging adjusted, you must know the difference between your shrouds and your stays, your standing rigging vs. your running rigging.

By educating yourself in the correct names of all parts of your sailboat, you can avoid situations in which you may need to use terms such as ‘thingy’ or ‘that round part at the end of that thing’. While even the most seasoned sailor occasionally troops over the vernacular, it is always beneficial to have as wide a nautical vocabulary as possible. Many in the sailing community get by without knowing the entire sailing dictionary, but if you’re interested in avoiding vocabulary embarrassment, check out the list I’ve compiled of sailing terms that every sailor ought to know.

I’ve been sailing on and off throughout my life and I know from experience that it is incredibly helpful to know the correct terms for each part of your sails, rigging, and boat.

Sailors are among the kindest, most helpful people you’ll ever meet. But, if you’re looking for help on why you’re not getting the most speed out of your mainsail and you know don’t know the correct terms for each part of the sail, it may be hard to get advice from you fellow sailor on why ‘the back of the mainsail is flappy’. They would be more likely to give useful advice if you’re able to tell them that you’re struggling to keep wind in the roach of your mainsail. Check out my list of sailing terms and see if a few don’t stick. I’ve done my best to include pictures when possible.

Table of contents

Sailing Terms

Abeam : When an object, craft or island is abeam your vessel, that means that it is off the side of your boat. It is 90 degrees from the centerline of your boat.

Abaft : Toward the stern. “Honey, have you seen my boat shoes?” “They’re abaft the navigation table!” This is the opposite of forward.

Aft : In the stern of the boat. For example, the back cabin is referred to as the aft cabin.

Apparent wind : The wind direction and speed which the crew observes to be blowing in combination with the true wind. This is often different from the true wind direction and speed due to the boat's motion.

Astern : The area behind the boat. If you go astern, you are going in reverse.

Athwartship : Directionally perpendicular to the centerline of the boat.

Backing (a sail) : Forcing the sail to take wind into its opposite side by pulling the sail to the opposite side of the boat.

Backstay : The wire that runs from the back of the boat to the mast head. This prevents the mast from falling forward.

Bailer : Any scoop-like container that is used to remove water from within a vessel’s hull.

Ballast : Weight which adds stability to the vessel. The weight usually is composed of lead or iron and placed low in the boat's hull, such as within the keel.

Batten : a thin, flexible strip (often fiberglass) that is inserted into the main sail to help it stay open to the wind. The batten runs from the back edge of the sail (leech) toward the front edge (luff).

Beam : The width of the vessel at its widest point.

Beam reach : Sailing with the wind blowing perpendicular to the direction the boat is traveling.

Bearing off or Bearing away : Steering the boat away from the direction in which the wind is blowing.

Bend : a knot which connects two ropes.

Berth : A slip, a mooring, or a bed within the boat.

Bight : A bend or loop in a rope. When a rope forms a bight, it has changed direction 180 degrees.

Bilge : The lowest area within a boats hull. This area collects water which is then pumped overboard by a bilge pump.

Bimini : The covering over the cockpit. Usually constructed from a stainless steel frame covered with canvas or fiberglass. It provides protection from sun and rain, but not wind.

Binnacle : The pedestal centrally located in the cockpit that generally holds the steering wheel and navigational instruments.

Block : A pulley.

Boom : This pole runs perpendicular to the mast and holds the bottom of the mainsail in place. Its position is adjustable side to side as needed for the wind direction.

Boom vang : A tackle which ensures that the boom does not lift upward from wind pressure in the mainsail.

Boot Top or Boot Stripe : The stripe of tape or paint between the boat's underwater (bottom) paint and it’s above water (topside) paint.

Bow : Front end of the boat

Bowsprit : The forward most protruding pole or platform which some boats possess. This spar allows for the sails and rigging to be attached further forward.

Broach : When a boat sailing downwind accidentally ends up sideways to the waves and heels over dangerously. This can be caused by large seas or poor steering.

Broad reach : Sailing with the wind coming off your stern quarter. If you’re standing at the helm facing the bow, the wind is blowing halfway between the side and the back of the boat.

Bulkhead : The walls in a boat which run athwartship, or perpendicular to the centerline of the vessel.

Capsize : When a vessel tips over past 90 degrees.

Catamaran : A vessel with two hulls.

Centerboard : A retractable keel which helps the sailboat maintain course and stability underway. When raised, the vessel is able to enter shallow waters.

Centerline : An imaginary line that runs from the center of the bow to the center of the stern.

Chainplate : A metal plate that is secured to the boat's hull to which wires supporting the mast are attached. The chainplates may be exterior or interior, visible or hidden.

Chandlery : A store that sells boat supplies and parts.

Cleats : The wooden or metal piece to which ropes are secured.

Chock : A fitting that a line passes through to change direction without chafing.

Clew : The lower back corner of a sail. This is where the foot and leech of the sail meet.

Close-hauled : Sailing as close to the direction the wind is coming from as possible with the sails pulled in tight. (See Points of Sail for infographic.)

Close Reach : Sailing between close hauled and beam reach. (See Points of Sail for infographic.)

Coamings : The lip around a hatch or window which stops water from entering. Also the raised area around the cockpit to keep out water.

Cockpit : The area from which steering occurs. This can be in the center of the boat or in the back of the boat.

Companionway : The doorway into the cabin.

Cotter pin : a bendable metal pin which is inserted into a metal rod then bent to lock it in place.

Daybeacons : Markers for navigation which are on posts. These are red or green.

Dead run : Sailing with the wind coming from directly behind the boat. Sails are fully out to catch the wind.

Dead reckoning : Determining a vessel's position by knowing the direction and speed traveled.

Dinghy : A small boat which is used to travel to shore from the main vessel. This can be propelled oars or a motor.

Dodger : The structure at the front of the cockpit which protects the cockpit and companionway from wind and spray. This is generally made of stainless steel frame covered with canvas and plastic windows. It can also be a solid structure with solid windows.

Dismasting : When the mast breaks off the boat. This can occur due to rigging failure or structural failure of the mast.

Displacement : The weight of the water that would otherwise be in the place of the boats hull.

Drogue : A sea anchor which is deployed to help control the drift of a vessel. It can be constructed like a parachute, bucket, or even a rope dragging behind the boat.

Ebb tide : After high tide when the water is receding towards low tide.

EPIRB : Stands for Emergency Position Indicating Radio Beacon. This device transmits a distress signal to emergency services and notifies them of a vessel's location.

Fairlead: A fitting which encloses a line within a smooth ring and helps guide its direction.

Fathom : A measurement of water depth equal to 6 feet.

Fid : A pointed tool used when splicing a line.

Fiddle : The raised edge around a table which prevents objects from falling off as the boat rocks or heels.

Fix : Determining a vessel's location by using the compass bearing of two or more fixed points of reference such as landmarks or buoys.

Fin keel : A fixed, ballasted keel which is centrally located beneath the hull. It does not run the full length of the hull.

Flogging : When a sail flaps noisily because it is not being filled by the wind.

Flood tide : Time period between low tide and high tide when the water is rising.

Foot : The bottom edge of a sail.

Fore : At or near the bow of a vessel.

Forestay : The wire which leads from the bow to the top of the mast. The forward most sail attaches to the forestay either directly or by use of a roller furling system.

Full keel : A fixed, ballasted keel which runs the full length of the hull.

Furling system : A system around which the sail wraps when not in use and is unwrapped for sailing. This may be around the forestay or within the mast.

Freeboard : The distance on a vessel from the waterline to the deck.

Galley : The kitchen on a boat.

Gelcoat : A colored resin which is painted onto the outside surface of a boat and forms a protective glossy layer.

Genoa : A large forward sail which, when fully extended, comes back past the mast. Larger than a jib sail.

Gimbals : Often attached to a boat's stove, it is the fitting which allows an object to maintain an upright position when a vessel heels.

Gooseneck : The point at which the boom attaches to the mast. It allows the boom to move in all directions.

Ground tackle : The anchor, chain, and line used to fix a boat to the bottom when anchoring.

Gunwale : Pronounced “gunnel”. This is the top edge of a boat's hull.

Halyard : The line which attaches to a sail to raise it.

Hanks : The clips that attach the front edge (luff) of a sail to the forestay.

Hatch : An opening window in the cabin roof much like a skylight.

Head : Bathroom on a boat. Also, the uppermost corner on a sail.

Headway : The forward motion of a vessel through the water.

Heave to : A method of controlling a boat’s position to the waves and limiting headway by backwinding the forward sail and keeping the rudder hard over into the wind.

Heel : The tilt that occurs to a boat's hull when the sails are filled with wind.

In-Irons : When a sailboat is bow into the wind with sails flapping. No steerage is possible as the vessel has no forward motion. (See Points of Sail for infographic.)

Jackline or Jackstay : Lines that are run from the bow to the stern. To these safety lines, sailors attach a lanyard connected to their harness so that they may work on deck without fear of being swept overboard in rough seas.

Jib : A triangular forward sail.

Jib sheets : Lines used to control the jib.

Jibing : Pronounced with a long i sound. Steering the boat from one downwind direction to another downwind direction by turning the stern of the boat through the wind. This will cause the sails to move across the boat to the other side, i.e. from port to starboard.

Kedge anchor : A small, lighter second anchor.

Keel : The bottom most part of a boat's structure. This part provides ballast and stability.

Ketch : A sailboat with two masts. The forward mast is the taller mast.

Knot : Regarding speed, one knot is equal to one nautical mile per hour.

  • Ease – to adjust sails outward or away from the centerline of a boat.
  • Halyard – the line used to raise a sail whether a mainsail or a headsail.
  • Headsail – a sail that is forward of the mast. It can be a genoa, a jib, a staysail or a small storm sail.
  • In irons – technically a point of sail when you’re head-to-wind meaning the bow is pointing directly into the true wind and the boat is unable to maneuver.
  • Jibing (also spelled gybing) – changing direction where the stern swings through the eye of the wind.
  • Leeward – the direction away from where the wind is blowing.
  • Mainsail – the primary sail on a boat which is usually attached in some way to the mast and boom. On most sailboats it’s the primary source of power.
  • Mast – the vertical pole that supports the sails. The mast itself is supported by the rigging.
  • Points of sail – the boat’s direction under sail relative to the true wind . The points of sail are: close-hauled, close reach, beam reach, broad reach and dead run.
  • Reefing – shortening or reducing the area of a sail to de-power a sailboat usually used in a strong wind.
  • Sheet – the line that controls the angle of a sail. There are mainsheets, jib/genoa sheets and others.
  • Shroud – a part of the boat’s rigging that supports the mast from side-to-side
  • Stay – a part of the boat’s rigging that supports the mast fore and aft.
  • Tacking – changing direction under sail where the bow swings through the eye of the wind.
  • Trim – to adjust sails inward or closer to the centerline of a boat.
  • True wind – the actual wind that is blowing – both direction and speed.

  • Mast The tall, vertical pole that supports the sails and allows you to catch the wind and move through the water.
  • Boom The horizontal pole extending off the bottom of the mast that holds the bottom edge of the mainsail.
  • Mainsail The large, triangular-shaped sail attached to the mast and boom that captures the wind’s power to propel the boat forward.
  • Jib The smaller, triangular-shaped sail attached to the bow that helps to steer the boat and balance the force of the mainsail.
  • Rigging The network of ropes and cables that hold the mast and sails in place and help control their movement.

