Why Can’t Catamarans Sail Upwind Efficiently? (Performance Tips)

Posted on June 1, 2022

For us cat enthusiasts, by the way, I mean catamaran(no offense to current cat lovers), our boat can do no wrong. We’ll argue a monohull vessel owner to death about the stability, speed, space, comfort, privacy, safety, huge galley, and more of our boat. Did I mention reduced seasickness?

However, whenever the topic of upwind arises, our voices tend to lower a bit. After all, not every cat except for performance cruising ones can rise to the challenge of going higher into the wind. It is especially annoying for those who’ve transitioned from yachts to the open-sea sailing experience. So, why do cats struggle upwind?

There are three reasons that catamarans can’t sail upwind efficiently. First is lateral resistance, then apparent wind generation, and last but not least, our sheeting angle. These can prove to aggravate blue water voyagers, but fortunately, they’re fixable. 

Below are the reasons for cats’ upwind flaws and ways around them. Let’s continue reading!

Why Can’t Catamarans Sail Upwind Efficiently?

1. lateral resistance.

When you have a less underwater surface area to push the force generated by the sails against, your boat will go sideways. Lateral resistance means less weight in the water, which enhances speed.

In upwind or even light wind sailing circumstances , it can be more difficult to gain ground. You may not be able to detect whether you’re overpowered because your boat doesn’t seem to “respond” in the same way as the wind.

In bad weather, a cat can prove dangerous, but with proper instructions, it can be steered safely.

2. Apparent Wind Generation

Due to reduced overall weight plus less wetted surface, a cat will develop more apparent wind than its single hull counterpart while moving due to less drag. 

There will be less of a chance that the vessel will be able to cruise as near as possible to the prevailing wind if it is moving at a high rate of speed.

3. The Sheeting Angle

Multihulls should have a broader overall angle from the centerline of any sail attachment to the aft point of attachment because of the first and second points made earlier. 

The higher a cat will point, the smaller the angle must be. When you’re working with a large amount of underwater surface region on a monohull, you can achieve this level of efficiency. However, on a multi-hull, it doesn’t work as well.

How to Improve a Cat’s Upwind Performance

Catamarans are notoriously difficult to sail upwind because of their strong pitching moment , which can be reduced by obtaining a carbon fiber mast along with high-tech shrouds that are both lighter and stiffer.

There are expensive, custom-built, fully rotating rigs available that allow you to point your mast directly into an apparent wind’s “eye.” With Mylar or Kevlar, you may improve your sails from Dacron to a considerably stiffer one that will not deform under the enormous stresses a catamaran faces while sailing upwind.

Buy a Cat That Comes With Daggerboards

Taking all of the above four techniques to improve upwind performance in a cruising cat is, of course, extremely expensive. However, I believe that a high-end pair of high-tech sails and daggerboards offers the best value for your money. Naturally, if you are a serious sailor or racer, you’ll go through all four procedures to build a real rocket ship. 

If you’re a sailmaker, I’ll let you know what materials to use, what type of battens to use, and how to cut the sail for maximum upwind performance. There are many misconceptions in the catamaran industry about the merits and cons of daggerboards and fixed keels for cruising sailors. Therefore, here I’ll focus on the advantages and disadvantages of each.

Daggerboard Pros

When sailing into the wind, a cat with a daggerboard will always sail higher and will have less leeway than a boat with a fixed keel. It is much easier to get away from a lee shore or go toward an upwind destination with this increased pointing ability and decreased leeway when cruising. It is a fact of life on the high seas that there are times when you cannot seek shelter.

All things being equal, a cat with daggerboards could sail upward of 2 knots quicker than a catamaran with keels, since it doesn’t bear the tremendous fixed hydrodynamic drag of two deep and lengthy fixed keels. Long-distance cruising benefits greatly from this extra speed. 

In addition to decreasing exposure to severe weather, efficient weather routing makes it easier to either run away from or completely escape adverse weather. When sailing, a speedier boat always gives the cruising party more alternatives and, consequently, more safety. 

When compared to a cat with keels, a daggerboard cat often draws just over two times as much water. As a result, cats having daggerboards can access a much wider range of sailing grounds and anchorages than a keel cat does. 

Daggerboards allow the helmsman to fine-tune his catamaran’s balance in exceptionally rough seas by lifting and lowering the boards.

When sailing in large cross-seas, we typically lift the leeward daggerboard fully and drop the other board midway to avoid being tripped up by a breaking wave. In storm-force circumstances with enormous breaking cross seas, a keel cat is unable to avoid “tripping over herself” because the keels are always lowered.

The lower wetted surface area of a catamaran having fully elevated daggerboards makes it faster off the wind. More importantly, a cat with lifted boards out of the wind may turn in astonishingly tight circles. 

Downwind surfing aboard a daggerboard cat is the ultimate thrill for true sailors; the cat appears free with its boards fully up. There’s no way to get away from the keeled cat, who’s always on the train track.

Daggerboard Cons

A shipyard’s daggerboards can rattle if they are not properly placed. This irritates me. It’s unlikely that a well-built cat will have this problem.

If you don’t pay attention while sailing in shallow waters, and one of your daggerboards is in the down position, you will shatter it if you hit a hard reef at fast speed. As long as the shattered board is raised, you can simply sail away. 

We have some terrible news for you: A new board will set you back roughly $8,000. When it comes to keel cats, you’d have to remove the yacht and have the keel fixed at a shipyard if you were to get a hard grounding. 

A daggerboard replacement does not necessitate hauling the yacht or relying on a shipyard to fix fiberglass. All things considered, repairing a fixed keel is likely to be a few thousand dollars less expensive than repairing a costly vacuum-packed foam composite daggerboard.

Keeping the boards down, you are more likely to break just one board if you run into something out at sea. Sailing upwind is possible even with one shattered daggerboard because the intact one may be lowered. 

A single daggerboard cat still outpoints a keeled cat (in terms of point totals). Each hull loses a small amount of interior space because of daggerboard trunks.

Daggerboard Costs

Building daggerboards is quite expensive. With the help of winches and pulleys, a builder must manufacture two daggerboards and their trunks. Building a cat that’s 45 feet with two daggerboards costs between $30,000 and $50,000 more than without them. As a result, cats having daggerboards will always cost more.

Which Cats Shouldn’t Use Daggerboards?

Because bareboat sailors frequently go aground, daggerboard cats are not suited for bareboat chartering. A few “Painkillers” later, they’ll forget to raise the daggerboard, which leads to broken daggerboards. 

Even after being instructed to do so. There is no use in wasting money on an expensive choice that is likely to break charter sailors.

Can’t Afford Daggerboards?

To make the most of your next blue water excursion, here are some helpful hints:

• Upwind, a catamaran will not be as quick as a monohull.
• Stay on top of your game.
• Use your chart plotter, follow the lead of neighboring vessels, and trust your gut sense.
• Ensure that the jib cars are in the best possible positions.
• The more gasoline you save by sailing better upwind, the better off you’ll be.

How to Sail Upwind (Against the Wind)?

Sailing upwind is perhaps one of the most misunderstood aspect of sailing for most beginners.

The wind, this invisible force, personified and divinized in mythology and religion, has been harnessed throughout human history, but going against it is somehow harder to grasp intellectually than it actually is.

Not surprisingly, one of the first sailing fundamentals you learn when you are new to this world is therefore upwind sailing . 

What does this mean? How does a yacht sail upwind? Read on and you will understand this obscure concept.

What is upwind sailing? 

Let’s start with a simple and short definition: upwind is when going against the wind.

However, you do not directly go against the wind. That is physically impossible, as you may have already guessed.

“Sailing upwind” means sailing as close to the direction the wind is blowing from as possible. In a word, about 45 degrees away, left or right, from the apparent wind’s direction. You are not going against the exact direction of the wind, but you can move forward against the wind without directly facing it.

What happens if you cross this imaginary line steering the boat closer into the direction of the wind? The sails start to flap around and the boat slows down.

