SRHP320 retract thruster hydraulic G19

Product Description

Retractable thrusters cause no drag

If you have a performance boat, sail, or power, and you’re worried about the smallest amounts of drag, a retractable thruster is a perfect solution for you.

With power ranging from 100-1400 kg for installation in both the bow and stern, Sleipner offers a wide range of hydraulic retractable thrusters designed for commercial vessels and larger leisure boats.

Sleipner’s retractable thrusters work with all types of propulsion systems – DC, AC, and hydraulic – and can be installed in the bow and the stern of the boat. Available as standard (on/off) or PRO™ with variable speed control extending from 80 kg to 300 kg of thrust.

Like all Sleipner products, the retractable thrusters are made with high safety standards. Safety is important in product design, from build quality to ease of installation, to ensure long-term reliability.

There are three versions of the retractable thrusters, one designed to be directly molded in and two designed to be mounted on a flange. The flange can be a mold-in base from Sleipner, or boat builders can use materials suitable for their hull or as part of their hull design.

The flange-mounted models have the thruster unit placed in a casing that can be bolted to a base. This makes installing the thrusters in hulls made from different materials easier. It also simplifies series production, as it avoids the need to mix laminating and engineering jobs.

Quick deployment

The thrusters with a tunnel diameter of 185 mm use one fast and powerful actuator. In comparison, the models with a diameter of 250 mm and 300 mm have two actuators to handle the increased forces while maintaining the same exceptionally fast deployment time.

The retract mechanism

The unique design of the underwater mechanism has only a few, but very solid parts, contributing to the stability of the unit. The unit’s design makes the thruster as compact as possible while enabling safe use of heavier motors on more powerful units. The vertical installation of the motor (SRV) reduces shock forces on the unit in extreme waves compared to motors mounted at an angle.

A hydraulic thruster system

Sleipner offers complete hydraulic systems that are guaranteed to work well together and maintain high quality. These systems include all the necessary parts and are ready to be installed, ensuring the best possible quality.

Using a hydraulic system for multiple functions on a vessel can be a cost-effective choice. Once the main system is installed, adding a new function only requires adding a simple and relatively inexpensive hydraulic valve. This is more efficient and cheaper than using separate electric motors, solenoids, fuses, and battery switches for each function, especially for larger equipment.

Hydraulic valves and motors are also better suited for harsh environments such as the forepeak, bilge, transom, and ignition protection areas. Common hydraulic applications include thrusters, stabilizers, winches, capstans, cranes, and other equipment.

Sleipner’s hydraulic systems are designed to provide excellent performance for the primary components and the flexibility to power multiple additional equipment.