Sail Terminology

Understanding the terminology associated with sails is critical to becoming a successful sailor. Here are 12 of the most important sail terms you should know, along with brief explanations for each:

Basic Sailing Terminology

  • Luff The forward edge of a sail that is attached to the mast, allowing you to adjust the sail’s shape and angle to catch more wind.
  • Leech The aft edge of a sail that is attached to the boom, which helps to control the sail’s shape and release the wind as needed.
  • Foot The lower edge of a sail that is attached to the boom, which helps to control the sail’s shape and power.
  • Head The top of a sail that is attached to the mast and controls the sail’s overall shape and angle.
  • Battens The long, thin strips inserted into the pockets of a sail to help maintain its shape and stiffness.
  • Clew The bottom corner of a sail that is attached to the boom or sheet, which helps to control the sail’s shape and power.
  • Tack The bottom forward corner of a sail that is attached to the boat or a line, which helps to control the sail’s shape and power.
  • Sail Area The total area of a sail, which is measured in square feet or meters.
  • Sail Draft The curve or depth of a sail, which affects its performance and power.
  • Sail Shape The overall form and contour of a sail, which is critical for catching the wind effectively.
  • Reefing The process of reducing the sail area by partially lowering or folding the sail, which can be necessary in strong winds or heavy seas.
  • Furling The process of rolling or folding a sail to reduce its size or stow it away, which is often used when entering or leaving port or in rough conditions.

Wind Direction and Sail Positioning

Understanding wind direction and sail positioning is crucial for successful sailing. Here are the key terms you need to know:

Types of Wind

Basic Sailing Terminology

  • Apparent Wind The wind that is felt on the boat, which is a combination of the true wind and the wind generated by the boat’s movement.
  • True Wind The actual direction and strength of the wind.

Points of Sail

You can find a detailed explanation of the points of sail here

Basic Sailing Terminology

  • Close-Hauled Sailing as close to the wind as possible, with the sail set at a sharp angle to the boat.
  • Beam Reach Sailing perpendicular to the wind, with the sail set at a right angle to the boat.
  • Broad Reach Sailing with the wind at a diagonal angle behind the boat, with the sail angled away from the boat.
  • Running Sailing directly downwind, with the sail on one side of the boat.

Other Terms

Basic Sailing Terminology

  • Windward The side of the boat that is facing the wind.
  • Leeward The side of the boat that is sheltered from the wind.
  • Sail Trim Adjusting the sail and rigging to maximize the power and efficiency of the sailboat.

Navigation Terminology

Navigating a sailboat requires an understanding of a variety of nautical terms. Here are some of the most important terms you should know:

  • Starboard Side The right side of a boat
  • Port Side The left side of a boat
  • Compass A device used for determining the boat’s heading or direction.
  • Bearing The direction from the boat to a specific point on land or water.
  • Chart A map or nautical publication that displays water depths, navigational aids, and other important information for safe navigation.
  • Latitude The angular distance between the equator and a point on the earth’s surface, measured in degrees, minutes, and seconds.
  • Longitude The angular distance between the prime meridian and a point on the earth’s surface, measured in degrees, minutes, and seconds.
  • Course The direction in which the boat is traveling.
  • Plotting The process of marking a course on a chart or map.
  • Waypoint A specific point on a navigational chart or map that serves as a reference point for plotting a course.

Basic Sailing Terminology

  • Tacking This maneuver involves turning the bow of the boat through the wind in order to change direction. To tack , the sailor will turn the helm towards the wind until the sails begin to luff, then quickly steer the boat in the opposite direction while adjusting the sails to catch the wind on the new tack.
  • Jibing This maneuver is similar to tacking, but involves turning the stern of the boat through the wind. To jibe, the sailor will steer the boat downwind until the sails begin to luff, then quickly turn the stern of the boat in the opposite direction while adjusting the sails to catch the wind on the new tack.
  • Heading up This maneuver involves turning the boat closer to the wind in order to sail upwind. To head up, the sailor will turn the helm towards the wind while simultaneously trimming the sails in to maintain speed and prevent the boat from stalling.
  • Falling off This maneuver involves turning the boat away from the wind in order to sail downwind. To fall off, the sailor will steer the helm away from the wind while simultaneously easing the sails out to catch more wind and accelerate the boat.
  • Docking This maneuver involves bringing the boat alongside a dock or other fixed object in order to moor or disembark. To dock, the sailor will typically approach the dock at a slow speed while using lines and fenders to control the boat’s position and prevent damage.

Knots and Lines

Learning the right knots and lines to use is essential for any sailor. Here are some of the most important knots and lines to know:

Basic Sailing Terminology

  • Bowline This is a versatile knot used for many purposes, including attaching a line to a fixed object, such as a mooring or cleat.
  • Square Knot A simple knot used to join two lines of the same diameter.
  • Clove Hitch A quick and easy knot for attaching a line to a post or piling.
  • Figure-Eight Knot A knot used to stop the end of a line from unraveling.
  • Cleat Hitch A knot used to secure a line to a cleat.
  • Sheet Bend A knot used to join two lines of different diameters.

  • Jib Sheet A line used to control the angle of the jib.
  • Mainsheet A line used to control the angle of the mainsail.
  • Jib Furling Line A line used to furl the jib.

Sailing Safety

  • Personal Flotation Devices (PFDs) These are the life jackets or vests that you must wear when on board to ensure your safety. Choose a PFD that fits you properly and is appropriate for your body weight.
  • Tethers and Harnesses These are designed to keep you attached to the boat and prevent you from falling overboard. Make sure to clip yourself onto the boat when you’re on deck or going up to the mast.
  • Man Overboard ( MOB ) Drill This is a critical safety procedure to practice with your crew. Learn how to quickly identify and recover someone who has fallen overboard.
  • Emergency Position Indicating Radio Beacon (EPIRB) An EPIRB sends a distress signal and your location to rescue services in an emergency. Make sure it’s properly registered and in good working condition.
  • Navigational Lights Ensure your boat has the required navigational lights and know how to use them properly. These lights help other boats see you in low-light conditions.

Remember that safety is always the top priority when sailing, and it’s essential to take it seriously.

In order to become a true sailor, you’ll first need to learn some essential sailing terms. Luckily, we’ve got you covered! In this A-Z of yachting terms, we’ll briefly explain yacht terms, parts, equipment, sailing commands, and even some pirate jargon.

For you to understand the ins and outs of a boat you should know where it starts and where it ends. The front of a boat is known as the bow while the back is called the stern. Also, while the left of the boat is called the port side, the right is called starboard. Now that you’re familiar with the different sides of a boat, let's get down to real sailing business. 

  • ABANDON SHIP! – You have probably heard this in movies and you know it doesn't bring any good. You should leave the vessel immediately as it looks like your ship is in some imminent danger.
  • ABOARD – When you’re aboard, you are on a boat. The opposite of ashore. 
  • ABOVE DECK – Above deck means you are standing on the deck, not above it.
  • ABREAST – We call vessels that are side to side - abreast.
  • ADRIFT – Don't panic but if your vessel is adrift it means it has sailed off without you. Okay, you can panic a little.
  • AGROUND – If the water is not deep enough, then you go aground and your vessel’s bottom touches the ground.
  • AHEAD – This means something is in front of the boat, for example your destination is ahead.
  • AHOY – Another way to say hello, with a little pirate tone.
  • ALL HANDS HOAY – Everyone should get on the deck. 
  • AMIDSHIPS – The middle of a vessel, whether from her length or width.

Glossary: essential terms a sailor should know

  • Glossary: essential terms a sailor should know

We have put together a comprehensive list of essential sailing terms to enhance your nautical knowledge. Delving into diverse areas such as meteorology, navigation, and boat equipment, our glossary covers sail types, boat components, and crucial units of measurement and abbreviations that every sailor should be familiar with. Plus, you'll find terms unique to charter boats, the boat rental process, safety at sea, signalling aids, and modern sailboat technology.

Anchor windlass is a mechanical device used to hoist and lower the anchor and its chain on a boat. It operates under high tension and typically has its own circuit breaker to protect it from electrical overloads. When using an anchor windlass, it is essential to allow for short breaks during operation to prevent it overheating and any resultant damage to the equipment.

Anticyclone is an area of high air pressure.

Apparent wind is the wind we perceive when we are on board and results from the vector sum of the real wind and the wind generated by our motion while sailing. The topic of apparent wind is covered in detail in our article — Apparent vs. true wind .

Autopilot is a device designed to steer a boat along a predetermined course. It independently adjusts the rudder as required, ensuring the vessel follows the set path to its destination as accurately as possible. 

Baby net or safety net is a safety feature that prevents small children from falling off the deck into the water. It is a net similar to a fishing net, which is installed along the boat's railings. A baby net does not come as standard with a rental boat, so always discuss it with the salesperson when booking if you want to order the net from the charter company. We discuss safety features in our article — Sailing with kids: how to keep all of you safe and happy .

children's nets

Safety nets on the boat effectively prevent children from falling into the water.

Barber hauler is a sail control device used to adjust the angle of the jib or genoa sail in relation to the wind, mostly found on more sporty boats. It consists of a line or tackle system attached to the clew of the sail, allowing sailors to fine-tune the sail's position for optimal performance and improved windward efficiency.

Bathing or swim platform , is a foldable structure located at the stern of a boat, providing easy access to the water for swimmers or during training activities. When sailing, it is advised to keep the bathing platform closed and secured in place, rather than left extended.

Batten is the reinforcement in the mainsail. Mainsails are generally classified based on their shape and construction, with variations such as full-batten, partial-batten, or no-batten mainsails.

Beaufort scale  is a widely recognized scale in the sailing world. It categorizes wind forces and their corresponding effects on sea surface conditions, allowing skippers to estimate wind strength visually. By observing the behaviour of the sea surface and the wind's impact on it, sailors can use the Beaufort scale to make informed decisions about their sailing course and speed.

Bearing compass is a type of compass that is used to determine the bearing, or direction, of an object or location relative to the compass itself. It is commonly used in navigation to determine the direction of a distant landmark or to maintain a specific course while sailing.

Bimini  is an alternative term for a sun canopy that provides shade for the helmsman's station and the rear portion of the cockpit. In the rain, it serves as a slight protection from the water. Often, however, sailors fold it up for sailing, and sometimes there is no other way to do it, as the mainsail sheet passes through it.

Bow thruster  is a mechanism located at the bow of a vessel that assists with maneuvering while in port. It is not intended to replace the main engine and should not be used while sailing. The primary function of a bow thruster is to help shift the boat's bow to port or starboard. It's essential to operate the bow thruster with caution, as it has a high voltage. Use short, intermittent presses (2-3 seconds) rather than prolonged holds to prevent the bow thruster from burning out and becoming inoperable.

Bowsprit is a spar that extends from the bow of a sailboat. It is used to attach the forestay, which supports the mast, and to extend the sail area forward. On historic ships it is slightly angled upwards towards the sky. On more modern boats it extends straight out from the bow and may be retractable or foldable to make docking and storage easier.

Brackish water is water that is neither salty like the sea nor fresh like freshwater streams. Its salinity is somewhere in between. It is most often found at the mouths of rivers or in lakes by the sea.

Breeze is a periodic wind phenomenon caused by differences in air temperature between day and night. According to the time when it occurs, it is distinguished between day (sea) and night (land). The breeze is a beautiful sailing breeze. Read more about breezes in our guide — Understanding land and sea breezes: how they can affect your sailing .

Buoy field  is an arrangement of multiple buoys within a bay, anchored to concrete blocks on the seabed. Typically, a fee is charged by the operator for using these buoys, but the cost is generally lower than docking at a pier or marina.

Cardinal marks are navigational aids that indicate the location of safe water relative to a hazard. They are named after the four cardinal points: North, East, South, and West.

