Steel Motorboat / Cruiser: Navigating Comfort with Control

Steel motorboats are a true Dutch classic, ideal for exploring the scenic waterways of the Netherlands. These robust and reliable boats have been popular for decades, offering comfort and reliability for those looking to enjoy nature from one mooring to another. However, there can be some stressful moments—waiting for bridges, controlling the boat in a lock, or maneuvering into a tight berth in a crowded marina.

Many of these boats are equipped with a traditional bow thruster—a tunnel welded into the bow, with a propeller prone to getting entangled with aquatic plants. Noise is also a known issue since the sound resonates strongly in a steel hull. However, these problems become a thing of the past with a Jet Thruster system.

Jet Thruster: Silent and Controlled Maneuvering

The Jet Thruster pump unit is installed centrally in the boat, typically under a seat or in the engine room. The key is to place the pump below the waterline. A minimum depth of 30 cm at the chosen location is required. Thanks to the flexible placement options, it is almost always possible to install a Jet Thruster.

A flexible, spiral-reinforced rubber hose connects the pump to either the bow or the stern. Near the bow or stern, a distribution valve—also known as a 3-way valve—directs the water flow to the port or starboard side, ensuring precise and efficient control.

Installation Options

After the distribution valve, the hose is connected to the nozzle. For steel boats, there is an option to weld in a steel nozzle, but you can also choose composite nozzles, available in six standard angles. The nozzle is installed 7 to 10 cm below the waterline, as far forward in the bow as possible, perpendicular to the boat’s centerline. Ensure that the nozzle is placed horizontally, although a slight downward angle of a few degrees is acceptable.

Once installed, the nozzle is fitted with a 2” stainless steel ball valve. The hose is connected to this ball valve. All components are robust, durable, and of industrial-grade quality. Despite the low system pressure (only 2 bar), we opt for heavy-duty materials to ensure longevity and reliability.

Flexible Solution for Every Type of Boat

he Jet Thruster system can be integrated in various ways: from the pump to the hose, distribution valve, and then to the nozzle (or through-hull fitting). There is no standard configuration, which is what makes the Jet Thruster system so adaptable. Even in existing boats or vessels with limited draft, the system can be installed. You can opt for just a bow or a combination of bow and stern systems.

If you already have a bow thruster but find a stern thruster difficult to install, the Jet Thruster offers the perfect solution. You can easily combine a Jet Thruster at the stern with your existing bow thruster. As long as the pump is below the waterline and the nozzles can be placed 7-10 cm under the water, the Jet Thruster is the ideal way to make docking and maneuvering a lot more relaxed.

Key Advantages of the Jet Thruster:

- No Clogging: No propeller to get caught in aquatic plants.

- Silent and Powerful: No resonating noise inside the hull.

- Flexible Installation: Suitable for both existing and new boats.

- Enhanced Control: Makes maneuvering easier, even in tight harbors.

- Peace of Mind: With the Jet Thruster, you can maneuver with confidence and enjoy your time on the water stress-free.

Polyester Sailing Yacht 30-60 Feet: Precision Control in Challenging Conditions

Since 2010, we have been producing and supplying Jet Thruster systems for almost every type of sailing yacht. Our systems are particularly suitable for yachts in the 30-60 foot range, even in high winds of Beaufort 5, 6, or 7. When wind speeds increase, a sailing yacht can quickly go off course, requiring more steering skill to safely maneuver in a marina. This is when a Jet Thruster becomes an indispensable tool.

While some shipyards offer bow thrusters as a factory option, many owners choose to install a Jet Thruster later due to the unique benefits our system provides.

Overcome Wind Challenges with a Jet Thruster

A Jet Thruster gives you precision control, even in high winds. Modern sailing yachts are often wider than classic designs, resulting in low draft in the forward section, making conventional bow thrusters difficult to install. Traditional bow thrusters require a minimum installation height of 1.5 times the diameter of the tunnel, which can lead to the propeller being placed too close to the keel, reducing its effectiveness.

No More Propeller-Related Issues

Unlike conventional bow thrusters, the Jet Thruster system uses small, efficient nozzles instead of large tunnels. This reduces drag during sailing and eliminates the risk of entangled ropes or plants. The system’s small nozzles can be placed far forward in the bow, optimizing the leverage effect compared to traditional solutions.

Key Benefits for Sailing Yachts:

- Optimized Weight Distribution: Components can be evenly distributed across the boat.

- Minimal Space Requirements: Ideal for modern designs with limited interior space.

- Superior Control: Perform precise maneuvers, even in tight marinas.

- No Propeller Noise: Smooth and quiet operation.

- In-Water Servicing: Can be serviced without lifting the boat out of the water.

With a Jet Thruster system, sailing becomes less about managing complications and more about enjoying the experience. It’s a high-performing, easy-to-install solution that adapts to a wide range of vessel designs.

Sloops: The Ideal Solution for Tight Maneuvers

The sloop is a uniquely Dutch design, tailored for the intricate network of lakes, canals, and waterways throughout the Netherlands. Many owners value the ease of cruising on these stable boats, but even experienced boaters can face challenges. Flat-bottomed sloops with minimal draft can easily drift off course, especially at low speeds or in windy conditions, making docking a stressful endeavor. A Jet Thruster system provides an elegant solution, giving you full control during tight maneuvers.

Sloop Evolution: From Lifeboats to Modern Cruisers

Originally designed as robust lifeboats with basic handling capabilities, today’s sloops have evolved into luxury dayboats equipped with modern comforts. However, traditional handling issues persist due to their flat bottoms and shallow draft.

Catamarans: Superior Control for Challenging Maneuvers

Catamarans have gained immense popularity in recent years, especially among charter companies in the Mediterranean. With their wide beams and large sail areas, catamarans can be tricky to control in windy conditions. The twin engines provide some maneuverability, but a Jet Thruster system can greatly enhance control, making docking easier even in crowded marinas.

Overcome Wind Challenges

Catamarans often have a large wind-catching surface, making them vulnerable to being pushed off course by gusts. A Jet Thruster system installed at the bow or stern provides precise control, allowing the captain to maintain the desired heading even in strong winds.

Compact Nozzle Design for Shallow Drafts
