• Navigating with Ease: The Comprehensive Guide to Bow Thrusters

What is a Bow Thruster?

Bow thrusters have become increasingly popular among boat owners, but what exactly are they? In layman's terms, a bow thruster is a propulsion device installed in the bow, or front, of a boat to aid in maneuvering. The device uses a motor to power a propeller, pushing water perpendicularly to the boat's heading and providing a lateral, or sideways, motion. Think of it as power steering but for your boat, allowing you to move sideways without changing the direction your boat is facing.

Why Should You Care?

Do you find docking stressful? Are you anxious about navigating through tight marinas? Bow thrusters can relieve this stress by offering precise control over your boat's movement. Whether you are a seasoned sailor or new to boating, a bow thruster can significantly enhance your maneuvering capabilities, making your boating experience more enjoyable and less stressful.

Historical Background

While bow thrusters may seem like a modern convenience, the idea isn't new. Early versions of lateral propulsion devices date back to the early 20th century, although they were primarily used on larger commercial vessels. It wasn't until advancements in technology made these devices more compact and affordable that they became popular among recreational boaters.

Types of Bow Thrusters

Hydraulic bow thrusters.

Hydraulic bow thrusters operate using a system of hydraulic pumps and motors, typically running off the boat's main engine. These thrusters are often more powerful and can be more efficient, especially for larger vessels. One key advantage is their ability to run for longer periods without overheating, making them ideal for boats that require extensive maneuvering.

Electric Bow Thrusters

Electric bow thrusters are the go-to for smaller boats. These thrusters run off your boat's electrical system and are generally easier to install. They are also less expensive upfront but may not have the same power output or efficiency as hydraulic systems.

Sidepower Bow Thruster: A Special Mention

When it comes to trusted brands, Sidepower stands out. Known for their high-quality, efficient, and reliable bow thrusters, Sidepower has become a household name for many boaters. If you're looking for a bow thruster that combines both performance and durability, Sidepower is worth the investment.

Tunnel vs. Retractable Thrusters

Tunnel thrusters are the most common type and involve a tunnel-like tube fitted through the hull, housing the propeller. Retractable thrusters, on the other hand, can be retracted into the hull when not in use, reducing drag.

Bow Thruster Kits

What's in the kit.

When purchasing a bow thruster, you often have the option to buy it as a complete kit. These kits generally include the thruster unit, tunnel, propellers, and control panels—basically, everything you need for a successful installation. The convenience of having all these components together can't be overstated. It's like getting an all-in-one care package for your bow thruster needs.

Do You Need One?

The real question is, do you need a complete kit? If you're new to bow thrusters or are unsure of the individual components needed, then a kit can be invaluable. Not only does it take out the guesswork, but it often comes with a set of installation instructions that can make your life significantly easier.

Buying Separate Components

If you're an experienced boater or have specific needs that can't be met by a standard kit, purchasing individual components might be the way to go. This allows you to customize your setup for optimal performance, though it does require a good understanding of how the different components work together.

Importance of Side Power in Bow Thrusters

Maneuverability.

The term "side power" refers to the lateral thrust produced by the bow thruster. The higher the side power, the better your boat will respond to steering inputs. This is crucial when you're navigating through tight spaces or docking in difficult conditions.

High side power also contributes to safety. If you're caught in choppy waters, a strong bow thruster can help you maintain control and avoid obstacles, minimizing the risk of collision or grounding.

The Installation Process

Professional installation.

Given the complexity of installing a bow thruster, many boat owners opt for professional installation. This involves hull modification, electrical or hydraulic work, and fine-tuning, tasks best left to the experts unless you have significant experience.

DIY Installation

If you're a seasoned DIYer with a strong understanding of boat mechanics, installing a bow thruster yourself can be rewarding—though challenging. You'll need specialized tools and materials, not to mention a fair amount of time.

Tips and Tricks

Regardless of whether you go the DIY route or opt for professional installation, some tips can make the process smoother. One such tip is to dry-dock your boat for easier access to the hull. Also, make sure to consult the manual thoroughly before starting.

Bow Thrusters for Sale: What to Look For

Brand reputation can tell you a lot about the quality of a bow thruster. Established brands like Sidepower are generally a safe bet, offering a combination of reliability, efficiency, and customer service.

Bow thrusters can be a significant investment, with prices ranging from a few hundred to several thousand dollars. While it's tempting to go for cheaper options, remember that this is a long-term investment. Quality should be a leading consideration.

