Detailed description

Designed for boats from 8 to 11 meters (27-37 feet), the Sleipner SE50/140S 12V electric bow thruster provides reliable and efficient maneuvering assistance. This system integrates advanced technologies to optimize safety, control, and performance, facilitating harbor maneuvers and navigation in tight spaces.

Performance and technical specifications

The SE50/140S 12V thruster delivers 62 kg of thrust at 12V (50 kg at 10.5V), powered by a 12V DC electrical source with a power output of 2.4 kW (3.2 hp). It requires a current of 370A and an ANL 325 fuse, with a minimum battery CCA capacity of 350 (DIN). The internal tunnel diameter is 140 mm (5.5 inches), and the unit weighs 15 kg. Its single-propeller propulsion system is optimized for narrow bows.

Integrated technologies for precise maneuvering

The Sleipner SE50/140S 12V integrates several features. The Intelligent Power Control (IPC) minimizes the delay between direction changes, reducing mechanical wear and monitoring solenoid functions for automatic shutdown in case of blockage. The overheat protection automatically shuts down the system if internal temperatures rise to prevent damage. Galvanic isolation of the underwater components eliminates stray currents, protecting against corrosion. The sealed gearbox lubrication system, factory-filled with ceramic and carbon surfaces, ensures extended service life and reduced maintenance. The five-blade Q-Prop propeller, with angled blades, reduces noise by 20 to 40% while maintaining thrust efficiency. Plug & play analog connectors with color coding simplify electrical installation, and the Safe Startup function requires a two-button activation to prevent accidental starts.

Flexible installation and scalability

The thruster’s design allows flexible installation: it can be mounted at any angle within the tunnel, and the electric motor can be rotated 90 degrees on its bracket, adapting to various hull configurations. The system is compatible with upgrade options such as the PRO™ variable-speed control and remote controls, enabling finer management and simplified integration with joystick systems via S-LINK™.

Expert opinion

« Technical analysis of the Sleipner SE50/140S 12V bow thruster »

The Sleipner SE50/140S 12V bow thruster is a critical piece of equipment for sailboat owners of 8 to 11 meters seeking to optimize their vessel’s maneuverability. It simplifies harbour manoeuvres and navigation in tight spaces, thereby increasing onboard safety and comfort. Its design prioritizes reliability and longevity, featuring galvanic isolation of underwater components to prevent corrosion, and the Intelligent Power Control (IPC) system that protects the motor from overloads and solenoid lockups.

Installing this model provides notable flexibility: the electric motor can pivot 90 degrees, and the thruster can be mounted at various angles within the tunnel, making integration into hulls with diverse space constraints easier. It is critical to note that while the connectors are "plug & play," the overall system sizing (batteries, wiring, ANL 325 fuse protection recommended) is essential. A prior professional assessment is mandatory to ensure optimal performance and prevent under-sizing that could impair operation or shorten the device’s lifespan. The Q-Propeller solution, with its five asymmetric blades, delivers a significant noise reduction of 20 to 40% compared to standard propellers—a key comfort feature. The upgrade option to the PRO™ system with variable speed control, compatible with Sleipner models from 1999/2000 onwards, also enhances manoeuvring precision and offers advanced functions such as dock-keeping.

Frequently Asked Questions

Need help? Contact us

What is the Sleipner SE50/140S 12V bow thruster used for?

The Sleipner SE50/140S 12V electric bow thruster is designed to simplify your boat’s handling, particularly during docking and departure, by enabling precise lateral movement of the bow. It significantly improves vessel control in tight spaces or in strong winds.

For which type of sailboat is the SE50/140S 12V thruster recommended?

The Sleipner SE50/140S 12V bow thruster is ideally suited for boats measuring between 8 and 11 meters (27 to 37 feet).

Does the SE50/140S 12V bow thruster feature variable speed control?

The SE50/140S 12V bow thruster is not supplied as standard with the PRO™ variable speed control. However, it can be upgraded to this feature to provide smoother and more precise maneuvering. PRO™ upgrade kits are available for most Sleipner (Side-Power) DC 12V and 24V models manufactured from 1999/2000 onwards.

What is the required tunnel diameter for installing the SE50/140S 12V bow thruster?

The Sleipner SE50/140S 12V bow thruster requires a 140 mm (5.5 in) tunnel diameter for installation.

What is the minimum recommended battery capacity (CCA) for the SE50/140S 12V thruster?

To ensure optimal operation of the Sleipner SE50/140S 12V bow thruster, the battery must have a minimum capacity of 350 CCA (DIN).

Is the SE50/140S 12V thruster propeller designed to reduce noise?

Yes, the SE50/140S 12V thruster is fitted with the Q-Prop propeller. This five-blade, skewed propeller is specifically designed to reduce noise levels by 20 to 40% in real-world installations, and up to 75% in controlled tests, while maintaining or improving thrust performance.

Is the SE50/140S 12V bow thruster compatible with the PRO™ variable speed control system?

Yes, the Sleipner SE50/140S 12V bow thruster is compatible with an upgrade to the PRO™ variable speed control system.

Most Sleipner (Side-Power) DC 12V and 24V models manufactured from 1999/2000 onwards can be upgraded to the PRO™ variable speed control. This feature provides smoother, quieter, and more precise maneuvering. It also includes a hold function for twin systems, allowing the boat to be gently held against the dock with a single button press, and facilitates integration with joysticks.

However, the SE50/140S 12V model is not supplied by default in the PRO™ version. An upgrade is required to access this advanced feature.