Genoa , also known as genoa jib , is a type of sail that is positioned forward of the mast and is used on sailing boats. It typically covers the area from the mast to the bow of the boat, and is larger than the mainsail. It can range in size from 100% to 150% of the foretriangle, which is the triangle formed by the mast, forestay, and deck.

GPS , which stands for Global Positioning System, is a satellite-based navigation system that provides location and time information anywhere on Earth. Sailors can use an electronic GPS device to accurately determine their position on the water.

Gulets are double-masted boats designed and built based on traditional Turkish wooden sailing boats. One of the typical destinations for gulets, which we also offer, is Turkey.

Gybe or jibe is a sailing maneuver where the sailboat's stern is turned through the wind to change the wind direction from one side of the boat to the other, usually while sailing downwind. The boom of the sail swings across the boat during a gybe, and it should be performed carefully to prevent accidents and damage to the boat and crew.

Harness is a safety device used in sailing that is attached to a sailor's body or life jacket and secured to the boat's deck with a buckle to prevent falling overboard.

Halyard  can is a rope used to raise different types of sails such as the mainsail, jib, genoa, spinnaker, and gennaker. Each sail will typically have its own dedicated halyard to hoist it up the mast.

150+ Nautical Terms: Illustrated Guide

Sailing and nautical terms have been refined over centuries, forming a unique glossary that can leave even the most seasoned wordsmiths scratching their heads.

Today, we’ll look at the terminology of words and names used at sea to help you through even the saltiest conversations.

Terms for the components a sailboat consists of

Let’s start with terms for the parts a sailboat is put together from. These refer to each component and explain what they are.

The main parts

Mast : The mast is the big, tall spar that holds up the sails! Some boats have more than one mast.

Mainsail:   The mainsail is the sail behind the mast and on top of the boom. Often just referred to as “the main.”

Boom:  The spar that sticks out behind the mast.

Rudder:  The rudder is also a fin sticking down under the boat but is located back towards the stern and connected to the wheel or tiller, enabling you to steer the vessel.

Headsail:  The sail(s) in front of the mast. Many boats have more than one headsail and can be of different sizes and shapes.

Spreader:  The fins or wings that space the shrouds out from the mast.

Hull:  This is the body or structure of the boat. Monohulls have one hull, catamarans have two hulls, and trimarans have three hulls – you get the point.

Keel : This is the heavy fin sticking down under the middle of the boat, allowing it to sail. There are many different keel designs, but they are all heavy, and their job is to keep the vessel stable and track through the water under sail.

Helm: This is the position where you steer the boat. Usually, this is a wheel, but it can also be a tiller on many vessels.

Cockpit: The cockpit is the boat’s steering position and where you will find the helm.

Transom: The flat surface across the stern of the boat.

Bow and Stern: The bow is the front part of a boat, while the stern is the rear end. 

Midship:  By some called amidships – The center of the boat.

Beam: The widest part of the boat. It is also referred to as the sides on the middle of the vessel.

Waterline: This is the part where the hull (body) of the boat meets the water. Many ships have a painted stripe to mark the waterline, indicating the boat’s load. If you have too much stuff on board, the waterline goes underwater, and it is time to do some housekeeping!

Freeboard: The vertical part of the ship side between the water and the deck.

Deck: The deck is the “floor” of the boat when you are outside. You have probably heard the term “All hands on deck!”

Spar: The general term for a pole made of a solid material like wood or metal used to support a boat’s sail. The mast, boom, spreaders, etc., are defined as spars.

Gooseneck:  This fitting connects the boom to the mast and allows it to move horizontally and vertically.

The standing rigging which holds the sails

Forestay:  The forestay   is a wire that runs from the bow to the top of the mast. Some boats, like the Cutter rig, can have several additional inner forestays in different configurations.

Furling system:  Most sailboats have their headsail on a furling system, a tube running along the forestay from the bottom furler drum to the masthead swivel. 

Backstay/Aft stay:  The wire that runs from the aft of the boat up to the top of the mast.

Shrouds:  On most common cruising boats, there are usually four shrouds on each side to support the mast from sideways motion. The shrouds are generally made of wire but can also be rods or Dyneema lines. The  cap shrouds  run from the masthead through the tips of the spreaders down to the deck. The  intermediate shrouds  run from the lower part of the mast, through the lower spreaders, and to the deck. The  lower shrouds  run from the mast under the lower spreaders down to the deck – one forward and one aft on both sides. This is called  continuous rigging .

Turnbuckle:  The fitting that connects the shrouds to the  chainplate  on the deck. These are adjustable, allowing tensioning of the rig.

Chainplate:  A fixed strong point bolted on the deck. Usually reinforced with a backing plate underneath. 

You can read more about the standing rigging in this article .

The running rigging which operates the sails

Line:  The running rigging on a sailboat often consists of lines, a type of rope with a smooth surface that works well when used on a winch. 

Halyard:  This is the line you use to hoist and lower the sail. 

Sheets:  The sheet is the line you use to  control a sail . The  mainsheet  controls the angle of the mainsail and is attached between the boom and the  mainsheet   traveler . The two headsail sheets are connected to the sail’s clew (lower aft corner) and run back to each side of the cockpit.

Outhaul:  The outhaul is attached to the clew of the mainsail and used to adjust the foot tension. 

Topping lift:  A line attached to the boom’s end runs through the masthead and down to the deck or cockpit. Used to lift and hold the boom and also function as a spare main halyard.

Downhaul:  A line used to lower with. Typically used to lower the mainsail when reefing and lowering the spinnaker and whisker poles.

Reef line:  Depending on your setup, these lines are used to reduce the sail area of the mainsail.

Shaking a reef: When we sail with a reefed sail and want to increase the sail area back to full, we call it shaking the reef.

Equipment used to operate the running rigging

Block:  A pulley with a sheave wheel. These are used to change the direction of a pull on a line or rope and give a mechanical advantage. 

Mainsheet Traveler:  The traveler is a horizontal track attached to the mainsheet through a series of blocks. The traveler enables you to adjust the boom from side to side or lock it at an angle.

Cars:  The cars are pulleys or blocks attached to a track on the side decks that your headsail sheets run through. They are used to control the angle of the sheet between the clew and the deck. 

Jammer:  The jammer is used to lock a line in place. Most sailboats use these for locking the halyards, mainsheet, outhaul, reef lines, traveler lines, boom vang lines, etc. 

Spinnaker Pole:  A spar used to wing out a headsail when sailing off the wind, particularly the Spinnaker. 

Whisker Pole:  Similar to the spinnaker pole, but typically built lighter and attached to a track on the mast. These can be found in fixed lengths or adjustable lengths. 

Boom Vang/Rod Kicker:  A compression pole is used to tension the boom downwards. 

You can read more about the running rigging in this article.

Deck gear and hardware

In-mast furling:  A furling system that furls the mainsail in and out of the mast as opposed to the traditional way where the mainsail is secured to the boom and is hoisted and lowered on a track behind the mast.

In-boom furling:  A furling system that furls the mainsail in and out of the boom. 

Stack Pack:  Also called  Lazy Bag or Lazy Pack . A bag with a zip attached to the boom where the mainsail is stored when unused.

Lazy Jacks:  A set of lines running from the stack pack to the mast guides the mainsail up and down from the Stack Pack and prevents it from falling on the deck. 

Masthead:  Not to be confused with the term masthead rigging. Out of context, the masthead is the top of the mast.

Winch:  A metal drum that gives you a mechanical advantage when tightening lines.

Sprayhood:  The windshield of the boat that protects the people in the cockpit from sea spray. Some ships have canvas spray hoods that can be folded down or removed. Others have solid sprayhoods, often called a  hard dodger  or a  doghouse .

Bimini:  The cockpit’s roof protects you from the elements and provides shelter from spray, rain, and burning sun rays! A bimini can be made of canvas or hard material. The hard bimini is usually called a  hardtop .

Outboard:  Short-term for an outboard engine, which usually belongs to the dinghy.

Cruisers:  What we sailors often call ourselves. Especially those of us living onboard. Although salty, we are definitely handy to have on board as we are also electricians, mechanics, plumbers, and you name it.

Fenders:  Like Captain Ron said in the movie, the rubber bumper things you hang off the side of your boat to prevent it from scratching against something like the key side or another boat. Conveniently also used to sit on or as a backrest while relaxing on the deck.

Boat Hook:  A long stick with a hook at the end. Used to grab lines, items, and stuff that is too far to reach by hand, like cushions flying overboard. It is also convenient as a tool to push the boat away from another ship or the key. Or to push mud or clay off the anchor . Or catch a wild flying halyard. Most vessels have them on board, and you want one or two. (They tend to get lost at sea).

Guard Rail:  This can be a flexible wire or a solid metal rail surrounding the boat to prevent us from falling overboard. Some also use a net as an addition for increased safety.

Pushpit:  The metal guard rail around the stern of the boat. This is where the guard rail is secured on the stern. A common place to mount the BBQ, life raft, and the outboard for the dinghy. 

Pulpit:  The metal guardrail on the bow. This is where the guard rail is secured onto the bow.

Stanchion:  The metal bar that keeps the guard rail in place around the boat between the pushpit and the pulpit.

Arch:  A big structure usually made of stainless steel on the back of a boat. Often used to mount a variety of items like antennas, radars, solar panels, wind generators, etc.

Ground Tackle:  This consists of your  anchor , your anchor  chain,  the link between the two, and the connection between the chain and your boat. The ground tackle is basically the system that holds your boat to the ground.

Windlass:  The winch that hoists or lowers the anchor and chain. Most boats have one on the bow, and some have one on the stern, too. These incredible things can be electrical or manual (some are both) and are essential to anchor your boat when not in a port or marina. Try to haul the anchor manually once – you’ll put a windlass on the top of your wish list pretty quickly…

VHF   Radio:  Very High-Frequency Radio that broadcasts on the VHF network and makes you able to communicate with others around you. Sadly, you won’t be able to tune in to your favorite radio show on these. Still, they are invaluable at sea for communication.

Chart Plotter:  A navigation computer that shows various information on a screen, like charts, routes, radar images, etc.

Parts below the decks

Companionway:  The “front door” of the boat. This is where the steps lead from the cockpit or deck down below. It is usually opened and closed using a hatch, two doors, or a plate.

Galley:  The kitchen of a boat is never to be called a kitchen. Always use the term galley when you are onboard!

Saloon:  This is the boat’s living room and usually where you find the settee and dinette.

Settee:  The couch in a ship.

Dinette:  This is the area where you can sit down at a table and eat your dinner. It’s also perfect for consuming rum in good company and a game of cards.

Cabin:  These are the “rooms” onboard but might not necessarily be the “bedrooms.”

Head:  There are no bathrooms on a boat, only heads. If your skipper tells you to go and clean the head, getting out the shampoo won’t do you any good.

Nav station:  Usually a chart table and a console with mysterious instruments like radios, chart plotters, radar screens, and all sorts of complicated electronics. This is often where adventures are planned and the skipper’s favorite seat onboard. (At least, that is my favorite and where all this content is created!).

Bilge:  The space in the bottom of the hull where water collects and sometimes a storage space for all sorts of things. It usually contains a  bilge pump  to pump out water that finds its way into the boat in various places. You may have heard the phrase: “Treasures of the bilge.” Now you get it!

Berth:  A place in the boat where you can sleep. This doesn’t necessarily have to be a bed and can often include the sleeping space in the salon. The term  sea-berth  usually refers to a sleeping position where you are tucked well in and can sleep when the boat is heeling over and moving around.

V-berth:  The bed in the front cabin is shaped like a V.