Power and Efficiency

Before buying, assess your boat's size and the level of maneuverability you desire. This will help you choose a bow thruster with the appropriate power and efficiency.

Reviews and Ratings

Online reviews and ratings can provide valuable insights into the performance and reliability of a bow thruster. Take the time to read through customer feedback before making a decision.

Installing Bow Thrusters

Step-by-step guide.

If you've opted for DIY installation, you'll want a thorough step-by-step guide to navigate you through the process. This usually comes with the bow thruster kit or can be downloaded from the manufacturer's website. Remember, missing even one small step could result in poor performance or, worse, damage to your boat.

Time and Effort

Installing a bow thruster isn't a quick job. Depending on your skill level and the complexity of your boat, it could take anywhere from a few hours to a full day or even longer. Plan accordingly and don't rush through the installation.

Precautions

Safety first! Always ensure that your boat is securely dry-docked and that you're following all safety guidelines when working with electrical or hydraulic systems. A little caution can save a lot of trouble later.

Boat Thrusters

H3: how they differ from bow thrusters.

Boat thrusters and bow thrusters are not exactly the same. While bow thrusters are specifically located at the bow, boat thrusters can be placed elsewhere, including the stern. The purpose remains the same—to assist with maneuvering—but the placement can affect the boat's handling characteristics.

Stern Thrusters: The Counterpart

Stern thrusters serve a similar function as bow thrusters but are installed at the rear end of the boat. Some boaters prefer having both types for maximum control over their vessel, particularly in challenging navigational situations.

Narrowboat Bow Thrusters

Are they different.

Narrowboats pose a unique set of challenges due to their length and narrow width. Standard bow thrusters may not provide the level of control required for these vessels. Specialized narrowboat bow thrusters are designed to tackle these unique challenges.

Unique Challenges

The unique challenges of navigating a narrowboat—like tight turns and limited space for maneuvering—require a specialized bow thruster. The focus here is more on precision than power.

Fortunately, several brands offer bow thrusters specifically designed for narrowboats. These units typically provide finer control and may come with features like remote operation for ease of use.

Bow Thrusters for Small Boats

Is size a limiting factor.

You might think that smaller boats wouldn't benefit from a bow thruster, but that's not the case. Compact bow thrusters are available for smaller vessels, and they offer many of the same benefits as their larger counterparts.

Compact Models

Several brands offer compact bow thrusters suitable for small boats. These are generally easier to install and less expensive, making them a viable option for casual boaters or those on a budget.

Thrust-to-Weight Ratio

When choosing a bow thruster for a small boat, it's crucial to consider the thrust-to-weight ratio. A thruster that's too powerful could be overkill and a waste of resources, while an underpowered one might not provide the maneuverability you need.

Thrusters in Ships

Scale and complexity.

Ships, being much larger than typical recreational boats, require thrusters that can produce a tremendous amount of power. These are often complex systems that involve state-of-the-art technology to ensure maximum efficiency and safety.

Types of Ship Thrusters

Ships generally utilize specialized types of thrusters, like azimuth thrusters and tunnel thrusters, to provide both maneuverability and stability. These are far more advanced and are custom-engineered to fit the specific needs of each ship.

Safety Measures

Given the scale and potential risks, the installation and operation of thrusters in ships are governed by stringent regulations. Adherence to these guidelines is critical to ensure the safety of both the vessel and its occupants.

Boat Thrusters Market

Emerging trends.

The boat thruster market is continuously evolving, with new technologies and designs making their way into the mainstream. Features like wireless control and automated navigation systems are gaining popularity, offering boaters unprecedented levels of control and convenience.

Where to Buy

From marine supply stores to specialized online retailers, there are numerous avenues to explore when shopping for a bow thruster. Many boaters also opt to buy directly from manufacturers to ensure they're getting the latest models.

Used Bow Thrusters

Buying a used bow thruster can be a cost-effective alternative, but it comes with its own set of risks. Always ensure that you're buying from a reputable source and that the thruster has been thoroughly inspected and tested.

Whether you're a casual boater looking for a bit more control over your vessel or a professional mariner in search of advanced systems, bow thrusters offer solutions for a variety of needs. From small boats to massive ships, these invaluable devices make navigation easier, safer, and more efficient. With numerous options available in the market—from compact models to specialized kits—there's likely a bow thruster that's perfect for you.