As an old sea-dogs once said: “flapping sail, unhappy sail!” Or something like that.

The main differences between sailing upwind and downwind

While sailing upwind means going against the wind, sailing downwind is going with the wind. It is simply the opposite.

Obviously, sailing downwind is much easier than sailing upwind. If the sailing concept of upwind and downwind is still obscure to you, try with a bicycle and you should quickly understand.

Another important difference involves how the boat is steered and the sails trimmed when going downwind or upwind. 

Going upwind, one generally pulls the sails all the way in and then uses them as a guide to steer the boat.  When sailing downwind, one usually aims the boat straight to the desired course, and then uses this heading as a guide for how to trim the sails. Upwind sails work like airplane wings. They are trimmed to give lift. Downwind, the air is behind the sails, and they drive the boat by filling and pulling it.

Let’s have a look at how sailing upwind is actually performed while sailing.

Tacking: the main upwind sailing tactic

As we have seen above, sailing upwind means sailing towards the general wind direction but not directly into the wind; the sails would flutter and the boat would stop. Instead, sailors use a zigzag motion with moving the bow of the boat, left and right, through the wind in order to make headway.  This tactic is called “ tacking ”. 

This sounds a very simple thing to do but, in fact, it is tough to be good at. This requires some cooperation from the crew and commands will keep everyone working together. Tacking is teamwork and strength lies in numbers! 

Let’s continue with the essential vocabulary mastery. A series of tacking moves, in a zig-zag pattern, is called beating . The opposite manoeuvre to tacking is called jibing . A jibe consists in turning the stern of the boat through the wind so that the wind changes from one side of the boat to the other side. It allows sailing upwind in the desired direction.

When facing the wind and its various caprices, the art of sailing is real choreography! 

How to tack a sailing yacht to sail upwind (against the wind)

Let’s now get to the heart of the matter: the technical aspect of tacking a sailing yacht to sail upwind.

First things first

A good communication and a coordinated team are a must when tacking a sailing boat.  To follow, the different steps of the process but before a brief glossary of the key terms.

Port and starboard refer to the left and right side of the vessel, not the observer. 

Port Tack : port tack is when the wind is blowing from the port side (left) of the vessel.

Starboard Tack : a boat is on a starboard tack if the wind is coming over the starboard (right) side of boat with sails on port (left) side.

Jib Sheets : ropes and lines to trim or “sheet” the jib.

Working sheet: jib sheets that are actively trimming the jib. They are tight on to the clue and pull out and trim the jib sail.

Lazy sheet : jib sheets ropes that are unused momentarily.

Main sheet : Rope that is attached to the boom and is used to control the mainsail.

How to tack a sailboat properly in 10 Steps

1- The skipper makes sure that the new course is clear.

2- If that is the case, he shouts “ Ready about ” to the crew members to be ready. The perfect translation of “ Ready about ” would be ” before I throw the helm over, are you ready to let go of the old jib sheet, trim in the new and move to the other side? ».

2- He now waits for them to prepare the sheets and lines for managing the sails.

4- In the meantime, the skipper estimates the lay line, that is to say where the boat is going to be pointing after the tack. When sailing upwind the lay line is generally 90 degrees to your left or right from where you stand now. This step is essential.

5- When the skipper hears “ Ready ” or “ All clear ” from the crew, he responds “ helm to lee ” to notify the crew that he is about to start the tacking manoeuvre by turning the steering either to portside or starboard side. When the wind starts blowing the jib to the lazy-sheet, it is the time to stop turning.

6- Then, with calling Lee-Ho  or  Hard-a-Lee , the skipper announces he is turning the boat towards the wind. The vessel is tacking. As the headsail starts to flap, the crew on the working sheet eases and releases the sheet from the winch.

7-At this stage the wind will have switched sides and is now blowing to the other side of the sails. This is the time when the crew moves to the other side of the sailboat. This point is crucial for the balance of the vessel. 

8- The boat continues to turn through wind and the jib blows across to the new side, flapping a little as it goes.

9- This is the good time for the crew on winch to pull in the new working sheet and start pulling in the line on the lazy sheet (now being working sheet) on the other side. The main sheet needs to be tightened in the centre of the boat. 

10- The sailboat starts to pick up speed at about 90 degrees off from the original course. The skipper keeps the tiller in the middle. The crew starts to trim and adjust the sail. The tack has been successfully performed!

Tacking to sail upwind with a monohull vs tacking with a multihull

The operations of sailing a multihull and a monohull are basically the same. Almost.

One of the main differences is actually in tacking, so in sailing upwind.

A monohull, much easier to manoeuvre, will tack quickly and is faster to respond to the helm than a multihull.

Conversely, tacking with a multihull can be quite challenging. Because of its lighter weight, wider beam and windage, the multihull will suddendly slow whereas the tacking requires a sufficient speed not to lose too much forward momentum.

Therefore, turning through the wind will be more hesitant than on a ballasted monohull, which carries its momentum through the wind. 

Tacking with a monohull vs tacking with a multihull: a clear advantage for monohull!

That’s it, you know everything there is to know about sailing upwind. If you are unsure about how to sail against the wind, you can always charter a yacht with an experienced crew or skipper and see how it’s done pratically.

Catamaran Sailing Techniques Part 5: sailing a cat downwind – with Nigel Irens

• Matthew Sheahan
• December 12, 2015

Choice of sails and an awareness of your VMG are important when sailing a catamaran downwind, says Nigels Irens

The right strategy for getting the best performance out of a catamaran downwind will depend very much on the speed potential built into the multihull you are sailing.

A bit of background here: any boat that sails slowly, irrespective of how many hulls it has, needs to set lots of sail area and sail deep downwind if it is to achieve a decent speed made good (VMG) – ie typically between 160° and 170° – or within 10-20° of the dead downwind line if you prefer.

Whether you are aboard a monohull or multihull, sailing dead downwind doesn’t usually work well in terms of VMG – mainly because in that condition apparent wind speed (AWS) is limited to true wind speed (TWS) minus your boat speed over the ground (SOG) so it is impossible to generate any apparent wind – as you go faster you simply sail away from it.

Wind shadow

Another problem is that sails tend to shadow one another on this course so it’s hard, for example, to get much help from a foresail that is in the wind shadow of the mainsail.

As it happens, this dead downwind course will also mean that you are running a permanent risk of an accidental gybe – particularly in any kind of seaway, although in a catamaran at least you won’t have the cyclic rolling problem that conventional single-hulled boats suffer from if they sail too deep downwind.

Keeping the main under control through the gybe is important, especially as many modern cruising mainsails are fully battened and have plenty of sail area

So assuming your catamaran is a bread-and-butter cruiser, without much performance capability, you’ll be doing much as you would do in an equivalent monohull, which is setting either a conventional symmetrical spinnaker or perhaps an asymmetric one.

Symmetric spinnaker

The symmetric one has the advantage that when you gybe there’s not much to do as the flow is simply reversed across the sail on the other gybe. On the other hand, to make the most of that sail you’d really need to set a conventional spinnaker pole – as seen on single-hulled boats of limited speed capability – and that means swapping the pole to the other side as you go through the gybe.

In reality, you don’t see many spinnaker poles on catamarans flying symmetrical spinnakers. When gybing, most people simply haul the new tack down to the new windward bow and allow the old tack to be drawn back by the new sheet on the new leeward side.

In practice, this arrangement works less well than you might hope, mainly because if the tack of the sail is to be able to function as a clew on the other gybe, then it needs to be cut quite high.

On the other hand when that corner of the sail is working as a tack it would work better if it was lower – and so able to be drawn right out to the windward bow.

Asymmetric spinnaker

For this reason most modern catamarans choose to fly an asymmetric spinnaker and tack it to the weather bow. If you go down this route and because it is asymmetric, you need to turn the sail inside out when you gybe.