Bulkhead:  A wall inside the boat, usually supporting the structure.

Terms used for directions and navigation

Port and Starboard : Port refers to the left side of the boat when facing the bow (front), while starboard signifies the right side. 

Windward and Leeward : The windward side refers to the side of a boat facing the wind, while the leeward side is the side sheltered from the wind. These sailing terms also apply to geographic features, like islands or coastlines, that offer protection from the wind.

Chart : A nautical chart is a map specifically designed for marine navigation, depicting water depths, shoreline features, navigational aids, and potential hazards.

Compass : A compass is an essential navigational instrument that indicates magnetic north, allowing sailors to determine their heading and steer their vessels accordingly.

Course : The course is a vessel’s intended direction of travel, expressed in degrees from true or magnetic north.

Heading : The heading is the actual direction a vessel points, also expressed in degrees from true or magnetic north.

Latitude : Latitude is a geographic coordinate that specifies a location’s distance north or south of the equator, measured in degrees, minutes, and seconds.

Longitude : Longitude is a geographic coordinate that specifies a location’s distance east or west of the Prime Meridian, measured in degrees, minutes, and seconds.

Waypoint : A waypoint is a specific location, defined by its latitude and longitude, that serves as a reference point for navigation.

Bearing:   The angle between the observer’s position and a distant object, measured in degrees from true or magnetic north.

Fix : A fix precisely determines a vessel’s position using various navigational methods, such as bearings, GPS, or visual landmarks.

Dead Reckoning : Dead reckoning is a method of estimating a vessel’s current position based on its previous position, speed, and course over time.

Tide : Tides are the regular rise and fall of sea levels caused by the gravitational forces exerted by the Moon and Sun. 

Current : Current refers to the horizontal movement of water in a particular direction. Currents can significantly affect a vessel’s speed and course, so make sure to consider them when sailing and navigating.

Buoy: A buoy is a floating device anchored in a body of water, such as an ocean, sea, lake, or river, to serve various purposes, including navigation, marking channels, identifying hazards, or indicating mooring locations.

The names of different sails and their parts

Mainsail:  The mainsail is the sail behind the mast and on top of the boom. 

Genoa :  A Genoa is a headsail that extends past the mast and overlaps the mainsail. 

Jib :  A Jib is a headsail that does not overlap the mainsail. 

Staysail:  A staysail is usually found on cutter rigs and is the sail set on the inner forestay.

Yankee:  A yankee headsail is used similarly to a Genoa or Jib but has a high-cut clew and is often used on cutter-rigged boats together with a staysail.

Mizzen sail:  A mizzen sail is typically a small triangular sail set on the aft mast of a boat with several masts, like the ketch rig.

Storm sail:  A storm sail is a small, strong sail to be used in heavy weather conditions where the headsail is furled to the point where its shape doesn’t give you drive anymore or/and when you want a smaller mainsail than your reefing setup allows you. The storm sails provide stability in the vessel in heavy weather sailing.

Spinnaker:  A Spinnaker is a symmetric light wind sail used to sail off the wind at deep angles between 120 and 180 degrees.

Gennaker:  A Gennaker is a cross between the Genoa and Spinnaker. It has the same type of light fabric as the Spinnaker but is asymmetrical like a Genoa with a tack set on the bow and a sheet led back from the clew to the stern of the boat.

Code Zero:  A code zero sail is a cross between a Genoa and a Gennaker. It is also designed for light wind with its lightweight fabric but has a different shape than a Gennaker. This makes it able to be used while sailing upwind, unlike the Gennaker.

Parasailor:  A parasailor is similar to a spinnaker but with some differences. It has a double-layer wing that inflates as the sail gets filled with air. This wing works like a batten and keeps the leech out while generating lift on the bow, making it effective between 70 degrees and all the way down to 180 degrees dead downwind.

The different parts of a sail

Tack:  The tack of the sail is the lower forward corner.

Clew:  The clew of a sail is the lower aft corner.

Head:  The top corner of a sail. 

Foot:  The foot of the sail is logically the bottom part of the sail between the clew and the tack.

Luff:  The luff is the front edge of the sail between the tack and head.

Leech:  The leech is the aft part of the sail between the clew and head. 

Telltales:  Telltales are small ropes, bands, or flags attached to the sail to give you an indication of the airflow around your sail. 

Battens:  Battens are slates or tubes inserted in pockets on the mainsail to help it keep its shape better and increase its lifespan.

Learn more about the different types of sails in this guide . 

Terms used when we talk about wind and weather

Gust : A gust is a sudden, brief increase in wind speed, often accompanied by a change in direction.

Squall : A squall is a sudden, strong wind that typically lasts for a short period and is often associated with rapidly changing weather conditions, such as thunderstorms or cold fronts.

Barometer : A barometer is an instrument used to measure atmospheric pressure. Changes in atmospheric pressure can indicate upcoming weather changes.

High-Pressure System : A high-pressure system is an area of relatively high atmospheric pressure, characterized by sinking air and typically associated with calm, clear weather.

Low-Pressure System : A low-pressure system is an area of relatively low atmospheric pressure, characterized by rising air and typically associated with clouds, precipitation, and potentially stormy conditions. Sailors usually refer to these systems as a “low.”

Front : A front is a boundary separating two air masses of different temperatures and humidity levels. Fronts are associated with changes in weather conditions and can cause sudden wind shifts and varying wind strengths.

True Wind Speed, or TWS: The actual wind speed affecting you at a point when you are standing still.

True Wind Direction, or TWD: The direction the wind is blowing from.

True Wind Angle, or TWA: The angle between your boat’s heading and wind direction.

Apparent Wind Speed, or AWS: The wind affecting the boat while in motion.

Apparent Wind Direction, or AWD: The direction of the wind in relation to your boat underway.

AWA  –  Apparent Wind Angle: The angle to wind while you are underway

Beaufort Scale : The Beaufort Scale is a system used to measure wind speed, ranging from 0 (calm) to 12 (hurricane). You can learn more about it at MetOffice here .

Saffir Simpson Hurricane Wind Scale: A scale describing hurricane wind speeds in categories from 1 to 5.

Learn more about the difference between actual and apparent wind in this guide .

Terms we use when cruising at speed under sail

Port Tack:  When the wind blows on the port side of your sails

Starboard Tack:  When the wind blows on the starboard side of your sails

Tacking: When you steer the boat from a starboard tack to a port tack and vice versa  upwind .

Gybing:  When you steer the vessel from a starboard tack to a port tack and vice versa  downwind .

Heeling : When the wind fills the sails and leans the boat over to the side.

NM:  Nautical Miles

Kt:  Knots – A measurement of speed used on boats.

Deg: Short for degrees

SOG: Speed over Ground, usually measured by GPS

SOW:  Speed over Water, usually measured by the boat’s speed log transducer.

COG:  Course Over Ground, the direction your boat is  moving  towards.

HDG:  Heading, the direction your boat is  pointing  towards.

Boom preventer:  A line or rope tied to the end of the boom and led forward of the mast to prevent it from swinging over when sailing off the wind.

Overpowered:  When wind overpowers the boats’ ability to steer a straight course. This typically happens when you try to sail above your boat’s hull speed, carrying too much sail area in relation to the wind, or your sails are poorly trimmed.

Hull Speed: The speed your boat has achieved when its created wave has the same length as the hull’s water length. Many displacement sailboats (the ones that don’t plane on top of the water) get hard to steer when going faster than this. You can learn more about how to calculate your hull speed in this guide: https://sailingellidah.com/average-distance-sailed-in-a-day/

Pro Tip:  Your COG and HDG will sometimes differ due to wind and current pushing you sideways.

Terms for the boats heading in relation to the wind

These sailing terms are best known as our points of sail and describe the vessel’s heading in relation to the wind:

Close Hauled:  When sailing close-hauled, the vessel’s heading is as close to the wind as possible, typically between 35-50 degrees.

Close Reach:  When sailing at an angle between 50 and 80 degrees, give or take.

Beam Reach:  The wind comes in from the side.

Broad Reach:  When bearing away from 90 degrees to around 135 degrees.

Running:  When sailing downwind.

Sailing Basics: 10 Nautical and Sailing Terms To Learn

terms on a sailboat

If you’re learning how to sail—or if you’re thinking about purchasing a sailboat of your own—these handy terms can provide a helpful overview of sailing basics you need to become familiar with.

Explore Sailboat Brands & Manufacturers

10 Nautical and Sailing Terms Everyone Should Know

1. aft .

The back of a ship. If something is located aft, it is at the back of the sailboat. The aft is also known as the stern. 

2. Bow 

The front of the ship is called the bow. Knowing the location of the bow of the boat is important for defining two of the other most common sailing terms: port (left of the bow) and starboard side (right of the bow). 

3. Port 

Port is always the left-hand side of the boat when you are facing the bow. Because “right” and “left” can become confusing sailing terms when used out in the open waters, port defines the left side of the boat as it relates to the bow or front.

4. Starboard 

Starboard is always the right-hand side of the boat when you are facing the bow. Because “right” and “left” can become confusing sailing terms when used out in the open waters, starboard defines the right-hand side of the boat as it relates to the bow or front.

5. Leeward 

Also known as lee, leeward is the opposite direction of the wind blowing (windward). 

6. Windward 

The direction in which the wind is currently blowing. Windward is the opposite of leeward (the opposite direction of the wind). Sailboats tend to move with the wind, making the windward direction an important sailing term to know. 

7. Boom 

The boom is the horizontal pole extending from the mast’s bottom. The sailboat can harness wind power to move forward or backward. This is done by adjusting the boom towards the direction of the wind. 

8. Rudder 

Located beneath the boat, the rudder is a flat piece of wood, fiberglass, or metal used to steer the boat. Larger sailboats control the rudder via a wheel, while smaller boats will have a steering mechanism directly aft. 

9. Tacking 

The opposite of jibing, this basic sailing maneuver refers to turning the boat’s bow through the wind so that the wind changes from one side of the boat to the other. The boom of a boat will constantly shift from one side to the other when performing a tack or a jibe. 

10. Jibing 

The opposite of tacking, this basic sailing maneuver refers to turning the stern of the boat through the wind so that the wind changes from one side of the boat to the other. The boom of a boat will always shift from one side to the other when performing a tack or a jibe. Jibing is a less common technique than tacking since it involves turning a boat directly into the wind.

Conclusion: Learn Nautical Terms Before Setting Sail!

In conclusion, knowing sailing terms and phrases is an essential skill for anyone who wants to take up sailing as a hobby. It enables sailors to communicate effectively with each other and understand the different parts of the boat and their functions. It also enhances safety and reduces the risk of accidents on the water. 

Therefore, whether you are a seasoned sailor or a beginner, learning these sailing terms can enhance your enjoyment of this exciting and rewarding sport!

Important Sailing Terms For Beginners

a boat on the hard which is one of the most popular sailing terms

We’ve all been there. In fact, sometimes I very much feel that I am still a beginner and I think any sailor that tells you they don’t have days where they feel like too is lying!

Sailing is ever-changing, and every situation is ever so slightly different. It’s one of the most wonderful things about sailing and one of the absolute worst!

But one thing is for sure, when you’re a beginner and being totally bombarded with sailing terms it’s really not helpful. You don’t need to know every single sailing term straight away. No matter what your crusty sailing instructor tells you!

There are however some really useful ones to learn straight away and these sailing terms will help you out a lot as you learn the ropes (or the lines, as us sailors like to say!) We’ve narrowed down the sailing terminology that we found essential when we started out sailing.

Focus on these for now and you’ll be amazed at how quickly the others become part of your everyday vocabulary as you learn to sail .