The Essential Guide to Bow Thruster Construction and Functionality

Bow thrusters are a type of propeller-shaped system fitted on the bow (forward part) and stern (known as stern thruster) of the ship. They are smaller in size than the ship’s propeller and help the vessel be more manoeuvrable at lower speeds.

Bow thrusters are generally used to manoeuvre the ship near coastal waters and channels or when entering or leaving a port during bad currents or adverse winds.

Bow thrusters help tugboats berth the ship to avoid unnecessary time and, eventually, money wastage because the vessel stayed less in the ports. The presence of bow thrusters on a vessel eradicates the need for two tugs while leaving and entering the port, thus saving more money.

Nowadays, ships have both bow and stern thrusters, which makes them independent of tugboats for manoeuvring in the port limits (if the port regulation does not make it compulsory to use tugboats).

Installation Of Bow Thruster

Generally, side thrusters are transverse thrusters placed in a duct at the ship’s forward and aft end. The thruster set at the forward end is known as the bow thruster, and the one placed at the aft end is known as the stern thruster.

The requirement for the number of thrusters to be installed depends on the ship’s length and cargo capacity. The vessel’s route also plays an important factor as many countries have local regulations that stipulate the compulsory use of tugboats to enter or leave their port limits.

For the installation of the side thrusters, the following things are essential:

• The thruster compartment, also known as the bow thruster room, should be easily accessible from the open deck by the ship’s crew
• Most seagoing vessels use an electric motor for the thruster, which is heat-generating machinery and must, therefore, be positioned in a dry and well-ventilated area.
• The bow thruster room should have a high-level bilge alarm , and the indication should be provided in the engine control room and bridge.
• The thruster room should be well-lit
• The room should have at least one light from the emergency source.
• In the case of installation of more than one panel, make sure to operate the thruster from only one panel at a time.
• The thruster room should not be used to store flammable products in the area of the electric motor.
• The tunnel or conduit containing the propeller must be installed perpendicular to the ship’s axis in all directions.
• The propeller should not protrude out of the conduit
• Grid bars may or may not be fitted at both ends of the tunnel (taking into account how much debris the ship bottom will experience in its voyage). The number of bars for to be kept at a minimum as they tend to reduce the thrust force and overall performance of the bow thruster (or stern thruster)
• Sharp edges on the grid bars are to be avoided. A trapezoidal shape with no sharpness is a good choice of design for grid bars installed perpendicularly to the direction of the bow wave
• The design and position of the thruster tunnel should not interfere with the water flow under the hull or should not add to hull resistance
• Ensure that the material used for the installed thruster does not foul existing equipment inside the ship, such as steering links.

Construction and Working of Bow Thrusters

The bow and stern thrusters are placed in the through-and-through tunnels on both sides of the ship. There are two such tunnels at the forward and aft ends of the ship.

The thruster takes suction from one side and throws it out at the other side of the vessel, thus moving the ship in the opposite direction. This can be operated in both directions, i.e. port to starboard and starboard to port.

The bow thrusters are placed below the ship’s waterline. For this reason, the bow thruster room should be checked for water accumulation at regular intervals.

The bow and stern thrusters can be electrically, hydraulically, or diesel-driven. However, the most commonly used are electric-driven thrusters, as in hydraulic-driven thrusters, there are many leakage problems.

Also, diesel-driven bow thrusters require more maintenance, and someone needs to go to the thruster room every time before starting to check the thrusters.

The thrusters used are usually of the CPP type, i.e., the blades on the propeller boss can be moved to change the direction of the thrust.

The boss, which carries the blades, is internally provided with a movable shaft (operated by hydraulic oil), also known as a Hydraulic Pod Motor-driven Thruster.

Once the signal to change the pitch is given, hydraulic oil will be supplied to operate the internal shaft (within the boss) to change the blade angle of the thruster (as shown in the video).

Related Read:  10 Precautions to Take Before Operating Controllable Pitch Propeller (CPP) on Ships

The motor shaft drives the thruster shaft via a pinion gear arrangement. The sealing gasket is provided in the motor casing which holds the water which is in the tunnel.

The Thruster assembly consists of the following components:

• The electric motor with safety relays
• The flexible coupling between the motor and thruster
• Mounting and casing for the electric motor
• The connecting flange and shaft
• Motor casing seal
• The tailpiece with shaft seal
• The propeller shaft
• The zinc anodes
• Grid with bars at both ends of the tunnel

Operation Of Bow Thruster

A bow thruster consists of an electric motor mounted directly over the thruster using a worm gear arrangement. The motor runs at a constant speed, and whenever a change is required in the thrust or direction, the controllable pitch blades are adjusted.