Over the years sailmakers have managed to design these asymmetric sails so that they have more volume aloft, so that even when you are sailing quite deep angles the luff of the sail is setting well to windward (a bit like a kite) and so is able to ‘grab’ more wind that would have passed to windward of the boat and draw it across the sail from windward to leeward.

This configuration is pretty much as good as it gets for a cruising catamaran and a sail like this might be good for a range of apparent wind angles of between 160-90°.

Gennaker or screecher

The faster a boat sails, the more time it spends with the apparent wind forward of the beam, 90° or less. As a result, the standard downwind sail used by a true race boat, called a gennaker or screecher (US), looks more like a big jib. The faster the boat, the flatter the sail is cut. An iceboat – which is faster than anything on the draggy old water – sails with a single ‘mainsail’ which you’ll see set as flat as a board on all points of sailing.

Back in the domain of cruising catamarans these big downwind sails have a lot going for them because the beauty of any sail set forward of the mast is that if there should be a sudden wind increase the sheet can be released and the sail allowed to depower by streaming downwind.

That means that when on passage a cruising catamaran can always be rendered safe if things get a little out of hand. All being well it can be ‘snuffed’ – ideally while in the lee of the mainsail.

Unstable weather

If the weather is a bit unpredictable – perhaps there is a threat of tropical line squalls around, for example – then an experienced catamaran skipper might think of keeping average speeds up by using an asymmetric spinnaker while taking a reef or two in the mainsail. The latter can neither be dumped nor lowered if the boat is caught in sudden squall from abaft the beam.

Few cats have vangs, which means that the twist in the main is controlled by the mainsheet and traveller – if you have one

All would be well if you could turn the catamaran round head to wind to take in a reef if such a squall struck unexpectedly – perhaps at night – but the danger is that it may already be too late to round up in those conditions without the ability to depower that big mainsail through dumping the sheet or lowering the sail.

More will be said later on in this series about the safety issues that arise when cruising in a catamaran.

Do’s and don’ts

• DO get good advice from a catamaran-savvy sailmaker with regard to the choice of sails to match your cruising plans.
• DO keep abreast of what other catamaran sailors have learned over the years. Pooling experience makes sense and online forums help spread the word.
• DO try to put some time in on a beach cat in order to get used to the way a catamaran works. If you can handle one of those with confidence you should have no problem with a cruising cat.
• DON’T leave a full main up if cruising downwind in unstable weather – set a sail that’s flown ahead of the mast instead, it’s easier to lower or reef if the breeze builds.
• DON’T overlook the need to practise sail handling/changes in relatively benign conditions before having to perform them for real in a blow.
• DON’T forget the importance of prioritising VMG towards your destination. If the boat you are sailing is a faster multihull the longer route may well be the shortest in elapsed time.

Part 6: Coping with heavy weather

Series author: nigel irens.

One name stands out when you think of multihull design: the British designer Nigel Irens.

His career began when he studied Boatyard Management at what is now Solent University before opening a sailing school in Bristol and later moving to a multihull yard. He and a friend, Mark Pridie, won their class in the 1978 Round Britain race in a salvaged Dick Newick-designed 31-footer. Later, in 1985, he won the Round Britain Race with Tony Bullimore with whom he was jointly awarded Yachtsman of the Year.

His first major design success came in 1984 when his 80ft LOA catamaran Formule Tag set a new 24-hour run, clocking 518 miles. During the 1990s it was his designs that were dominant on the racecourse: Mike Birch’s Fujicolour , Philippe Poupon’s Fleury Michon VIII , Tony Bullimore’s Apricot . Most famous of all was Ellen MacArthur’s 75ft trimaran B&Q, which beat the solo round the world record in 2005.

His designs have included cruising and racing boats, powerboats and monohulls, but it is multis he is best known for.

How to sail UPWIND in your catamaran

Introduction

In this episode, we talk about sailing upwind in a catamaran. So why do catamarans have a reputation for sailing upwind so badly? Are daggerboards really necessary in order to reach some reasonable upwind angles?

The good news is for those of you sporting a breed of cat that doesn’t have a couple of daggerboards intruding into your living space you can still get your boat to go to windward. While daggerboards do provide some extra grip in the water compared to the keeled hulls of most charter variety catamarans, they are not the key secret to success. Let’s dive into what are the key critical ingredients to make a multihull successfully sail upwind.

The Headsail

The most important ingredient for upwind performance are your working sails. That means, your mainsail and your headsail (or jib). Having the correct sail profiles are critical to upwind performance. This is why most racing boats will have sail stripes on their sails. Sail stripes help to visually identify the shape of your sail. On a catamaran, you are chasing relatively flat sails. The sail stripes will help you identify the fullness of your sail. You can use sail stripes on both the mainsail and headsail.

As certain sail clothes age and are used they will stretch and lose shape. This can impact drastically on your vessel’s performance.

The other aspect to consider is that forestay tension can also affect the shape of your headsail. The tighter the forestay tension, the more stable the sail shape will be. A loose forestay means that there will be more shape in your headsail depending if you are at the top of the wave or the bottom.

You can only sail as far upwind as your entry angle of the jib will let you. If your jib is too full, in other words your headsail has a lot of shape in it, you are never going to fill the sail correctly to be able to sail at 30 degrees apparent.

Sheeting Angles

The exit slot for the headsail is the space between the clew of the jib and the mainsail. This exit slot must be sheeted at the correct angle to allow maximum efficiency. We can reduce the exit slot gap on our headsail to improve our sail efficiency and sail closer upwind.

The Mainsail

We also use the speed stripes on our mainsail to help analyse shape and twist in the main. Along with these visual cues, we use specialized software to tell how full, or how flat, what the draft etc to give us additional data on our sails. You will notice that the sails on Paikea on quite flat, this shape is important to help us go upwind.

The Instruments

It is important to note that when sailing upwind, the Apparent Wind Speed or AWS will be more than the True Wind Speed or TWS. This means that your sails will be feeling more wind than is actually on the water.

Only 1 Rudder

Because we only have one rudder at the moment, we need to keep the speed up in order for it to be effective in the water. We drop the traveler to reduce the load on our remaining rudder which makes us go faster. Shayne also takes this opportunity to mumble about his traveler system again!!

Shaking out a Reef

Now we have more sail area at reef 3, we can go a bit faster. If we go too slow both our rudder and daggerboards are less effective. We try and keep Paikea sailing at 8kts upwind in order to balance the boat and keep the loads off the rudder. The extra bonus is that with the extra sail area we are able to keep the boat speeds

Mast Rotation

In order to increase upwind performance further, we can rotate our carbon wing mast. We can get a lot more height and speed when we rotate the mast. At this stage, we do not do this often as we don’t have a mast rotation sensor on the mast and it end up messing with all our instruments and data collection. We are still building polars and so need to make sure that the data we are collecting is as accurate as we can make it.

Choosing the Right Catamaran

When it comes to choosing the right catamaran for your sailing adventures, there are a few key factors to consider. The hull type, size, capacity, and performance versus cruising capabilities all play a crucial role in finding the perfect catamaran for your needs.

Catamarans come in various hull types, each with its own set of advantages and disadvantages. The most common hull types are solid, balsa core, foam core, and carbon. Solid hulls offer durability and strength but may be heavier and less fuel-efficient. Balsa core hulls provide good insulation and strength-to-weight ratio, while foam core hulls offer excellent buoyancy and lightness. Carbon hulls are the most lightweight and rigid but come with a higher price tag.

When choosing the right hull type, consider factors such as your sailing style, budget, and desired performance. It’s essential to understand the pros and cons of each hull type to make an informed decision.

Size and Capacity

The size and capacity of a catamaran are crucial considerations, depending on your sailing goals. Smaller catamarans, typically between 30 to 40 feet, are easier to handle and navigate, making them ideal for solo sailors or those new to catamaran sailing. On the other hand, larger catamarans, ranging from 40 to 60 feet or more, offer ample space for accommodation, amenities, and extended trips.

Consider the number of people you plan to sail with and the amount of storage and living space you require. It’s important to strike a balance between comfort and maneuverability when choosing the size and capacity of your catamaran.