Aft : The back of the boat, or near the back of the boat. Aft basically means back!

Alongside: When the boat is next to a pier or another vessel.

Apparent wind : This is the wind that can be felt. It could refer to speed or direction, and is often different to the true wind. For example, if you are sailing forwards at 5 knts, the wind speed will feel stronger than if you are sitting still. The wind that can be felt is the apparent wind.

Astern : Behind the boat. Sailors often say ‘going astern’, which means going backwards or going in reverse.

Beam reach : A point of sail. When the wind is blowing perpendicular to the direction that you’re sailing.

Bearing away : Steering the boat away from the direction in which the wind is blowing.

Bilge : This is the bottom of the inside of the boat. Water collects in the bilge, and then you use a bilge pump to pump the water overboard. Many people store things in their bilge for longer passages.

Boom : This is the long pole that sticks out of the mast. It holds the bottom of the mainsail in place and can be moved from side to side depending on where the wind is coming from. Booms can be very dangerous, as they are heavy and tend to carry a lot of power when the sail is full of wind.

Bow : The front of the boat.

Broad reach : A point of sail. Sailing with the wind coming off your stern quarter, a position in between the beam and stern of the boat.

Cleats : The metal blocks to which you secure lines.

Close-hauled : A point of sail. Sailing as close to the wind as possible without the sails flapping. On a monohull, the boat will usually heel over the most on this point of sail.

Close Reach : A point of sail. When you’re sailing between a beam reach and close hauled. Again, as you are travelling towards to wind on this point of sail it is likely the boat will be heeled over.

Dead run or Running Dead Downwind : A point of sail. Sailing with the wind coming from directly behind the boat. Many people use a light wind sail to catch the wind if the conditions are right, or pole out a sail to be ‘wing on wing’ and catch as much of the wind as possible.

Draft: The depth of a boat when it’s sitting in the water.

Fender: An inflated bumper used to keep the boat from banging into the dock or another boat.

Genoa : A large forward sail that comes back past the mast when fully unfurled. It is the same as a job sail but larger.

Heave to: A sailing manouvre used mostly during storms, which lies the boat favourably to waves while making only very slight headway.

Jib : A triangular forward sail, smaller than a genoa.

Jibing : When you steer the boat downwind from one direction to the other to keep the sails full. As you move from one direction to the other the wind will come from a different side and the sails will need to be moved across the boat to keep them powered up. It is similar to tacking, but going downwind instead of up! There is more danger from the boom when jibing.

Mainsail : The main sail on the boat, attached to the mast.

Mayday : The emergency call you make over the radio to show the boat or crew are in distress and needs immediate assistance.

No-sail zone : Also called the dead zone. This is an area 45 degrees either side of directly into the wind. This is the area a boat can’t sail in, and your sails will flap and the boat will power down if you try.

Port : The left side of the boat when facing forward.

Reef : When you lower some of the sail to give less sail area to the wind, usually done as the wind speed picks up.

Sheet : A line or rope used to control the trim of a sail.

Starboard : The right side of the boat when facing forward.

Stern : The back end of the boat.

Tacking : Turning the boat into the wind to change direction. You will pass through the dead zone quickly, adjusting the sails to the other side of the boat so you can continue to sail towards the wind in a zig-zag type shape.

Topping lift : A rope running from the back end of the boom to the top of the mast. This line controls the height of the boom and prevents it from falling when the sail isn’t raised.

Winch : A mechanical device used to pull the lines that control sails.

Windlass : A winch used to raise and lower the anchor.

Most of the terms below you can muddle by without knowing and pick them up as you go.

A lot of them are just fancy terms for things you probably just use a different name for in every day life, and while they’re useful to have in your sailing vocabulary they can be communicated in other ways, or picked up as and when is necessary!

Sailing Terms: A Complete Guide

a sailboat in an anchorage

Here is a more comprehensive guide to different sailing terms. Feel free to look through them and start to get familiar with them if you’re a new sailor, but don’t let them overwhelm you! You will pick them up the more time you spend on the water and around other sailors.

Abeam : Anything to the side of your boat. If you spot a vessel beside you, you can say it is abeam, and people will know to look out at 90 degrees from the centreline of your boat.

Abaft : Towards the back of the boat. Anything abaft means towards the stern, so the life ring is abaft the mast, meaning the opposite of forward or the mast. It could also mean something behind the boat, like rocks or another vessel.

Abandon ship: A command given to leave the boat immediately. Usually given by the captain when the boat and crew are in serious danger.

Adrift: Unattached to the sea bed. It usually means a vessel that isn’t anchored and not under control, so free to float around where ever the wind blows.

Athwartship : The position across a vessel from side to side at right angles to the keel.

Backing (a sail) : Forcing the wind into the ‘wrong’ side of the sail by pulling it to the opposite side of the boat.

Backstay : The wire that runs from the back of the boat up to the top of the mast to stop it from falling forward. The backstay is often thicker and stronger than the other stays.

Bailer : A scoop that is used to collect water from the bottom of a vessel. It can be any container! You’ll want one in your grab bag for if you ever need to bail water from a life raft or a dinghy.

Ballast : Weight to add stability to your vessel. The weight is usually lead or iron and can often be found within the keel of the boat. Some boats add extra ballast for more stability.

Batten : A thin strip of fiberglass (usually) that slots into pockets of the mainsail to help it maintain an open shape. Battens run from the back edge of the sail, the leech, to the forward edge of the sail, the luff. Most will have more than one batten, but not all mainsails have battens.

Beam : The widest point of the boat.

Bend : A knot used to connect two ropes.

Berth : Berth has several meanings. It could be your bed onboard, or it could be your slip in a marina.

Bight : A bend in a rope or line. When a rope forms a bight, it has changed direction 180 degrees.

Bimini : The cover over the cockpit. Usually this is made from canvas and can be removed. It shades from the sun and offers a little protection from the rain.

Binnacle : The pedestal centrally located in the cockpit. It usually holds the steering wheel along with navigational equipment like your chart plotter and compass.

Bitter end: The last part of a rope or cable, usually referring to the anchor chain. Once the chain or rope has been paid out completely it has reached its bitter end.

Block : A pulley.

Boom vang : This prevents the boom and mainsail from moving upwards which sailing. It pulls the boom down to help the mainsail keep the right shape.

Boot Top or Boot Stripe : The paint between the boat’s bottom paint and it’s topside paint. It’s usually a white stripe that runs around the boat.

Bowsprit : A section of the boat that runs even further forward than the bow. It looks like a small diving board sticking out the front of the boat. Not all boats have a bowsprit and they are more common on classic boats. They allow the rigging to be attached further forward.

Broach : When a boat sailing downwind accidentally ends up sideways to the waves and heels over dangerously. This is usually caused by large waves that force the boat to travel too fast and end up in a position beam on to the waves.

Bulkhead : The walls in a boat that run across the centerline of the vessel. These are structurally important and mustn’t be messed with!

Capsize : When a vessel tips over past 90 degrees.

Catamaran : A vessel with two hulls.

an anchorage full of catamarans and monohulls

Centerboard : A keel that can lift up and down depending on the point of sail. It helps the boat to point further to wind when down, or run more easily downwind when raised. When raised, the boat can sneak into shallower waters.

Centerline : An imaginary line that runs all the way from the center of the bow to the center of the stern.

Chainplate : A metal plate attached to the hull of the boat, which the rigging is attached to. Chainplates are very important to hold the mast upright, and must be well maintained. Some are visible on the exterior and others are hidden on the interior.

Chandlery : A store that sells boat supplies.

Chock : A fitting that a line passes through to change direction without chafing.

Clew : The lower back corner of a sail, where the foot and leech of the sail meet.

Coamings : A area around the cockpit or hatches that is designed to keep out water.

Cockpit : The area where the helm of the boat is. It is usually where there is seating, and the entrance to the interior of the boat. Cockpits can be at the stern of the boat or in the centre. Some sailors prefer a centre cockpit for a feeling of safety, others prefer the extra space you get with an aft cockpit.

Dead reckoning : Determining a vessel’s position by knowing the direction and speed traveled.

Dinghy : The small, usually inflatable boat that you use to reach the shore when your big boat is at anchor. These are also called tenders.

Dodger : This is like the windshield of the boat. It’s a structure at the front of the cockpit to protect the helmsman from wind or spray.

Dismasting : When the mast breaks off. This usually happens because of a rigging failure, or can happen if the rig is overpowered.

Displacement : The weight of the water that would otherwise be in the place of the boat’s hull.

Drogue : A sea anchor to help slow down the boat. You might use one in big seas when the boat is sailing too fast down the waves. It can look like a small parachute on a line that you hang off the back of a boat, or even just a line or several lines hanging from the stern can help to slow the boat down.

Ebb tide : After high tide when the water is receding towards low tide.

EPIRB : Emergency Position Indicating Radio Beacon. This device transmits a distress signal to alert emergency services to the position of a vessel in trouble. Most people carry an EPRIB in their grab bag, or an easy to reach place in the boat.

the foot (sailing term) bottom edge of a sail

Foot : The bottom edge of a sail.

Fore : At or near the bow (front) of a vessel.

Forestay : The rigging wire which goes from the bow to the top of the mast. This is where the foresail is attached, either hanked on or using a roller furling system. Most modern boats use a furling system as it is easier and quicker to use.

Full keel : A fixed, ballasted keel running the whole length of the boat.

Furling system : The system used to roll up a sail when it’s not in use and unfurl it when it is. It is most common to find furling foresails but in mast furling for the mainsail has also become more popular over recent years.

Freeboard : The distance on a vessel from the waterline to the deck.

Galley : The kitchen!

Gelcoat : The paint used on the outside of a boat. It’s a tough resin that forms a protective coating.

Gimbals : You will usually find these on your galley stove. They make your oven act a little like a rocking crib, so that it can stay level even when the boat is heeling or rocking. This is essential for keeping things on the stove while sailing or in a rolly anchorage.

Gooseneck : The point at which the boom attaches to the mast, letting the boom move freely from side to side and up and down. You then use lines to control it!

Ground tackle : The anchor, chain, and line that you use for anchoring or fixing the boat to the bottom of the sea when you want to stop and stay put.

Gunwale : The top edge of a boat’s hull.

Halyard : The line which attaches to a sail to raise it.

Hanks : The clips that attach the front edge of a sail to the forestay. It is more common these days to use a furling system for your main forestay, so you will likely only see these on a storm sail.

Hatch : A window in the ‘roof’ of the sailboat. It opens out onto the deck.

Head : The bathroom on a boat.

Headway : The amount you’re moving forward through the water. Like ‘making headway’.

Heave to : A way to keep the boat from moving through the water with minimal drift, usually used in heavy, dangerous seas. You back the foresail but lock the helm hard over towards the wind. Your boat should sit nicely creating a slick over breaking waves and you should only drift a little through the water. Not all boats will heave to nicely, so you should test this method with your vessel.

Heel : The tilt of a sailboat that usually happens when you’re sailing towards the wind.

In-Irons : When you steer the boat into the wind (by accident or on purpose) and the sails lose power. The boat will lose steerage as it slows down.

Jackline or Jackstay : Safety lines that run from the bow to the stern. You can clip yourself onto these lines so that you don’t fall overboard when doing tasks that require you to leave the cockpit.

On the hard : When your boat is out of the water, usually in a boat yard.

Painter : The line which attaches your dinghy to your main boat.

Pan Pan : This is a distress call that isn’t quite as urgent as a Mayday call. You will put out a pan pan on the radio if your boat needs assistance or you want to alert the emergency services of a problem that might get worse and become a mayday. For example, you have lost your engine and will drift into rocks if you can’t solve the problem or the wind doesn’t pick up in time.