These blades are moved, and the pitch is changed with the help of hydraulic oil, which moves the hub on which the blades are mounted. As the thruster is of controllable pitch type, it can be run continuously, and when no thrust is required, the pitch can be made to zero.

The bridge controls the thruster, and the directions are given remotely. In remote failure, a manual method for changing the pitch is provided in the thruster room and can be operated from there.

Related Read:  How Bow Thruster is Used for Maneuvering a Ship?

Usually, the hydraulic valve block, which controls the pitch of the blades, is operated in the BT room to change the blade angle in an emergency.

When the Bow Thruster is operated alone and the signal is given to operate the pitch at the port side, the thrust will turn the ship towards the starboard side from the forward part.

Similarly, when the Bow Thruster is operated alone, and the signal is given to run the pitch at starboard side, the thrust will result in turning the ship towards the port side from the forward part.

When the stern and bow thruster are operated together on the same side, the ship will move laterally towards the opposite side.

As seen in the above diagrams, the bow thruster and the stern thruster provide excellent manoeuvrability to the ship.

Things To Note While Operating Side Thrusters

• Ensure that the motor is started well ahead of the thruster operation and that the hydraulic lines are opened.
• Never operate the thruster beyond its rated load, else it may lead to tripping of the motor.
• Gradually increase the capacity and shift the pitch. Avoid sudden changes in the BT movement.
• The side thrusters are considered as an “on load” starting device, i.e. they should only be operated when they are submerged in water.
• Before operating the thruster, check for small craft, swimmers, boats and tugs adjacent to the thruster tunnel.
• Never touch any moving parts or the electric motor in operation
• In the case of installation of more than one panel, ensure the thruster is operated from only one panel at a time

Maintenance Of Bow Thrusters

1) The insulation must be checked regularly and kept dry. This is done because bow thrusters are not used frequently and thus there are chances of damages by moisture. Moreover, because of the frequent idle state of the bow thrusters, there can be a reduction in insulation resistance, especially in colder regions.

2) The space heater is checked for working condition so that the insulation can be kept dry.

3) The bearings of the motor and the links are to be greased every month.

4) The condition of hydraulic oil is to be checked every month for water in oil and samples should be sent for lab analysis for further checking.

5) The thickness of the contactors is to be checked from time to time.

6) Checks are to be made for any water leakages in the bow thruster room which is an indication of seal leaking.

7) The flexible coupling between the motor and thruster should also be checked.

8) Check and inspect all the cable connections for cleanliness and tightness

9) Vacuum or blow clean the motor grid to remove the carbon grid, which may increase the operating temperature

Major Maintenance Of Bow Thrusters 

The major overhauling and maintenance of the bow and stern thrusters are done during the dry dock when the ship’s hull is out of the water, and the thruster blades and tunnel can be easily accessed.

Following maintenance is usually done in the dry docking:

• Replacement of the O’ rings and the sealing rings
• Removal of the pinion shaft
• Inspection and maintenance/ replacement of gear set
• Replacement of the bearings
• Repairs, cleaning and replacement of the blades
• Inspection of hub and repair if needed
• Inspection and overhauling of the oil distribution box (for operating propeller blades)

Advantages Of Using Bow Thrusters

1) Better manoeuvrability at low speeds of the ship.

2) Safety of the ship increases when berthing in bad weather.

3) Saves money due to the reduction of stay in port and less usage of tugboats.

Disadvantages Of Using Bow Thrusters

1) a huge induction motor is required, which takes a lot of current and load, and thus large generator capacity is required.

2) Initial investment is high

3) Maintenance and repairs are costly when there is damage.

The thrust force produced by the motor to move the ship will depend on various parameters, such as the hull design, power source, tunnel design, use of grids, draft and load of the vessel, etc.

The weather’s condition and the water’s state also play a vital role in BT performance.

Hi Mohit, I am a Marine and saftey advisor for a inland tanker company I have read your article about bowthrusters. Interesting. But I am looking for a graph or table or whatsoever on which you may indicate what the effect of the bowthruster is by increasing speed of the ship/barge.