Performance vs. Cruising

Another essential factor to consider when choosing a catamaran is whether you prioritize performance or cruising capabilities. Performance catamarans are designed for speed and agility, featuring lightweight construction, tall rigs, and high-tech materials. They provide exhilarating sailing experiences but might sacrifice some comfort and amenities.

Cruising catamarans, on the other hand, offer spacious living areas, numerous amenities, and stability. They prioritize comfort and leisure, making them perfect for extended trips and living aboard. However, they may not have the same speed and maneuverability as performance-oriented catamarans.

Consider your sailing goals and preferences to determine whether you prioritize performance or cruising capabilities. Consulting with experienced catamaran sailors or attending boat shows can also provide valuable insights into finding the right balance between the two.

Understanding Catamaran Rigging

To fully grasp the ins and outs of catamaran sailing, it’s important to understand the various components of catamaran rigging. From the mast and boom to the sails, standing rigging, and running rigging, each element plays a crucial role in the performance and handling of the catamaran.

Mast and Boom

The mast and boom act as the backbone of the catamaran rigging system. The mast supports the sails and facilitates their proper functioning, while the boom controls the shape and tension of the main sail. It’s essential to choose a mast and boom that are suitable for your catamaran’s size, sailing style, and intended use.

Consider factors such as material construction, height, and compatibility with the sails when selecting the right mast and boom. Consulting with rigging professionals or experienced catamaran sailors can provide valuable guidance in making an informed decision.

Sails are one of the most crucial components of catamaran rigging, as they harness the power of the wind and propel the catamaran forward. The main sail, genoa or jib, and spinnakers are the primary types of sails used in catamaran sailing.

The main sail is the largest and most important sail, responsible for driving the catamaran forward. The genoa or jib is a smaller headsail that complements the main sail, providing additional power and maneuverability. Spinnakers are specialized downwind sails that excel in light wind conditions.

Choosing the right sails involves considering factors such as sail material, size, and shape to suit your catamaran’s rigging and sailing goals. Working closely with sailmakers or experienced catamaran sailors can help ensure you select the most suitable sails for your catamaran.

Standing Rigging

Standing rigging refers to the fixed components of the catamaran’s rigging system that support the mast and provide stability. This includes elements such as stays, shrouds, and rigging wires.

It’s crucial to regularly inspect and maintain the standing rigging to ensure its structural integrity and minimize the risk of failure. Look for signs of wear and tear, corrosion, or any loose fittings that need immediate attention. Consulting with rigging professionals or experienced catamaran sailors can help you develop a comprehensive maintenance routine for your standing rigging.

Running Rigging

Running rigging refers to the adjustable components of the catamaran’s rigging system that control sail shape and trim. This includes elements such as halyards, sheets, and control lines.

Understanding how to properly trim and adjust the running rigging is essential for optimal sail performance and handling. Familiarize yourself with the purpose and function of each line, learning how to adjust them for different sailing conditions and maneuvers. Practice and experimentation will help you develop the necessary skills to make the most of your catamaran’s running rigging.

Essential Equipment for Catamaran Sailing

When setting sail on a catamaran, having the right equipment on board is crucial for a safe and enjoyable experience. From navigation instruments to safety equipment, anchoring gear, and communication devices, each item serves a specific purpose in enhancing your sailing journey.

Sailing a catamaran

If the wind is strong enough to lift the windward hull, a catamaran will always sail on the apparent wind—meaning that speed forward through the water tightens the angle of the wind so that it always appears to be blowing from ahead, irrespective of the course sailed.

SAIL FREE AND FAST

The principal requirement of catamaran sailing is to build up apparent wind. When beating upwind, do not try to sail as close to the wind as possible, as with a conventional dinghy . Instead, bear off a few degrees to power up the rig's forward drive. Increased speed will more than compensate for lack of pointing.

Like any boat, a catamaran is at its fastest on a reach. On a run, with airflow over one side of the sails only, and both hulls down in the water, a catamaran is slow. To compensate, catamaran sailors

Sailing downwind on a three-sail reach, the mainsail is sheeted almost on the centerline due to the apparent wind angle and the speed of the catamaran. The helmsman keeps maximum control by holding the tiller bar and letting the tiller extension trail.

should "tack downwind." Start on a beam reach and head up toward the wind to build up power, lift the windward hull, and increase speed. The result is that the apparent wind direction moves ahead and the helmsman can bear away downwind, still sailing at speed and keeping the hull flying. If the speed decreases and the windward hull drops, he will head up toward the wind, then bear away again, with a succession of jibes taking the boat to a point dead downwind. A catamaran that "tacks" downwind will sail considerably farther than one sailing on a dead run, but owing to far greater speed will always reach a downwind point first.

SAILING A CATAMARAN 145

POINTS OF SAILING

Catamaran sailors should beat to windward on a close reach, not attempting to point high upwind, which slows the boat and prevents the windward hull lifting. Running is also inefficient, except in light winds. Sail a succession of port and starboard broad reaches, jibing across the downwind course. Center the mainsheet for upwind sailing; ease it down the track downwind.

Readers' Questions

How close on a reach catamaran?

On a Reach catamaran, the distance between the two hulls is usually quite close. The width of the catamaran can vary depending on the specific model and size, but typically the hulls are placed closer together compared to other types of catamarans. This design allows for better stability and maneuverability, especially when sailing on a reach (a point of sail where the wind is coming from the side of the boat). The close proximity of the hulls also increases the overall deck space available on the catamaran.

Why don't a catamaran sail closer to the wind?

A catamaran is a type of boat with two parallel hulls, and it is known for its stability and speed. However, one limitation of catamarans is their ability to sail as close to the wind (into the wind) compared to other sailboats such as monohulls. There are a few reasons why catamarans cannot sail as close to the wind: High windage: Catamarans have a wider beam (the width of the boat) due to their double-hull design. This results in more surface area exposed to the wind, causing a higher windage. The wind pushing against the larger surface area makes it harder for the boat to point directly into the wind and maintain forward progress. Limited upwind performance: Catamarans are usually designed with larger and flatter hulls, which provide buoyancy and stability. However, these hull shapes create more drag and resist the boat's ability to sail upwind efficiently. They are not optimized for pointing directly into the wind. Lack of keel: Unlike monohull sailboats, catamarans do not have a deep keel extending below the waterline. Keels provide lateral resistance and prevent sideways slipping or skidding. This lack of keel reduces the ability of catamarans to sail upwind effectively. However, it's important to note that modern catamarans have made significant advancements in their upwind performance through design modifications and technological improvements. Newer models may have features like daggerboards or centerboards to enhance lift and lateral resistance, allowing them to sail closer to the wind compared to older designs.

How to sail a catamaran dinghy fast downwind?

Tune your rig: Make sure your sails are set correctly and the rigging is properly tensioned. Carefully trim the sails: Sheet in or out your mainsail and jib as needed to keep them filling in the wind as you make your course downwind. Center your weight: Sit in the middle of the cockpit and make sure your crew’s weight is evenly distributed. Keep the bow up: Heel the boat slightly to keep the bow from plunging into the waves. Maintain a smooth ride: Trim the sails to adjust the speed and angle of your course. Ride the waves: As you go downwind, find the best angle of attack by riding on the crest of the waves. Use the wind to your advantage: As the wind changes direction or intensity, adjust your sail trim accordingly to get the most speed.

In this article, I list many of the things that I have found significant about sailing a catamaran. The list is mainly aimed towards sailors transitioning from monohulls, but new sailors without prior experience will benefit from reading this before leaving harbor!

So what do you need to know before setting off in a Catamaran?

Catamarans Don’t Heel

Since catamarans have two hulls, the boat won’t heel over to its side while sailing; this means a ton of things! In part, it means that your ride will be faster, safer, more comfortable, etc.

Read this  to understand the difference between monohulls (aka regular sailboats) and catamarans.

You will be faster on a Catamaran.