Points of sail : The way your boat is travelling in relation to the wind.

Port tack : Sailing with the wind hitting the port side of the vessel.

Pulpit : The metal rails at the bow of the boat.

Pushpit : The metal rails at the back of the boat.

Shrouds : Wires or ropes running from the chainplates to the mast to stop the mast moving from side to side.

Skeg : An extension of the hull hanging in front of the rudder, that the rudder is attached to. It can help protect the rudder from getting hit or from debris in the sea.

Sloop : A single masted sailboat with a mainsail and one foresail.

Slugs : The things that the mainsail sits in to run it up the boom.

Spinnaker : A sail used for light, downwind sail. Spinnakers are often the biggest sail on the boat, made from a light material and they are often brightly coloured.

Splice : When you connect two lines together using their weave. You will often need a fid for this.

Spreaders : The horizontal poles that come out from the sides of the mast.

Spring line : These are used when docking the boat. They are the lines that come from the bow or the stern to a point midship on the dock. They are used to control how far the boat can move forwards and backwards while in its slip.

Stanchions : The metal posts along the outside of the deck through which the lifelines run.

Standing rigging : The wires and ropes, such as the shrouds and stays, that are permanently in place and hold up the mast.

Storm jib : A small foresail that can be hanked on during heavy weather. It is made from tough, heavy material and often brightly coloured.

Tack : The forward lower corner of a sail.

Tender : The same as a dinghy. A small boat, usually inflatable, that you use to get to shore when the boat is anchored.

a family on a tender, which is a sailing term for dinghy

Tiller : A bar used to control the rudder from the cockpit. It is the same as a steering wheel, but some prefer using a rudder, or find it takes up less space in the cockpit.

Toe rail : The raised lip around the edge of the deck that helps stops things falling overboard.

Trim : Adjusting the shape and angle of the sails to get optimum performance.

Watermaker: A device used on board sailboats to make fresh drinkable water from the sea.

Weather helm: If the helm was centered, the boat would turn towards the wind (weather). Because of this, the tiller must be pulled to the windward side of the boat in order to make the boat sail in a straight line.

Windward : The direction from which the wind is blowing.

Wing on wing : Sailing downwind with the foresail and the mainsail out on different sides of the boat to catch as much of the wind as possible.

terms on a sailboat

Short answer sailing terms and phrases:

Sailing terms and phrases refer to language specific to the sport of sailing. They include terms related to boat parts, sailing maneuvers, wind direction, and navigation. Understanding these terms is crucial for effective communication and safe sailing practices.

Understanding the Basics: A Guide to Sailing Terms and Phrases

Welcome aboard, fellow sailors and landlubbers alike, as we embark on a voyage through the mesmerizing world of sailing terms and phrases. Whether you’re an enthusiastic beginner or a seasoned seafarer looking to brush up on your nautical knowledge, this guide will have you speaking like a true sailor in no time.

As with any specialized field, sailing has its own unique language that can bewilder even the most erudite wordsmiths. But fear not! We’re here to break down the basics and shed light on those mysterious terms that have been floating around in your mind like buoys at sea.

Let’s start by hoisting the main sail and diving headfirst into some essential terminology:

1. Port and Starboard: If someone shouts “Hard to port!” during your sailing adventure, don’t panic – they simply mean turn left. In maritime lingo, “port” refers to the left side of a vessel when facing forward, while “starboard” is the right side. Thinking of them as counterparts can help avoid confusion during moments of high-seas excitement.

2. Bow and Stern: Don’t forget where your front and back are while navigating the open waters. The bow is the forward part of the vessel (a great spot for taking epic photos), while the stern is located at the rear. Trust us – being able to differentiate between these two proves invaluable when following directions or describing intriguing sights.

3. Aft vs Forward: Just as knowing which way is up is vital for surviving gravity’s pull, understanding aft (the back part of a ship) versus forward (the front part) is crucial aboard a boat too! Being able to navigate with ease relies heavily on using these terms correctly when maneuvering around onboard.

Now that we’ve set our bearings straight let’s proceed further into more advanced seamanship jargon:

4. Shiver me Timbers: Ahoy, matey! Surely, you’ve heard this catchy phrase in pirate movies or read it in adventure novels. But do you know what it means? “Shiver me timbers” originated from the old seafaring days when wooden ships were prevalent. When they were hit by fierce storms or cannonballs, the creaking and vibrations of the hull made the timber “shiver.” Nowadays, it’s an exclamation expressing surprise or disbelief.

5. Nautical Mile: Avast, ye landlubbers! A nautical mile is a unit of measurement used specifically for sea and air travel. It’s equal to one minute of latitude along any meridian – approximately 1.15 statute miles (or about 1.85 kilometers). So, whether you’re voyaging across vast oceans or navigating through treacherous straits, understanding this term will keep you on course.

6. Windward and Leeward: When sailing the high seas, understanding wind patterns becomes crucial to harnessing their power effectively. Windward refers to the direction from which the wind is blowing (usually against your face), while leeward indicates the sheltered side where the wind is blocked by your vessel or other objects nearby. Skippers who can master these concepts will navigate their vessels with grace and ease.

7. Keelhaul: Now here’s a term that harkens back to darker maritime times! To keelhaul someone often meant dragging them under a ship’s keel as a form of punishment. Luckily for us nowadays, it has mostly been relegated to seafaring folklore and modern-day sailors rarely seek to employ such discipline.

So there you have it – a comprehensive yet entertaining guide to essential sailing terms and phrases that will surely make waves amongst your fellow salts-in-arms! From knowing your port from starboard all the way down to deciphering historical jargon like “shiver me timbers,” embracing these nautical expressions will not only deepen your understanding but also add a touch of maritime flare to your conversation.

So raise your glasses – or rather, yer grog – as you confidently navigate the mighty seas armed with newfound knowledge, humor, and a dash of seafaring slang. Bon voyage!

Frequently Asked Questions about Sailing Terms and Phrases Answered

Sailing is a unique and exciting experience that brings together the beauty of nature and the thrill of adventure. Whether you are an experienced sailor or a novice looking to learn more about this captivating activity, it’s important to understand the various sailing terms and phrases that are commonly used in the sailing community. To help you navigate through these sometimes confusing waters, we have put together a list of frequently asked questions answered with detailed professional explanations, sprinkled with witty and clever anecdotes. So sit back, relax, and let’s dive into the world of sailing terminology!

Q1: What exactly is a “jib”?

A1: Ah, the jib! This term refers to a triangular sail located at the front of the boat, usually attached to the forestay (the wire that holds up the mast). The jib serves as one of the primary sources of propulsion for sailing vessels. Think of it as the boat’s secret weapon – it catches wind and propels your vessel forward! Just like a jester adding an element of surprise in medieval courts.

Q2: Can you explain what “tacking” means?

A2: Tacking is perhaps one of the most fundamental maneuvers in sailing. It involves turning your boat into or across the wind so that your sails switch sides. Picture yourself maneuvering your way through rush hour traffic – except instead of cars, there are waves crashing against each other! Tacking allows sailors to make headway against windward, zigzagging their way to their destination like Shakespearean characters in a fiery debate.

Q3: I’ve heard people talk about “heeling.” What does it mean?

A3: Ahoy there! Heeling refers to when a sailboat leans over sideways due to strong winds pushing against its sails. This ‘Michael Jackson-esque’ dance move can be quite exhilarating for thrill-seekers, but it requires careful balance and control. Imagine holding a delicate ballet pose on a tilting stage while attempting to impress the judges. That’s what heeling is all about – finding the perfect equilibrium between adventure and stability.

Q4: What is meant by “mainsail”?

A4: The mainsail is the largest and most visible sail on a sailing vessel. It is typically attached to the mast and plays a crucial role in powering the boat forward when the wind hits it just right. This sail can be compared to the lead vocalist of a band – it takes center stage and commands attention, providing maximum power to propel your floating oasis across the water.

Q5: Can you explain what “port” and “starboard” mean?

A5: Ahoy, matey! Port refers to the left side of a boat when facing its bow (front), while starboard refers to its right side. Now, how do you remember which is which? Here’s a clever trick: port has four letters, just like LEFT, so it’s easy to associate them together. And starboard has more letters than port or left, so that must be RIGHT! Remember this little rhyme, and you’ll never steer your ship in the wrong direction again.

So there you have it – some frequently asked questions about sailing terms and phrases answered with detailed professional insight mixed with witty and clever comparisons. We hope this helps unravel some of the mysteries behind those nautical expressions that sailors throw around with ease. Happy sailing!

Mastering the Jargon: Unraveling the Language of Sailing

Sailing, with its long and storied history, offers enthusiasts an escape into a world rich in tradition and adventure. From battling treacherous waves to navigating the vast expanses of the open sea, sailors are no strangers to challenges. However, there is one aspect of sailing that can often leave beginners feeling adrift – the intricate and sometimes befuddling language used in this esteemed practice.

In this blog post, we aim to demystify the jargon of sailing, allowing novices to navigate conversations with seasoned sailors and ultimately feel more at home on deck.

Tacking and Jibing – Oh My!

One of the most fundamental concepts in sailing revolves around changing direction – but don’t call it turning! Sailors use specific terms like tacking and jibing to describe these maneuvers. Tacking involves turning into the wind by steering through a series of tight angles, while jibing entails turning away from the wind in a more fluid motion. So if you hear someone say “Prepare to tack!” or “Jibe ho!”, now you’ll know what they mean.

Hoist That Main Sail!

As you familiarize yourself with sailboats, you’ll swiftly encounter talk about different sails – mainsails being one of them. The mainsail is crucial for propelling your vessel forward and adjusting its position relative to the wind. When you hear someone shout “Hoist that main!” they’re simply telling their crewmates to raise or unfurl this essential sail. Remember, timing is key when hoisting your main as it affects your boat’s performance and maneuverability.

Trimming Your Sails

Ever wondered what sailors mean by “trimming” their sails? No, they’re not talking about giving them a haircut! Trimming refers to adjusting your sails’ position relative to the wind for optimal efficiency – something akin to finetuning your instrument. By playing with the sheets (lines that control sail shape), sailors can harness the wind’s power effectively, propelling themselves along smoothly and efficiently.

The Wind Angle – A Sailor’s Best Friend

Understanding wind angles is paramount for any sailor worth their salt. When sailors refer to “the point of sail,” they are describing the direction they are sailing relative to the wind. Different points of sail include close-hauled (sailing as close to the wind as possible) and running (sailing in the same direction as the wind). Knowledge of these angles determines how a skilled sailor adjusts their sails, achieving optimal speed and stability.

Raising Anchor – Setting Sail!

Embarking on a sailing adventure often begins with raising anchor or setting sail. However, it’s not just about hoisting a heavy object; there is an art to it! The crew works together seamlessly, making sure the anchor is secured safely before preparing to lift it from its watery resting place. With a well-coordinated effort, they can free themselves from shore and set out into open waters to seek out new horizons.

Navigating Lingo Land

As you delve deeper into sailing culture, you’ll soon notice a myriad of unique terms specific to this maritime world – jargon like ‘batten down the hatches,’ ‘hard-a-lee,’ or ‘full-and-by.’ Each phrase has its own charm and colorful history that adds character and camaraderie amongst sailors. Embrace this lexicon with enthusiasm, for it symbolizes connection with centuries-old traditions and ensures clear communication at sea.