In case the ship has no speed the turning point is about amidships. By increassing the speed the turning point shifts into the direction of the bow. Also the transverse force of the bowthruster (water force) will be in my opinion reduced by the by the water flowing longitudinally along the ship’s side. I thinkls at 3 knost speed the effect will be dramatically reduced. What is your opinion about that? .

VIDEO: How To – Use your bow thruster effectively

Our step-by-step guide shows you how to get the best from your bow thruster

Bow thrusters have become standard equipment on most craft over 30ft and even some smaller ones offer them as an option.

Almost any craft will benefit from having one and it’s certainly the one extra I would always tick on a new boat (and consider retrofitting to an older boat), especially if I were purchasing a single-engined craft or one with high windage.

We all know the basics of how to use a bow thruster, but overuse and/or poor usage often mean that skippers can cause themselves as many problems as they solve. I like to consider the bow thruster as an extra crew member who can lend a hand when needed but shouldn’t automatically be relied upon.

Electric bow thrusters have a finite period of time they can run before excess heat or power draw shuts them down. If you need to use it for that long, the chances are you are attempting the wrong manoeuvre. Some even come with a hold facility, but treat it with caution – it’s a hold for a few moments, not indefinitely.

Hydraulic ones are able to run for longer periods and can be used to hold the craft in position whilst lines are attached.

All bow thrusters are simple to use – just push the switch or lever in the direction you want the bow to go and it will follow – but there are a couple of things to watch. They really only work effectively when the boat has stopped or is moving at less than a knot – more than that and the water is moving past the thruster’s tunnel too quickly for it to be effective.

Though berthing using a joystick is deemed easy, there are still some key techniques to employ when using IPS

Video: How To – Berth single-handed

Leaving or arriving at at a berth is one of the biggest boating challenges. In this video we show you

The next thing to remember is that the thruster might well be moving the bow to port or starboard but the pivot point roughly in the centre of the craft means that the stern will be going in the opposite direction. So if your crew is trying to attach a stern line and you keep thrusting the bow towards the pontoon, you are almost certainly driving the stern out and making it harder for them.

I always advise using a short burst, then a slight pause, then a second burst and even a third if needed. These short bursts are often more effective than one long one and it prevents over driving the bow, which would mean you having to stop that momentum by driving it back in the other direction.

Pauses between bursts also allow the propeller and motor to stop so that if you need to change direction you aren’t putting excessive strain  on the system.

Be careful not to overdo the number of bursts, though – if the wind does take the bow many thrusters won’t be powerful enough to drive it back upwind. Far better to know when you’re fighting a losing battle and use the engines to move off safely and start the manoeuvre again.

A good exercise when berthing is to drive the bow slightly too close to the pontoon and use the thruster to push it away from the dock, helping to tuck in the stern and making it easier for the crew to attach a stern line.

Stern thrusters work in much the same way as bow thrusters, but as they tend to be fitted deeper below the water line, they are often quieter, which means that skippers tend to hold them on too long with exactly the same pivot issues as the bow thruster.

How To Use A Bow Thruster

Want better control and more confidence in your boathandling skills? A bow thruster may be just the ticket.

Bow thrusters often get a bum rap, particularly from boating purists who view them as somehow cheating when it comes to learning proper seamanship. While that view may be extreme, in the old guard's defense there's nothing more frustrating (or entertaining, depending on your vessel's location) than watching a boat bump into docks and nearby vessels due to wild manipulations of the bow thruster and a lack of basic boathandling skills. On the plus side, installation of a bow thruster can mean greater confidence at the helm, safer docking, and more time on the water. If you've been sitting on the fence, here's a look at the basics of bow thrusters to help you decide if installing one is right for you.

What They Are — Pros & Cons

A bow thruster is simply a propulsion device located at the bow that provides lateral (port and starboard) thrust, making the vessel more maneuverable. Bow thrusters often come as standard equipment on newer pleasure boats over 45 feet, but almost any midsize vessel can be retrofitted. The benefits of having a bow thruster are many, particularly for boaters who must routinely deal with gusty winds, strong currents, or crowded docking spaces. Maneuvering in tight areas is much easier, as a thruster allows the operator to turn the vessel to port or starboard without forward motion. This is particularly helpful with high-windage powerboats or sailing vessels with long, full keels.