Since a catamaran has two hulls, it has less volume of the boat below the surface; this means less drag and higher speeds.

Want to know why cats are faster than other boats?

Maneuverability inside the Marina will be much more pleasant.

Although a catamaran will be more affected by winds due to its immense size, you can maneuver it as you would with a battle tank since it has two engines. That is doing a 360 turn without any movement forward or backward. This is an excellent way to enter and exit a marina.

Fuel costs will decrease.

Low drag means less energy needed to propel the boat; this is also true when running the engines. Compared to a monohull, the catamaran will draw less fuel.

Check out this article  to understand why and how you can save fuel and instead spend your money on fun things!

If you get knocked over, you won’t get back up again (but at least you won’t sink!)

Catamarans have a terrible reputation for flipping over or capsizing as it is known to the people of the water. There is not much data to support that claim, and if you look at the available data, you would actually see that catamarans, in many ways, are safer than boats with only one hull.

Are catamarans safer than other sailboats?

Catamarans are wider and, therefore, safer.

Is it easier to push something to its side if it has a wide or a small base? Yepp exactly, the cat has a broad base and is, therefore, more stable (the short and easy explanation). There are numerous other factors to consider but a wider base means better stability!

Catamarans will get you the ladies(or men, or cats, or whatever)

There is nothing more accurate on this list than the fact that a catamaran will get you more company, of the sort you prefer, than a monohull. The sailing is smoother; the space is plentiful, it’s basically made for having friends hanging out on the trampolines.

Speaking of trampolines, some myths say that they are made to reduce water onboard and enhance safety, but everybody really knows it’s a place for beautiful times with great friends ;)!

What are  trampolines  you say?

Because of the shallow draft, you can go places where monohulls can’t

If you are going to the Bahamas (or any other place where the water isn’t very deep), and believe me, you definitely want, then a shallow draft is almost as good of a friend as a cold beer on a sunny day.

A shallow draft means that your boat won’t be sticking very deep into the water, which significantly enhances the number of places you can explore, and it also makes it possible to get very close to the beach.

Be prepared to spend your dollars.

“A boat is a hole in the water where you throw your money” is what a wise friend of mine once told me in a marina in the Miami River. Little did I know at the time how true that statement was to become.

And if you’re on a catamaran… you will have two engines, larger sails, more surface area, more everything, and more everything means that more things will break and more items will have to be paid for

BUT! it also means more fun!

Finding a place to lift your cat out of the water might be trickier than you thought.

Unless you are on a smaller cat, such as the Gemini Legacy 35, you won’t be able to fit in a standard slip, and getting hauled up out of the water might not be possible everywhere.

Be prepared to pay a little extra, and make sure you ask before you!

In contrary to many beliefs, cats can be sailed single-handed.

Another myth is that catamarans are harder to sail than their monohull counterpart; this is simply not true in a general sense. If the boat is set up for shorthanded sailing, it will most certainly be easier to sail than its heeling and leaning sister ship, the monohull.

If you are interested in the skills needed to handle a large cruising catamaran I think you should check out my recommended books here.

No more sailing close to the wind

Since a cat doesn’t have a colossal keel, it tends to move sideways when sailing close to the point of wind. This means more drag, less transfer of movement in the direction of travel, and a less comfortable trip.

Usually, a cat needs to sail more of the wind than a monohull,

Downwind is your new best friend.

But on the other hand, going downwind or running downwind is, together with humans, your dog and red wine, your new best friend. This is where the catamaran will show its true potential.

It’s fast, smooth, and can take you around the world!

Sailing around the world.

Unless you are setting a world record, you will probably take the westward route around the globe. Sailing west means traveling with the prevailing winds and, you guessed it, perfect for a catamaran.

Interested in sailing around the world?

You have friends? Bring all of them!

Maybe not all, but many catamarans can fit many people; 6-10 people is not uncommon. Most of the space is on deck, but since there are two hulls, there are usually 2-4 berths fitting 4-8 people sleeping!

That’s a lot of friends, family, cats, or whomever you would want to bring.

Are you used to monohulls? Then you need to update your storm tactics!

Often, the boat will survive more hardship than the crew; it has happened more than once that a ship will be found only to have lost its team somewhere in the middle of the ocean.

A boat is only as good as its captain allows it to become; with poor sailing skills comes danger, and handling a catamaran IS different than handling another type of boat. Ensure you update your skillset, especially those considering rough weather, so that they are relevant when transitioning to a different kind of vessel!

Full speed with double engines

Exactly how fast you will be able to travel is, of course, dependent upon many factors. But something you can rely on is that more power equals higher speeds; in most catamarans, they employ two engines!

If you want to see a table of examples comparing sailing with one engine and two engines,  check this out.

Hate swinging around on anchor? You better up your bridle-game

A well-balanced bridle will make the cat stay stable towards the wind; a poorly balanced bridle will tend to do a pendulum motion where the waves might push it one way only for the wind to push it back.

Want to better understand  how a bridle work and how to make one?

Don’t stop before the beach; go all the way upon it.

Sailing in the Caribbean, we could often find ourselves wanting to explore a deserted island. We could either throw in the dingy or swim to shore; with a catamaran, you have a third option: “beach” it.

Beaching a catamaran means taking it all the way up to the shoreline so you can step off onto a beautiful beach without even getting your toes wet!

Check this  out to understand what beaching a catamaran is like.

The cat is enormous; why not live on it!

A monohull’s size is usually what takes the fun and comfort out of the vacation, but with more space and your own berth/room, the ability to stay comfortably for more extended periods increases.

You might even have a hard time to get people of your boat 😉

How to sail faster upwind than a longer monohull

Yes, it is usually true that a mono can go closer to the wind than your average cat; this means a shorter distance from point A to point B if traveling directly towards the wind.

But, and its a big but (one T) catamarans on average are faster, that means even though they might have to travel a longer distance, they will usually show up at the destination faster than its mono counterpart.

Especially if we are talking longer distances, let’s say around the world or Atlantic crossings, then there is no discussion over which is the fastest.

Check this list of catamaran speeds to learn more .

No more merry-go-round while at anchor

One of the things I hated the most when living and sailing on a monohull was getting seasick when not even sailing. The wind pushing you one way and the waves the other makes for an incredibly potent mix of sea-sickness.

On a cat, that’s not really an issue; yes, it will swing around a little, it might even swing a little extra since it catches a lot of wind, but it is not going to roll! Which is a huge deal!

How to become a better sailor

Everybody says that to become a good sailor, you must get out there earn your experience, but without the correct feedback and conclusions, you might be at risk of sub optimizing your skillset.

This means that unless you bring someone very experienced, you might create habits that only work under the circumstances you have practiced, that is, calm weather close to shore.

What you need is someone to tell you, “that works today, but it will get you into trouble in X and Y situations,” those tips are vital! Get the opinion of someone you trust, whether it’s online or an actual person tagging along!

The American sailing association has a pretty cool book about handling large catamarans, check it out here.

Sailing single-handed

Catamarans, when set up correctly, can be sailed single-handed or shorthanded. Some of the changes you’ll have to make include;

• Get an autopilot
• Make sure your lines go all the way to the cockpit, so you don’t have to leave your GPS, radar, etc.
• Remove things that are obstructing your view; there are only two eyes on board!
• Ensure you have enough physical power to handle the winches, sail, etc., if you don’t? Hit the gym; if that doesn’t work, buy electric winches.
• Practice sailing single-handed(but have a passive crew tag along for safety) and figure out what else you need.

More info on how to sail single-handed

Anchoring your cat at sea

One way to do this is to use a sea anchor, basically a parachute in the water that breaks your movements.  more on sea anchors here

The sea depth in the middle of an ocean can be thousands of meters, so bringing that much anchor chain doesn’t really work. What you would do is drift under control, that is, situating the boat in a comfortable position, and that doesn’t make you drift too much in the wrong direction.

Picking up a mooring ball

This is a common question, but I’m not sure why it intimidates people as much as it does. It is probably the easiest way to anchor of them all.