So whether you decide to hoist your sails under clear blue skies or undertake epic adventures across stormy seas, mastering the jargon of sailing will undoubtedly enhance your experience. Armed with this newfound knowledge, you’ll be able to hold engaging conversations with fellow sailors while feeling like an old salty sea dog yourself. Fair winds ahead!

Taking Your Boating Game Up a Notch with Essential Sailing Terms and Phrases

Are you ready to elevate your boating skills and impress everyone on board with your extensive knowledge of sailing terms and phrases? Look no further, as we’re here to help you take your boating game up a notch!

Sailing has its own unique language that can initially seem daunting to beginners. However, mastering these essential sailing terms and phrases not only enhances your understanding of the sport but also ensures seamless communication with fellow sailors. So let’s dive into this linguistic adventure and emerge as refined seafarers!

1. Bow: This term refers to the front part of the boat. Imagine standing at the bow, with the wind blowing through your hair, as you confidently navigate through the open waters.

2. Stern: The opposite of the bow, the stern is the back end of the vessel. Picture yourself lounging on the stern while basking in the sun, enjoying a leisurely day on your boat.

3. Port: When facing forward towards the bow, port refers to the left side of a boat or yacht. Remember it by associating “port” with “left,” both consisting of four letters.

4. Starboard: In contrast to port, starboard indicates the right side of a boat when facing forward. An easy way to remember is by imagining a bright star guiding you towards success.

5. Tacking: To change direction against or across the wind using sails is known as tacking. It involves turning or pivoting through head-to-wind coordination, allowing your boat to zigzag efficiently while harnessing variable wind angles.

6. Jib: A triangular sail positioned in front of a mast is called a jib and primarily aids in steering when sailing close-hauled or reaching conditions.

7. Mainsail: The largest sail on most boats, attached vertically along a mast toward aft (near stern) direction commands utmost respect – it’s called a mainsail! Mastering control over the mainsail is essential for maximizing speed and maneuverability.

8. Windward: The direction from which the wind is coming is referred to as windward. Sailing toward the windward side can be challenging yet exhilarating, requiring precise navigation techniques for optimal performance.

9. Leeward: The opposite of windward, leeward denotes the side away from the wind or downwind direction. When sailing on the leeward side, you’ll experience smoother conditions with less turbulence — a perfect opportunity for relaxation and enjoying your boating adventure.

10. Rudder: Acting as a ship’s steering mechanism, the rudder controls its movement by changing its course in response to the helmsperson’s commands. Mastering rudder control ensures smooth sailing and accurate navigation.

Now armed with these essential sailing terms and phrases, you can confidently navigate through any boating expedition while impressing your friends with your newfound knowledge! So hoist those sails, trim them accurately, and let these words navigate you towards becoming an impeccable sailor. Fair winds and following seas await you on this exciting journey!

Remember, practice makes perfect, so don’t hesitate to apply these terms during your next sailing adventure. Happy sailing!

Sailing Terms Demystified: A Comprehensive Guide to 14 Common Sailing Terminology

WOS Team

Sailboats sailing towards the horizon

Ahoy, sailors! If you’re new to the world of sailing, you might find yourself overwhelmed by the myriad of sailing terms that seasoned sailors casually toss around. But fear not! In this comprehensive guide, we’ll unravel the mystery behind common sailing terms, providing simple explanations and examples to help you navigate the nautical jargon with ease. Let’s set sail and explore these essential sailing terms.

Table of Contents

Port and starboard.

When on a boat, “port” refers to the left side, while “starboard” refers to the right side. These terms are used to communicate directions and indicate the location of objects or maneuvers. For example, “Please pass me the fenders on the starboard side.”

Bow and Stern

The “bow” refers to the front or forward part of a boat, while the “stern” refers to the back or rear part.

Windward and Leeward

“Windward” refers to the side of the boat or the direction from which the wind is coming. On the other hand, “leeward” refers to the opposite side, sheltered from the wind. Sailors use these terms to plan their course and make tactical decisions.

Tacking and Jibing

“Tacking” is the act of turning the bow of the boat through the wind, changing the side from which the wind is coming. This allows the boat to change direction while sailing upwind. “Jibing” is the opposite maneuver, turning the stern of the boat through the wind to change direction when sailing downwind.

“Rigging” refers to the system of ropes, wires, and other components used to support and control the sails and mast. It includes various elements such as halyards (ropes used to hoist the sails), sheets (ropes used to control the angle of the sails), and shrouds (wires supporting the mast).

“Heeling” describes the leaning or tilting of a sailboat due to the force of the wind on the sails. The boat can lean to one side, causing it to tilt and creating a thrilling sensation. Sailors adjust the sails and shift their weight to maintain balance and control.

“Reefing” is the process of reducing the area of a sail to decrease its surface area and power in strong winds. This is done by partially lowering or folding a section of the sail and securing it, thus making the sail smaller and more manageable.

The “keel” is the central structural element of a sailboat, usually made of heavy material such as lead or iron. It extends beneath the boat into the water and provides stability and prevents the boat from sliding sideways.

Navigational Markers

Navigational markers, also known as buoys, are floating objects that indicate safe passages, hazards, or important locations in the water. They are color-coded and labelled according to their purpose. For instance, a red buoy with even numbers indicates the right side of a channel when entering from the sea.

Points of Sail

Sailboats have different angles at which they can sail relative to the direction of the wind, which are called “points of sail.” The main points of sail include close-hauled (sailing as close to the wind as possible), reaching (sailing at an angle between close-hauled and a broad reach), and running (sailing with the wind directly behind).

By familiarizing yourself with these essential sailing terms, you’ll be able to communicate effectively, understand instructions, and navigate the sailing world with confidence. So hoist your sails, embrace the wind, and embark on unforgettable nautical adventures armed with the knowledge of sailing terminology. Fair winds and smooth seas!

100 Sailing Terms You Need To Know in 2023

Boost your sailing vocabulary with these terms. In compiling this list, we’ve stuck with terms used today. So, you won’t find pirate lingo like, “Avast ye matey, or walk da plank!” Instead, this is a list of a bunch of things a newbie would want to know before stepping aboard a boat.

This list of sailboat terms might look slightly intimidating initially, but it’s only meant as an introduction. A few trips on the water and a few good sailing movies into your new lifestyle will set you straight. Soon, you’ll be “cooking the galley” and “hitting the head” in your Midtown apartment, making your friends wonder what has gotten into you.

Table of Contents

Sailing direction terms – orientation from your boat, basic sailing terms – points of sail from starboard tack to sailing downwind, sail boat terms – types of sailboats by rig, sailing vessel terminology – names of sails and rigging, sail terms for the parts of a sail, sail boating terms for parts of a boat hull, where do sailors rest on a ship down below, sailing lingo out on the ocean, sailing terminology faqs.

sailing terms

Before you can set sail, it’s good to know which direction you’re headed. While sailors love technicalities like north, south, east, and west, it’s usually more convenient to reference the world based on the boat beneath their feet. It’s the same for everyone, no matter where they might be–as long as they’re all in the same boat.

Many of these words, and many words on the rest of this list, might be combined with others. Examples will be included.

Port The left side of the boat when you are looking forward. Port is used to describe anything found on the left side, like the port engine or the port-side dock line.

Starboard The right side of the boat when looking forward. These aren’t confusing once you get the hang of it, but here are a few tips to get you started on how to remember port and starboard .

Fore Anything on the forward half of the boat.

Aft Anything in the back half of the boat.

Amidships Anything in the middle of the boat.

Abeam Something that is right off the side of the boat.

Bow The pointy end of the boat. You can combine it with directional terms, like “Look off of the port bow.”

Quarter The quarters are the aft sides of the boat, as in, “There’s a ship coming up on our starboard quarter.”

Apparent Wind Sailors love using the wind as a reference. The apparent wind is the wind you feel on deck, which is the sum of both the boat’s movement and the true wind.

True Wind What the weather provides, regardless of what it feels like on deck. For example, if there are 10 knots of true wind from the north and you are motoring north at 5 knots, you will feel 15 knots of apparent wind on deck. On the other hand, if you are sailing south, you would feel 5 knots of apparent wind on deck. In either case, the true wind is 10 knots.

Leeward The side of the boat that is downwind or away from the wind. If the boat is heeling, then the leeward side is the lower side.

Windward The side of the boat facing the wind. If the boat is heeling, the windward side is the high side.

Sailors love to talk about the wind, and so each of the points of sail has its own terms for what the sails are doing.

In Irons A boat cannot sail into the wind. If it’s pointed dead into the wind, the sails will flap, and the boat will stop. Sails don’t flap, by the way. They flog or luff .

Tacking Tacking is how sailboats sail upwind. They cruise in a zig-zag course, about 45 degrees off the wind blowing. Each turn through the eye of the wind is called a tack. Tacking is tedious. Sailors sometimes call it “beating into the wind.”

Close Hauled When you’re sailing as close to the wind as the boat can, you are close hauled.

Close Reach If you head down (away from the wind) a little, you are close reaching. The sails ease out a bit, and the boat speeds up.

Reaching or Beam Reach Reaching is when the wind is off the boat’s beam. This is a sailboat’s fastest point of sail.

Broad Reach Continue turning downwind, and you will be broad reaching.

Running Running is when you are sailing downwind.

Heave To Heaving to is a maneuver where you steer the boat into the wind and make it stop. It’s handy to use if you need to fix something or just want to stop to take a break. Sailors should also know how to heave to when heading offshore, as it’s a good storm tactic in many boats.

Reef To reef a sail is to shorten sail, which is handy when it gets too windy for your liking. Reefing allows you to slow the boat down, ride more level, and reduce stress on the rig and the crew. Knowing how to reef a sail is a vital skill for all sailors.

Sailboats are classified based on their rig, so different designs each have their own name. We won’t go into barques and tall ships here since you won’t be seeing those every day.

Rig The masts and booms that hold the sails up.

Mast Head Rig A mast head rig has the forward sail attached at the masthead.

Fractional Rig The opposite of a masthead rig, a fractional rig has the forward sail attached lower than the top.

Sloop A single-masted sailboat with a large mainsail and a large forward sail (the jib).

Cutter A single-masted sailboat with a large mainsail and two smaller forward sails, the jib and staysail.

Ketch A two-masted sailboat with the rear mast being shorter than the main. The rear mast is called the mizzen mast. The mizzen mast is attached forward of the rudder post.

Yawl Two masts, with a shorter mizzen mast rigged behind the rudder post.

Schooner Has two or more masts of equal heights.

We’ve touched on some of these, but individual sails and parts of the rig also have names. We’re only talking about the fore and aft sail inventories found on modern sailboats here, not square-rigged tall ships.

Mainsail The primary sail, which is carried on the main mast. If you want to sound traditional and salty, you could also spell it “mains’l,” since that’s how it’s pronounced anyway. Usually the main is the most important sail and often the one with the most sail area.

Headsail Another word for foresail, or a sail mounted on the front of the boat.

Jib The most common type of headsail. A 100-percent jib fills the foretriangle in front of the mast.

Genoa If the sail extends farther aft than the mast, it is a genoa. 110 and 135 percent genoas are common on sloops. Although, many sailors would still call them jibs.

Staysail A stays’l is a smaller headsail that mounts inside of the jib or genoa. They are a fixture on cutters, but many sloops and ketches have them added for heavy-weather sailing.

Downwind Sails Sails can be designed to be good upwind, good downwind, or okay at both. A downwind sail is usually larger and lighter than an upwind sail. It will have more shape to it, too.

Spinnaker The classic downwind sail is a spinnaker, a huge billowing sail usually made from colorful nylon. Spinnakers can be symmetrical or asymmetrical. Most cruising sailors use asymmetrical spinnakers since they require less rigging and can also be used on broad reaches.