Another benefit is the greater level of independence and confidence a thruster can offer, both to beginner and experienced boaters alike. Novice operators are more likely to actually get underway in more challenging conditions, while experienced captains can expand their options (sailing solo, for example) with greater safety. In both cases, installing a bow thruster is like recruiting a trusted crewmember, one that's always ready to lend a hand when pushing (or fending) off from a dock. A wireless control unit adds more convenience, allowing you to move around the boat while controlling the thruster. Imagine picking up that mooring ball with minimal effort (and shouting) or boarding without having to pull on a single dockline, bringing the boat to you with the push of a button.

As a final plus, you're also likely to enjoy a financial benefit when it's time to sell. Having a bow thruster will make your boat more attractive than similar boats on the market. This is particularly true for new or less experienced boat owners, who may not be comfortable handling larger boats in less-than-ideal conditions. And unlike other major upgrades such as engines or generators, most buyers don't care when a bow thruster was installed, as long as it works.

While the benefits of having a bow thruster installed are numerous, so, too, are the concerns with installing them. The first is cost. Although this will vary widely among the different makes, models, and styles (traditional tube units versus externally mounted ones, for example), you can expect purchase and installation of even the smallest, most economical unit to be around $5,000.

In lockstep with the above is the complexity of your particular installation. What's the best location? Will that water tank under the V-berth have to be shifted aft or relocated altogether? How powerful should it be? Will the extra weight in the bow affect performance? Will the installation void my hull warranty? All of these are valid concerns you'll want to research and review when considering any installation.

Finally, while thrusters are certainly helpful, they do not excuse you from mastering basic boathandling skills. You'll still need to know how to maneuver your boat in a wide range of conditions should your extra "crew member" ever go on strike.

Choosing A Bow Thruster

Installing a thruster can involve some major surgery, depending on the type selected and the design of your particular vessel. As such, you'll want to thoroughly research the various options available in order to select the one that's right for you.

Selecting a unit that's powerful enough to meet your performance requirements while matching the characteristics of your boat (type, size, hull shape) is crucial to getting the most benefit from your installation. Thruster performance is determined primarily by a vessel's windage and correct thruster location. Vessel weight is not typically a major factor in thruster selection for pleasure craft, unless they routinely operate in areas where the thruster will be constantly needed to counter strong currents or winds.

Some companies allow you to select a unit based on vessel characteristics such as length and displacement, but it's always a good idea to get a second opinion from a professional, particularly if dealing with unusual installation requirements. Once you decide to install a thruster, you'll need to make several choices including power source, mounting type, and number of propellers.

Electric Or Hydraulic?

From a power standpoint, bow thruster choices come down to two options, electric and hydraulic. Electric units can be further divided into 12- or 24-volt DC types, or even the occasional AC-powered unit, although DC power is a lot more popular and our focus here.

Hydraulic thrusters are a common choice for larger vessels, particularly those that already have hydraulic systems onboard to power the windlass or dinghy davits. Installing a hydraulic unit while utilizing an existing centralized hydraulic power source costs less and will greatly simplify the installation. Hydraulic thrusters are quieter than electric thrusters, have greater thrust, and can operate for extended periods of time without the worry of overheating or draining battery banks. They can also provide variable-speed control with proportional control and valves. Unless you already have hydraulic systems onboard, however, electric units will typically be a more economical choice.

An example of a thruster battery and charger installation.

Of the two electric options, 24-volt DC systems have some notable advantages — including the ability to use smaller wire and a lower voltage drop — and are particularly attractive for larger boats with high-power requirements. As with hydraulics, unless your boat already utilizes a 24-volt system onboard, a 12-volt system usually means a less complex installation, as the thruster can often be wired directly into your boat's existing system. For that reason, 12-volt DC systems are more commonly found on midsize boats.

A typical electric thruster installation involves either running cables of sufficient size to minimize voltage drop from an existing battery bank, or installing a dedicated battery in the vicinity of the thruster along with a method of charging it. As they likely won't be used at the same time, a third option might be piggybacking off an electric windlass circuit.

A dedicated battery installed close to the thruster has a few advantages. Keeping the battery next to the thruster minimizes voltage drop due to the shorter cables, while the closed circuit provided by a dedicated battery ensures other DC-powered systems and equipment won't be affected by voltage drop when the thruster is in use.

While each of these systems will work if properly designed, the choice typically boils down to installation obstacles, space, and expense (the cost of those heavy cables as compared to a dedicated battery and charger, for example).

Tunnel Bow Thruster Or External Unit?