Basically, what you want to do is;

• Prepare your bridle
• Head into the wind slowly, approach the ball on the same side of the centerline as your friend, who will later pick it up.
• Take into consideration the drift occurring by the wind and current.
• Use a boathook, stick, or whatever to pick up the line from the mooring ball and attach it to the center of your bridle.
• Put the boat in reverse, give it a little throttle, and tension the lines so that you can trust your anchoring
• Voila, you’ve picked up your first mooring ball!
• How to make your useless friend useful onboard

Turn that useless friend into and a vital asset!

The best way to prepare for troublesome situations is to think through what problems may happen and what you want to do when it happens. What you do is you bring that diamond in the rough that is your friend onboard, you discuss a few situations, you tell her what you want her to do and when.

Then you practice, not full-on, but you will show your friend how things are done; let’s say you want help with anchoring. Do a walkthrough of the process where you let your, now a little bit shinier diamond, handle the ropes and respond to commands. Offer honest and concrete feedback and let them succeed in the task.

Once you feel comfortable with your friend’s actions, you have accomplished two things, you have taught your friend a new skill, and you have acquired a crewmember! Glorious!

Bring your real best friend, the dog (or cat, for you weirdos 😉 )

Heeling is not only tough on us humans! On a cat (the boat), a cat(the animal) can move around more safely, and there is a smaller chance of it falling off. Many chose to keep the pet inside the boat, but I really do believe that your pets should also be able to enjoy the beautiful sailing and weather!

Prepare to see nothing.

I don’t mean beautiful islands and tropical beaches; you’ll see plenty of that! I mean, seeing where you are going, a cat has a lot of stuff in front of you(such as that glorious interior space), so if you’re used to your good old monohull, you might find it difficult at first to get at a good view of where you’re going. Especially when docking or in a marina.

Catamaran Sailing Techniques: Everything you need to know – Yachting World

The wind will give you a hard time.

A catamaran is basically a big box with floating sleds; boxes are not famous for aerodynamics. This box-shaped floater will catch a lot of wind and will make slow speed movements, such as docking, a little bit trickier.

To the rescue comes double engines with separate controls making it possible to do 360 turns on the spot and super small unballasted keels called centerboards.

Spring of the dock will be your new way of life.

Higher on the list, we looked at the box-shaped floating thing that is a catamaran and how much the wind affects it. This is also true when exiting a dock; all that force will make it impossible to head out if the wind blows towards the dock.

Spring off the dock to the rescue! This method uses simple physics of leverage to make your stern move away from the dock even though the wind and waves are pushing you back in.

Sign up to my  mailing list  for information on when that article is published!

Stop turning the wheel and start using your throttles.

The downside of a shallow draft is that it won’t have much that stops you from moving sideways with the wind; the upside of having a catamaran is that you have two engines!

When moving at slow speeds, let’s say docking, you dont have much “grip” on the water and not much water passing around the rudders. This makes handling a catamaran in the same way as a monohull very difficult.

Instead, the preferred method is to put the rudder at center position and turn by offsetting the throttle; higher throttle on your right engine will make you go left and vice versa. This allows for 360 spins and precis handling in tight spaces! Pretty neat, I would say.

Get used to that hellish banging noise!

Bridge deck clearance is a real thing on a catamaran, and if you’re on a smaller sized or just poorly built, you’ll get more banging than your teenaged self ever wished for(pun intended)!

So bridge deck clearance is the distance between the water and the lowest part of the boat between the hulls.

This is the part where the water will pass between the hulls, and under some circumstances, let’s say big enough waves, water will crash and hit the underside—making not only a lot of noise but also vibrations throughout the boat.

Bring all that crap that you thought you would have to leave on land.

“sailing is living the simple life and bringing only what you need,” someone said to me once; screw that! 🙂 On a cat, there is so much space that you’ll be able to bring almost anything that you want and need.

People bring everything from scuba gear(including a system to fill up the oxygen tanks) to washing machines!

Even though I consider myself to be a simple man when it comes to stuff (i live in a van, as some of you know 😉 ) I can totally understand the beauty of bringing a lot of creature comfort on board.

Shallow draft, yes, but how deep is the water, visual checks.

Before sailing the Bahamas, I would hear of stories almost every day of boats that went aground and either got stuck or wrecked their ships. I was terrified but once underway and a couple of months in, I couldn’t really understand how it could happen.

So I started looking into the information about different accidents that I could find, and something struck me, common sense isn’t that common…

I realized that many sailors trusted their GPS or maps more than they trust their own eyes. I could easily understand that the people who went aground were the ones that did not do visual checks when entering or moving through a shallow section.

When storms roll in, the seafloor, especially if made of sand, shifts, and depths, is rarely accurate on a map, and if your sailing with only a few feet to spare, you better keep an eye out!

If monohulls give you feedback like your mom at family dinner, then a catamaran is your dead budgie.

Maybe that title is a bit of a stretch and only applies to my family; if so, sorry about that, let’s carry on!

So when the wind hits the sails on a monohull, it leans to the side, everybody gets seasick, and you want to go home, that is not all bad! That same feeling also gives the captain a sensation of how much force is acted upon the sails, something vital if you want to stay afloat.

The issue with a catamaran is that it does not offer feedback to the helm in the same manner; there is nothing dangerous about it; it is just different. The problem occurs when you expect feedback in the shape of leaning before you start reefing.

If you wait for that, you’ll soon find yourself in trouble!  The easiest and safest way is to use a “wind speed rule of thumb,” basically a standard operating procedure for  putting the reefs in based on apparent wind. Once the wind speed hits X m/s, you put your first reef in; when the speed hits Y m/s, you put the next reef in, and so on.

See a squall coming? Reef early!

A gust of wind? Head down, not up!

I know, I know, I compare monohulls and cats all the time… and yes, here’s one more comparison!

Some of you single-hull-people out there might be tempted to head upwind if there’s a gust hitting the sails, I would rethink that strategy and recommend you train your reactions to do the opposite! 

Heading upwind(on a cat) during a gust will increase the risk of capsizing (flipping over is extremely rare, but if you’re ever going to pull it off, here’s your chance!).

Gybe like Barry White would

I’m not sure we see the same things here, but what I’m trying to say is that you want to take it nice and smooth on the transition from one side to the other.

Tighten in the sheet, pull the mainsail to the center and slowly pass from one side to the other; this will decrease the wear and tear and reduce the risk of injuries from the beam swinging like a

Wow, that was fast! Why trimarans are SO much fun to sail – and how to do it

• Theo Stocker
• February 13, 2024

For their size, trimarans can punch well above their weight in speed, cruising potential and fun. Monohull sailor Theo Stocker gets to grips with how to handle one

Humans tend to gravitate into tribes of like-minded enthusiasts, enjoying the encouragement, support and sense of identity, while often looking askance at others; sailors at motorboaters, cruising sailors at racers, monohull sailors at raft, I mean, multihull sailors, and everyone looks askance at jet-skiers.

Large cruising catamarans (40ft now counts as a small one) are a world apart from monohull sailing, but there’s a sub-tribe of sailors dedicated to life on three hulls and builders such as Dragonfly, Corsair, Farrier, and Astus give them plenty of choice.

I’ve been sailing a 22ft (7m) Astus 22.5 this season, with just enough space for a family of four and a minimum of creature comforts. Thanks to her VPLP-designed hulls and 650kg all-up weight, we can sail upwind at 7-plus knots and downwind at over 10 knots with ease, all on a roughly even keel, while the kids play Duplo down below. It can also be beached and is towable behind a car.

Having, it seems, caught the trimaran bug, I wanted to get better at sailing and handling the boat, but my monohull sailing experience and habits were proving something of a hindrance, so we sought advice from some existing trimaran owners, and well as the UK’s top multihull sailors.

Much of the advice will apply to all multihulls , whether two or three-hulled, while other parts are just for small trimarans. I also found that brushing-up some of my rusty dinghy sailing skills helped get my head around what we were trying to do.