Code Zero A code zero is a downwind sail that also does some teaching. It looks like a cross between a giant genoa and a spinnaker.

Mizzen Sail The mizzen sail is a small sail flown from the mizzen mast. If a boat is sailing with its jib and mizzen only, it is called “ jib and jigger .”

Boom Horizontal spars that hold the foot of a sail. Usually on the main and mizzen, but sometimes jibs and staysails have booms, too, to improve sail shape.

What’s that, the “foot” of the sail? That’s right, the parts of each sail has it’s own name, too. A square sail would have a few extra parts, but we’ll skip those since they are pretty rare.

Head The upper point of a triangular sail.

Clew The back lower corner of a triangular sail.

Tack The forward lower corner of a triangular sail.

Foot The bottom edge of a sail.

Leech The forward edge (leading edge) of a sail.

Luff The rear (trailing) edge of a sail.

Enough talking about sails and sailor stuff. Let’s dive into some terms that apply to nearly every kind of vessel.

Fiberglass The main component that modern boats are made of. It is also called FRP, or fiberglass reinforced plastic.

Gelcoat Fiberglass is coated in a colored resin that protects it from water and the sun’s UV rays. Gelcoat is usually white, although it can be tinted any color.

Bow The forward, “pointy end” of the boat.

Bowsprit If the boat has a spar or platform extending forward of the hull, it’s called a bowsprit.

Stern The rear of the boat. On boats that have a flat stern, the flat part is called the transom. (I wrote about it in detail here: What Is the Transom on a Boat )

Beam The widest part of the boat. What is a boats beam is usually a key figure when determining how it will handle.

Keel The center strip of a boat’s hull that runs from the bow to the stern. The shape of a boat’s keel depends on its purpose. A sailboat will have a deep keel to counter the effects of the wind on the sails. A powerboat will have a flat keel to help it get up on plane.

Ballast Weight added to the bottom of a boat (or to its keel) to help make it stable. For example, the keels of sailboats have thousands of pounds of lead ballast built into them.

Sea Cock A rooster stuck on a boat. Ha! No, a sea cock is an underwater valve installed on a boat that lets water in or out through the hull. Most sink drains go out through sea cocks, and the engine and other appliances get water from them.

Rudder Mounted on the stern of a boat, the rudder moves when the skipper moves the steering wheel. The rudder makes the boat turn left or right.

Running Gear The generic term given to the underwater equipment that makes the boat move–the propeller and prop shaft.

Freeboard The height of the sides of the boat above the water. A boat with a lot of freeboard is tall, and the decks farther out of the water.

Coach House/Coach Roof On a sailboat, the cabin area is called the coachroof. However, some boats have a flush deck, so they don’t have a coachroof.

Monohull A vessel with a single hull.

Catamaran A vessel with two hulls of equal size, connected together over the water by a bridge deck.

Trimaran A vessel with three hulls, or–more accurately–a primary center hull with two smaller outboard “amas.”

Now for a tour below decks.

Cockpit The open area on the back of a boat, usually where you drive the boat from. On most boats, there is space to hang out and perhaps even eat a meal in the cockpit. It’s like the boat’s patio.

Helm The location where the operator steers the boat with a wheel or tiller. The helm for a boat could be inside or outside, and many boats have more than one.

Companionway On a sailboat, the main entrance way to the cabin.

Cabin The living space or enclosed area of the boat.

Portlight Windows that open to let air in.

Deadlight Windows that don’t open.

Hatch An overhead window that opens.

Salon/Saloon The main “living room.”

Galley The kitchen on a boat.

Head The bathroom, lavatory, washroom, water closet, WC, loo, or whatever you like.

Stateroom/Cabin The bedroom.

Bunk The bed.

Berth A smaller bed.

Bilge The lowest point of the boat, underneath the cabin sole (floor boards).

Engine Room The room where the engine lives.

Forepeak The part of the inside of the boat that is up in the bow. Most boats have a locker here to store their ground tackle.

Locker A cabinet.

Bulkhead A wall.

Okay, you know all about your boat, its parts, and its rooms. So let’s set sail and talk about why we’re here in the first place. Let’s go boating!

On Passage A passage is a long voyage, usually offshore. When sailors talk about setting off on a long trip, they talk about it in terms of individual legs, or passages.

Off Soundings When the water is so deep that the depth sounder no longer works, you’re off soundings.

On Watch All vessels must maintain a lookout by sight and sound for other vessels at all times. It is the bedrock of safety at sea and the international laws governing preventing collisions ( COLREG s). The person with this duty is “on watch” or “standing watch.”

Bluewater A general term for ocean sailing. A bluewater sailboat is needed to go on a bluewater passage, and anything could happen out there.

Coastal Cruising Near-shore sailing is usually only a few hours away from civilization.

Inland Cruising on rivers and lakes that are not on the ocean. Technically, even most estuaries and bays are “inland.”

Milk Run A term given to an easy passage that is made downwind in good weather. The Coconut Milk Run is the passage from the Americas to the islands of the South Pacific.

Rally Organized passages or longer trips, like the World ARC , an annual around-the-world rally.

Shoal An area of shallow water. It can be a verb, noun, or adjective. As in, “The water shoals near the point,” “There’s a shifting shoal over there,” or “The shoal water comes right up to the channel.”

Bar The common occurrence of shoal water at an inlet. In windy weather, seas can break on the bar and create hazardous conditions.

Channel A deep-water (or deeper, at least) path that boats can take through an area of shoals.

Anchorage A good spot to drop the hook. Some anchorages at shown on charts; others are just made up by folks who like to anchor there. A good anchorage should protect you from waves and wind.

Mooring A mooring is a permanent anchor that the boat can be attached to. It’s usually marked by a mooring ball, a white buoy with a blue stripe.

Buoy A floating marker that indicates a channel, obstacle, or mooring.

Daybeacon A Coast Guard marker that shows a channel, usually green squares or red triangles. Some might also have lights on them. They are shown on charts to help you navigate.

ATON Aid To Navigation, the Coast Guard’s term for buoys, day beacons, and lights.

Nautical Mile or Knot Distance at sea is measured in nautical miles (nm), which differs from the statute miles used on land. One nautical mile is an international standard, so even places that use kilometers would use a nm at sea. 1 nm = 1.15 sm = 1.85 km

A nautical mile per hour is called a knot.

sailing terms on passage nautical miles

What do sailors say when they set sail?

When the boat leaves the dock, it is “casting off” or departing.

What is the term for sailing into the wind?

Sailing into the wind could be called “sailing to weather.” Alternatively, some sailors might call it “beating.” To sail into the wind, a sailboat must “tack”–the act of turning back and forth in a zig-zag pattern. This is because a sailboat cannot sail directly into the wind.

What is it called when you go sailing?

Some people call it a lot of fun, but others have a miserable time–sailing has been called all sorts of things. If you’re going on a trip, most boaters would say that they are going “cruising.” If they’re crossing an ocean or making a long trip, they’re going on a “passage.” But if you’re just on the boat for a day, you’re going “boating” or “sailing.” Sailing would specifically require using sails, so powerboats go on trips, not sails.

40 Sailing Terms: How to Talk Like a Sailor

By: Zeke Quezada, ASA American Sailing , Nautical Trivia

In 1983, the American Sailing Association was founded by Lenny Shabes. Over the years, hundreds of thousands of sailors have become certified in the ASA sailing curriculum. This year, we celebrate 40 years as the leading sailing education entity in the United States. So when you get out on the water, you can be sure that ASA-certified sailors are sailing safely and confidently.

Sailing has its own language, and when you go through the ASA curriculum, you’ll find yourself using terms like port and starboard if talking about directions, or referring to a zephyr or a squall when discussing the weather. Some language is meant to help clarify sailing directions, while other terms sound like novelties or just sailors loving that we are part of a special club, but actually have super interesting origins and stories tied to them.

After 40 years, we are going strong, and we continue to help students not only talk like sailors, but become sailors. 

40 terms to help you start talking like a sailor

  • Aft – The rear section of the boat
  • Bow – The front section of the boat
  • Mast – The vertical pole that supports the sails
  • Boom – The horizontal pole that extends from the mast and supports the foot of the mainsail
  • Winch – A device used to adjust the tension on a rope or wire, usually used to hoist sails or adjust rigging
  • Helm – The steering wheel or tiller used to steer the boat

Nautical Terms – Boating Words Every Sailor Should Know

What are nautical terms.

I can still remember going on a boat trip with a friend who was a sailor and a boat expert. He kept mentioning these strange words to his assistant while trying to control the boat. I had almost lost my interest in sailing until my friend walked over and had to put me out of my misery. For the first time, I heard the nautical phrase terms, i.e., a vocabulary for the boat or terms used when sailing.

Better still you might want to ask most simply, what are nautical terms???

Nautical terms are also known as sailing terms. They are listings of various words associated with ships, boats, and sailing. It’s the same way we use catering terms when catering and scientific terms when writing or describing an object in science.

Funny Nautical Terms

In as much as sailing can be educative, it can also be humorous. I thought I had heard it all but telling me the nautical terms were wasn’t enough when my friend began using these hilarious terms over and over. I could remember myself bursting into a long-term of laughter whenever he mentioned the word “poop deck” or when he described the toilet of the boat as the head.

I took the time to note down the following funny nautical terms; I am sure they will get you giggling soon:

  • Abreast : Used when two boats lay together in a way the bible would probably frown at.
  • Poop deck : You should be thinking of the rest-room, but it’s not, it’s just the part of the boat you get to roam about freely, it’s a standard rude term used in boating.
  • Jacob’s ladder : Now this is supposed to be the title of a famous movie I once saw at the cinema, but in this case, it’s just a rope ladder.
  • Screw : This is talking about the propeller.
  • Ground tackle : Sounds like a term used in sport, but it’s just another hilarious term for the anchor and associated bits and bobs.
  • Porthole : It merely means “I’m having a panic attack.”
  • Flange : I am scared.

Common Nautical Terms

Away from the humor, if you are looking to become an expert in boating or sailing, or you want the sailing education, then you must try to get familiar with some common nautical terms. Knowing these terms will make it easier to communicate with people aboard the ship. The essence is neither to boast nor impress your friends but helps to stay safe on water especially during an emergency when you might have to take sets of instructions using these terminologies.

Here are some common nautical terms:

  • Bow : This refers to the front end of the boat.
  • Forward : This is used when you are moving toward the front end of the boat [bow].
  • Aft : Used to describe your movement towards the rear end of the boat, more like saying someone is going “aft.”
  • Ahead : Refers to the movement of a boat in a forward direction.
  • Astern : Refers to the backward movement of a boat.
  • Topside : Moving from the lower deck of the boat to the upper deck of the ship.
  • Amidships : Refers to the central part of a boating vessel.
  • Port Quarter : This is the rear left side of the boat.
  • Starboard Quarter : Refers to the rear right of the boat.
  • Port Bow : This is the front left side of the boat.

  • Port : When standing at the rear of the boat and looking forward, the port is the entire left side of the ship.
  • Leeward : This is also known as “Lee,” it’s the direction opposite to the movement of the wind.
  • Windward : This is the direction in which the wind is currently blowing; it is the opposite of “lee.” Sailboats usually move in the direction of the wind, and this makes it an essential term to note.
  • Boom : The boom is the horizontal pole which extends from the bottom of the mast, manipulating the boom to the direction of the wind helps the boat to harness the power of the wind for forwarding or backward movement.
  • Stern : This is the rear end of the boat.
  • Underway : A boat is referred to as being “underway’ when it is moving, either by a motor or by the energy provided by the wind.