Tunnel-mounted bow thrusters require a tube or tunnel to be installed through the hull below the waterline, with the unit's prop(s) located inside. For best performance, the installation tube has to be placed as far forward as possible, yet deep enough below the waterline to generate maximum thrust and avoid sucking air, two competing requirements not always possible on boats less than 30 to 35 feet.

A single prop, tunnel-mounted bow thruster.

The need to cut two large holes in your bow and the installation of the tube itself add significantly to the overall costs of the project. The drag produced by the installation can also be a concern to some, although the reduction in speed will typically be less than half a knot. As to tube size, you'd think bigger is better, but a smaller-diameter tunnel actually has a number of advantages over larger ones. In addition to the obvious benefit of requiring you to cut smaller holes into your hull, a smaller tube can be installed farther forward, which increases the distance between the thruster and the pivot point of the vessel. This increased leverage means greater turning force, a plus when moving larger vessels.

With planing hulls, being able to place a smaller-diameter tube farther forward may even be enough to locate the tube so that it's completely out of the water while the vessel is underway, which reduces both drag and fuel consumption. Finally, a smaller, shorter tube has less water inside it, which reduces weight, increases buoyancy, and improves fuel economy.

Externally mounted units are an attractive alternative for boat owners who have internal layout restrictions that prevent installation of a tunnel-mounted bow thruster or for those who simply cringe at the thought of cutting large holes in their hull. One external brand, the Yacht Thruster, requires drilling a one- to two-inch hole (depending on the size of the unit chosen) to attach it via a threaded pipe, which is also used to route cabling. Another external option is the Sideshift bow thruster, which mounts to a vessel's stem and uses no holes below the waterline in its installation. In fact, the manufacturer states it can be installed while the boat is in the water. These units, while simpler to install, are also exposed, making them more vulnerable to impact damage.

Single Or Dual Propeller?

Another consideration when selecting a bow thruster is whether to go with a single-prop unit or a dual, counter-rotating-prop version. Single-prop units cost less than comparably sized dual-prop versions; however, the dual-prop units are more efficient. Counter-rotating props produce roughly 40 percent more thrust than a single-prop unit while using the same amount of horsepower. With single-prop units, a lot of energy is lost in the swirling motion of the water. Counter-rotating units, where the second prop is spinning in the opposite direction, are able to recapture and refocus the energy of this swirling water to increase their maximum thrust. Another plus for dual-prop units is that smaller props and tubes can be used to produce the same amount of thrust, compared to a single-prop unit. Smaller tubes, as discussed earlier, mean better positioning and control.

Better Control = More Fun

The ability to competently and confidently maneuver a vessel (particularly a single screw vessel) in challenging conditions is an art form, one that doesn't come in a flash of inspiration. It takes practice. To many, myself included, nothing beats the satisfaction of melding the effects of wind, current, and the knowledge of your vessel's handling characteristics into a successful docking maneuver under challenging circumstances. That said, a bow thruster is simply another tool — one of many that boat owners use while on the water in their best efforts to get from point A to point B as safely and with as little stress as possible. I don't view their use as some sort of crutch to my boathandling skills. They're like a can of bear pepper spray. If you've ever really needed one — and had it to use it — you're a convert for life.

Product Benefits

Yacht Thruster is a German quality/Swiss precision designed, engineered and tested system manufactured to provide durability and performance with almost triple the operating time of a comparative electric boat thruster system. 25 minutes an hour, plus a 3-year warranty. Yacht Thruster requires no maintenance other than bottom paint and the motor is completely sealed.

Easy Installation

Requires drilling of only three small holes to assemble, which are sealed tightly with a special rubber sealant. No fiberglass work is necessary.

Space Saving

The complete drive unit is very compact and placed externally, saving valuable boat space. Only the operating and control elements, as well as the power supply remain inside the boat.

Minimal Noise

About 80 % noise reduction is obtained by the external placement of the engine. this also results the elimination of possible border cavitations.

Optimal Efficiency

Optimal efficiency results from a shorter transverse channel and ideal leverage which is created by deeper and more distant positioning away from the pivot point. Typically giving up to 40 % higher efficiency than with conventional systems.

Long Runtime

The external placement of the unit gives a more efficient water cooling and allows much longer duration per cycle of the unit than with traditional bow and stern thrusters.

Optimal Design

Hydrodynamic shape, very short flow-channel and ideal placement reduce the water resistance to a fraction compared to conventional systems. There is no perceptible loss of speed.

Simple and Quick Installation

Virtually no resistance in the water.