To try out our expert tips we went out sailing to see what difference they made. On the day, we got a solid Force 4-5 southwesterly, averaging 16 knots, but fluctuating between 12 and 20 knots true.

Blasting about on a sporty trimaran is a whole world of fun, but is much calmer than it looks

Trimaran sail trim

One of the biggest differences between a cruising monohull and a multihull is how the mainsail is trimmed. Leech tension on a yacht is often largely controlled by the kicker and the backstay, while the mainsheet sheets the mainsail in and out, predominantly controlling the angle of the boom to the centreline, and there may be a short traveller.

On a mulithull, however, there’s more than enough space for a good, wide traveller. Those who sail on performance monohulls will also be used to this. The sail shape is mainly controlled by the mainsheet, and the traveller then moves the boom towards or away from the centreline.

This is exaggerated on a multihull which has wide shrouds, swept well aft with no backstay, making space for a powerful square-top mainsail with full-length battens. There’s no backstay to bend the mast and flatten what is anyway a pretty rigid mainsail.

The mainsheet purchase creates enough power to control the leech of the square-top mainsail

Depowering a trimaran

Sailing on a monohull, heel and weatherhelm and eventually a broach give loads of warning that you’re pushing too hard. With straight hulls and little heel, those warning signs don’t really apply to multihulls.

In reality, however, there are a host of warning signals that it’s time to back-off; they’re just a bit different. Even then, there’s still a large safety margin before you get close to danger.

By way of reassurance, with the boat powered up on a beat, Hein, from Boats on Wheels, the boat’s owner, stood on the leeward hull and lent on the shrouds. Even as his feet got wet and the wind gusted at the top of Force 4, the boat didn’t bat an eyelid, thanks to the huge buoyancy of the floats.

Even with a person on the leeward float the boat was extremely stable

On the water – sail trim

My first inclination was to point the boat as high upwind as possible, pin the sails in and go for height. Doing that resulted in a not-terrible boat speed of 5-6 knots and a good pointing angle.

Free off by a handful of degrees however, and ease the sails just a smidge, and the speed leapt up to 8-9 knots – over 50% more; a huge increase. So, don’t pinch. If you had a decent chartplotter on board, you could find your optimum speed to angle using velocity made good (VMG).

I was also tempted to pinch in the gusts, but it’s better to hold your course and let the speed increase until the main needs easing.

On the wind, it’s time to get the boat fully powered up

If that’s the case, drop the main down the traveller an inch or two or ease some twist into the mainsail and it makes all the difference in the world, but not so far that the top battens fall away and invert – that really isn’t fast. Push too hard and the boat will slow down, largely from the drag of submerging the leeward float and crossbeams. If you’re still overpowered and the main is luffing, it’s time to reef. Downwind is different, but we’ll get onto that later.

After we put a reef in the main, our boat speeds upwind remained largely the same, and the boat was much happier. I came away feeling reassured that even a little trimaran like this would be pretty difficult to capsize, and there were always plenty of warning signs telling me to take my foot off the pedal a little.

Catamaran sailing skills: Mooring and anchoring a multihull

How do you make an average passage speed of 7 knots, fit in three double cabins and a huge saloon…

Monohull or multihull: which is best for blue water?

As former editor of Yachting World, David Glenn has plenty of experience of both monohull and multihull cruising. Here he…

Tacking and gybing a trimaran

Everyone knows that multihulls don’t tack as well as monohulls. Straight hulls and wide beam don’t lend themselves to turning, especially when coupled with the displacement and fixed keels of big cats. Trimarans are a little easier, with a single central daggerboard to act as a pivot, and one or other of the floats will generally be clear of the water. On the downside, light displacement means that there isn’t much momentum to keep you going through the turn and plenty of windage to stop you.

On a trimaran the central daggerboard helps the boat to turn by providing a central pivot point that catamarans lack

Speed is your friend. Build speed up before the tack to give you as much momentum as possible. The helm needs to steer positively into and through the turn, and if necessary, keep the jib backed on the new windward side to help the bow through the wind. Don’t worry about scrubbing speed off, but you don’t want to get stuck in irons.

When it comes to gybing, speed is again key. The turning bit isn’t going to be an issue as you’ll be scooting along, but the faster you’re going, the less load there will be on the sails. The more you slow down, the more the true wind will pile up.

Trimaran sailing skills

Tacks took a bit of practice. It felt plain wrong to jab the tiller across the boat, slamming a big break on in the water but I ended up putting us through the tacks far too slowly, losing a lot of speed. A more aggressive approach worked better. On the Astus, the traveller was between me and the tiller, so the tiller extension needed to be swung around the stern behind the mainsheet onto the new side.

Similarly, old habits of controlling a gybe needed to be modified. With the asymmetric set, we were planing at well over 10 knots, and the ideal is to stay on the plane. Heading dead downwind and centring the main lead to a more violent manoeuvre than flying into the gybe as fast as possible and, as the boom was never that far out thanks to the apparent wind angle, it didn’t need much extra controlling.

Coming up onto the wind after the gybe helped the asymmetric around the front of the jib and to fill on the new side. Stay too deep and it’ll get blanketed by the main. Once we had built up some apparent wind, we could bear away again.

You’ll be on a course deep downwind before you know it, hitting speeds in the double digits

Downwind in a trimaran

Upwind cruising may be fun in a multihull, but bearing away and going with the wind is what it’s all about. Easily-driven hulls, a generous sailplan and light weight mean you can be up and planing, leaving displacement boats wallowing in your wake.

The big difference comes from apparent wind. If you’re in a boat that can do 15 knots downwind in 20 knots of true wind, the resulting wind angles can really mess with your head.

To get going then, says Brian Thompson, ‘Use those leech tell-tales again when sailing downwind and reaching to set the correct twist through the mainsheet, and use the traveller to set the correct angle of the whole sail to the wind.’

As the wind and your speed builds, bear away and trim the main accordingly.

In theory, you shouldn’t need to ease the traveller at all, but you may need to if you want to sail deep downwind. As the gust fades, you’ll find the boat slows down, so you can come back up towards the wind a little to pick up some more breeze, and then bear away as you accelerate again.

Bear away as the boat accelerates. Your course will be something of a slalom as you look to keep a consistent wind angle

This results in something of a ‘slalom’ course, and will also be accentuated if you’re sailing down waves, but that’s all quite normal for apparent wind sailing. Ultimately, you’re looking for a consistent apparent wind angle, even if the resulting wake isn’t straight.

It’s worth remembering that apparent wind reduces the felt effect of the wind, so you need a sailplan to suit the true, not apparent wind speed.

I found that the boat was more sensitive to having a balanced sailplan and trim downwind than upwind, largely because you’ve got almost double the canvas up, with the bowsprit as an extra lever. When weather helm built, I needed to ease the mainsheet to increase twist to depower so that I could bear away. I must admit, getting the boat balanced, sailing fast and light on the helm at 15 knots was something I came away feeling I needed more practice at.

Reviewing the images, I suspect the asymmetric was sheeted in too hard, with too much twist in the main.

Getting a float fully submerged is when it’s time to back off

On the water

Unfurling the gennaker worked best on a beam reach, giving plenty of airflow over the sail to help it fully unfurl. This was also roughly the fastest point of sail, ideal for getting up some speed for apparent wind sailing. We mostly had the sails set for a close reach, even when we were beyond 120º off the true wind on a broad reach.

It was possible to soak deeper downwind, but lose the apparent wind benefit downwind and our speed dropped off dramatically, prompting us to point a bit higher to find some more speed.

As the boat powered up, it paid to hold a slightly higher angle than I would have done in a monohull for the boat to properly take off and get up into double digit speeds – topping out at 15 knots. Lymington to Cowes would have taken us just half an hour at that speed. It’s easy to give yourself a heck of a beat back!

We were sailing on a pretty flat day, so didn’t have to contend with any waves to speak of. On the recent RTI this is what caused the capsizes of at least two multis, a sobering reminder that you need to sail much more conservatively in lumpier conditions.

