    S-LINK™

    S-Link™ is a CAN-based control system used for communication between Sleipner products installed on a vessel.

    • Compact and waterproof plugs
    • Keyed and color-coded connectors to ensure correct and easy installation
    • Different cable lengths, extenders and T-connectors makes the system scalable and flexible to install

    Q-PROP™

    The Q-PROP™ has measured noise reductions of up to 75% in controlled environments. The five-bladed skew propeller reduces noise levels while maintaining exceptional efficiency. Some thruster models even see an increase in thrust power. 

    • The expected noise reduction in average installations: 20-40%
    • Upgrade kits are available for most Sleipner thruster models with special adaptors

    PRO™

    A PRO™ thruster system enables you to apply only the necessary power to complete your maneuver. The variable speed control eliminates the noise associated with standard on/off thrusters.

    The system also includes a practical hold-function. In a dual system (bow and stern) a single press of a button will keep you alongside the docks - making docking truly a one-person job. 

    Speed controlled thrusters are the best choice for joystick interaction.​

    INTELLIGENT POWER CONTROL

    Sleipner's patented intelligent power control provides a minimal delay between drive directions to reduce wear of the mechanical parts while monitoring solenoid functions. In the case of a solenoid lock-in, the thruster will automatically stop without extra user action or controlling the main switch.

    OVERHEAT PROTECTION

    When high temperatures are detected, On/off thrusters are automatically shut off to prevent overheating. PRO™ thrusters with speed control provide extended run-time by derating power to maintain temperature within safe levels.

    FLEXIBLE COUPLING

    Flexible coupling protects the product’s driveline by compensating for minor misalignments between the shafts of the thruster motor and gearleg.

    TWIN PROPELLERS

    Twin propellers can provide more thrust than a single propeller system in the same tunnel diameter. We use this system in our mid-range models, where high thrust is required in small tunnel diameters. Due to the compact design and high performance, the twin models have become the thrusters of choice among boatbuilders worldwide.

Item code: SRVP80/185T-24V

SRVP80 PRO™ with variable speed control is a sturdy retract thruster with 80-96 kg thrust, suitable for boats between 35-48 feet.

The thruster is mounted on a flange and has a fast deployment and retraction time. The unit is designed for vertical installation, making it perfect for boats with available height space. 

A remote control is a popular accessory. See some of the important product and safety features below.

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.

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 650 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 386 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.