Tank testing proves that water resistance under power is less than .09% (nine hundredths) power loss, under sail is .05% (five hundredths) loss under sail compared to a tunnel thruster at 10% sail handicap, and equivalent to the drag of only a folding propeller.

Utilizes approximately ½ the amperage of an equivalent LBS thrust tunnel thruster and Minimizes battery consumption Yacht Thruster Nominal current.

Specifications - Duplex Thruster Models

Model 600d (duplex) - boats from 52 - 66 feet (bow install) / 52 to 60 feet (stern install).

The system control center

• Provides delay between drive directions.
• Monitors solenoid functions to reduce the chance of solenoid lock-in.
• Will stop the thruster in case of a locked-in solenoid, without extra user action and even without controlling the main switch.
• Uses the same components as the other Side-Power series and can be combined with any other Side-Power thruster.

Sailboat Installation Positioning

Optimal position for external Yacht Thruster installations:

• Bow Thruster (B)
• Stern Thruster (S)

On round chines there is no/limited necessary GRP work.

Motor Yacht Installation Positioning

• Stern Thruster under swim platform (S1)
• Stern Thruster on “vertical transom” (S2)

On hard chines a fiberglass adaptor may be necessary for installation.

Adaptor Installation

Installation of an external Yacht Thruster is quick and easy. Simply drill a 50 mm diameter hole through the hull for the S/S through-hull fitting (attached to the thruster) which also feeds the required wiring. This through-hull fitting is supplied with a watertight seal which eliminates the need of additional fiberglass work. Also supplied as part of the installation kit are S/S rods to be bolted through two 18 mm pre-drilled holes. This also includes watertight seals and provides ultimate security and rigidity of your external yacht thruster installation.

The front mounting bolts are also secured from the vessels interior and provide a watertight seal.

Special Watertight Sealing

The unique seals provide a permanent watertight solution.

Hi-Tensile Aluminum

Our thrusters are milled from solid blocks of hi-tensile aluminum for incredible strength and durability.

The BOW PRO Thruster Family

Control at your fingertips.

When you are enjoying a day on the water, your focus should be on enjoying every second of the boating season. Relish the time spent with family and friends … or perhaps in pursuit of your next big catch! It should not be spent worrying about docking your boat at the end of the day.

Manoeuvre your boat the way you want

With a BOW PRO on board, you can take away the worry and be confident in your docking skills. With a thruster at your disposal, you can manoeuvre your boat the way you want. A VETUS thruster gives you sideways control of your boat so you can precisely position the bow and the stern of your boat. Even in less-than-ideal conditions, you are always in full control of your boat.

Not all thrusters are equal. Traditional thrusters offer two modes: on and off. Our BOW PRO thrusters offer full proportional control. This means you get to decide how much thrust you need – a little or a lot. And, with VETUS’s innovative DC-to-DC charging technology, you can be confident that your thruster will always be ready to use as much as you need, without fear of overuse or overheating issues.

The one-of-a-kind thruster

You can even take your control a step further with the available lock-and-hold feature. Hold your boat in place while you handle the lines, allowing the rest of the family to relax.

Thrusters are not just for docking. Having total control of your boat is important in any tight situation or when handling your boat with a marlin on the line.

Perhaps the best part of a BOW PRO thruster is the maintenance-free, brushless induction motor. Less maintenance means less hassle and more carefree time out on the water.

Thrusters can take the stress out of docking by giving you sideways control of the movement and position of the bow and the stern of your boat. They work by rotating a propeller in a submerged tunnel or a housing mounted athwartships and located near the bow and/or the stern.

The VETUS BOW PRO is a one-of-a-kind thruster, which is standard fully proportional controlled. This thruster is equipped with brushless induction motors. Therefore the bow / stern thruster motor is maintenance-free and has much longer runtimes compared to conventional DC thrusters

The induction motor is controlled by the VETUS MCV motor controller. The built-in over-temp and low battery protection, combined with the brushless induction motor make the BOW PRO thruster series highly resistant to abuse and ideal for the most demanding boater in the most difficult manoeuvring situations

Revolutionary concept matched with proven technology

The BOW PRO is available in several propeller and tunnel diameters and powerful enough to turn your runabout in the desired direction. Recommended battery sizes for the BOW PRO series are slightly larger than advised for conventional DC thrusters. With these larger batteries you can take full advantage of the motor efficiencies, which results in longer run-times