The bows want to point downwind, so a stern-first approach works with rather than against the boat

Coming alongside

A 650kg boat with no draught and plenty of windage feels dreadfully skittish when manoeuvring in confined spaces. Straight hulls with no forgiving curves and fragile-looking sharp bows make berthing tricky. You’ve got a couple of advantages on your side, however. In the Astus, the floats are at pontoon height making stepping off easy.

Whether you have an engine in each hull of a cat, or one in the central hull of a tri, there’s also a lot more leverage to play with to turn the boat and drive her on or off the pontoon. A steerable outboard gives you even more options.

If the boat has a lifting keel or daggerboards, put them down if there’s enough depth to give you a pivot and to resist drifting. Think about getting corners onto the pontoon, rather than putting the boat alongside. On tris, you won’t be able to get to the bow to fend off as it’s too narrow. You can rig a fender up forwards on a line, and two fenders are enough on the flat sides.

Steering with the outboard towards the pontoon will drive the stern in more; steer away to drive the bow in more

Offshore wind

Coming onto the pontoon with wind blowing off, it worked well coming in stern first. If there’s a tide running, you’ll want to be heading into the tide, so find a spot down wind and down tide to start your approach so you come in at an angle.

On our first attempt we had a bit of tide under us to start with so we came in at a much steeper angle, almost 90º, although this worked out OK in the end.

The crew could then step ashore, taking a line from the stern quarter round a cleat.

Drive forwards against the line and the bow will obediently drive up towards the pontoon, bringing you flat alongside. Getting off was simple, releasing the bowline, and allowing the bow to swing out the before slipping the stern line.

Coming in astern and stopping upwind of the berth meant the bows blew towards the pontoon far to quickly

Onshore wind

Getting onto and off a pontoon with onshore wind proved rather trickier. On our first attempt we came in stern first. The issue was that once we were just upwind of our desired berth and stopped, we lost steerage and the bow immediately blew off with alarming speed towards the pontoon.

Going ahead would only increase the force of the impact, while going astern only increased the bow’s sideways drift. I managed to back out without smashing the bow, but only just, and ended up awkwardly stern to the wind with the bows pointing at the pontoon.

On our second attempt we came in bows first but having aimed at the berth, I had to motor the stern to leeward to stop the bow hitting, making for a rather forceful coming alongside.

On take three, I came in forwards and began ferry gliding towards the berth early, keeping the bows to windward of the stern. Being able to steer with the outboard meant I could go ahead to keep the bow up, and go astern with the engine pulling the stern down toward the pontoon. In this way, it was possible to come in pretty well controlled and parallel to the berth.

To get out, motoring astern against a bow line pulled the entire boat clear before slipping the line

Leaving was a different proposition all together, as I didn’t want to drag the bow along the pontoon, or to drive hard onto it to spring off. Instead, we rigged a slip-line from the forward cross beam. Going astern against this, and then turning the engine towards the wind, I could pull the stern, and the rest of the boat, out and away from the pontoon.

Keeping power on astern, once we’d reached a decent angle, we slipped the line and went astern, finding steerage way almost at once, with the bow following obediently in our wake with more control than I had anticipated.

Whether the wind is blowing onto, or off the pontoon, you want the engine to be driving or pulling the boat off the pontoon with a line on the corner you are going away from. That way you avoid point-loading fine ends where it’s hard to fender.

You’ll want a bridle to reduce swinging, but keep the pick up lines on the bow as backup

Anchoring and mooring a trimaran

While mooring a catamaran is complicated by the lack of a central bow, things should be simpler on a trimaran, and they are, mostly. Picking up a mooring buoy from the main hull bow with a low freeboard and dropping the pick-up line onto a cleat is easier even than a monohull.

The bow may be narrow, but for any lines that pass through a ring on the buoy, you still need to take it back to the same cleat to avoid chafe. That should be it, but windage from the two extra bows and the lack of keel mean the boat can dance merrily around the mooring buoy in a breeze.

Rig the bridle so the buoy sits to one side to stabilise the boat

In practice, we found that a trimaran benefits from a mooring bridle in the same way that a catamaran does. It can’t be rigged from the floats’ bows, as there are no mooring cleats, so a line passed around the outboard ends of the forward beams gave a pretty good angle, again with long lines passed through the mooring and back to the same side. The main pick-up lines stay as a safety backup.

The other trick is to rig the bridle asymmetrically so that the buoy sits to one side or the other, just enough to not be dead head to wind, making it much more stable in the wind.

On the plus side, the lack of draught or keel means that you’ll nearly always be lying head to wind, so the cockpit remains nice and sheltered whatever the tide’s doing.

We ran out of time on the day to try anchoring, but rigging a bridle, effectively a long snubber to a point on the anchor chain in a similar way wouldn’t be tricky.

If you needed not to swing, or to behave more like deeper boats nearby, hanging a bucket over the stern can help, or there’s always anchoring with a kedge, either out ahead in a V, or in line astern.

The Ultimate Guide to Choosing Between a Sailboat or Catamaran for Your Sailing Adventures

C hoosing between a sailboat and a catamaran for your sailing adventures is a significant decision that depends on various factors, including your sailing preferences, experience level, budget, and intended use. Here's an ultimate guide to help you make an informed decision:

1. Sailing Experience:

• Sailboats: Typically require more skill and experience to handle, especially in adverse weather conditions. Ideal for sailors who enjoy the traditional feel of sailing and are willing to invest time in learning and mastering the art.
• Catamarans: Easier to handle, making them suitable for beginners. The dual-hull design provides stability, reducing the learning curve for those new to sailing.

2. Space and Comfort:

• Sailboats: Generally have a narrower beam and less living space. However, some sailboats may offer comfortable cabins and amenities.
• Catamarans: Wider beam creates more living space. Catamarans often have multiple cabins, spacious saloons, and expansive deck areas, providing a more comfortable living experience.

3. Stability:

• Sailboats: Monohulls can heel (lean) while sailing, which some sailors enjoy for the thrill but can be discomforting for others.
• Catamarans: Greater stability due to the dual hulls, providing a more level sailing experience. Reduced heeling makes catamarans suitable for those prone to seasickness.

4. Performance:

• Sailboats: Known for their upwind performance and ability to sail close to the wind. Some sailors appreciate the challenge of optimizing sail trim for efficiency.
• Catamarans: Faster on a reach and downwind due to their wide beam. However, they may not point as high into the wind as monohulls.
• Sailboats: Typically have a deeper draft, limiting access to shallow anchorages and requiring deeper marina berths.
• Catamarans: Shallow draft allows access to shallower waters and secluded anchorages, providing more flexibility in cruising destinations.
• Sailboats: Generally more affordable upfront, with a wide range of options available to fit different budgets.
• Catamarans: Often more expensive upfront due to their size and design. However, maintenance costs may be comparable or even lower in some cases.

7. Mooring and Docking:

• Sailboats: Easier to find slips and moorings in marinas designed for monohulls.
• Catamarans: Require wider slips and may have limited availability in certain marinas, especially in crowded anchorages.

8. Intended Use:

• Sailboats: Ideal for traditional sailors who enjoy the art of sailing, racing enthusiasts, or those on a tighter budget.
• Catamarans: Suited for those prioritizing comfort, stability, and spacious living areas, especially for long-term cruising and chartering.

9. Resale Value:

• Sailboats: Generally have a more established resale market, with a wider range of buyers.
• Catamarans: Growing in popularity, and well-maintained catamarans often retain their value.

10. Personal Preference:

• Consider your personal preferences, the type of sailing you plan to do, and the kind of lifestyle you want aboard your vessel.

In conclusion, both sailboats and catamarans have their advantages and disadvantages. Your decision should be based on your individual preferences, experience level, budget, and intended use. If possible, charter both types of vessels to experience firsthand how they handle and to help make a more informed decision based on your own preferences and needs.
