Side-Power SRL100 Retractable Electric Bow Thruster, 24V — 100 kg On/Off Marine

SRL100 Retractable Thruster 90° Motor 24V | 220LB Thrust

The SRL100 Retractable Thruster 24V is a premium 24V bow thruster engineered for yachts and sailing vessels that demand exceptional maneuverability, compact installation, and long-term reliability. Developed by Sleipner (Side-Power), this model combines advanced mechanical design, smooth deployment, and powerful thrust for total control in all sea conditions.

Delivering 100 kg (220 lb) of thrust, it offers precision handling for docking, mooring, and navigating confined areas, ensuring safety and stability even under strong wind or current. Its innovative flange-mounted casing allows easy installation across a wide range of hull materials, making it ideal for both new builds and retrofit projects.

Retractable Electric Bow Thruster

The retractable electric bow thruster system of the SRL100 stands out for its intelligent design and mechanical strength. The thruster unit is housed in a sturdy casing that bolts directly to a base plate, eliminating the need for complex laminating or reinforcement work. This simplifies installation, particularly in production boats or vessels made of fiberglass, aluminum, or steel.

Equipped with a high-speed actuator, the SRL100 deploys or retracts in just 3–5 seconds, offering instant response when maneuvering. The compact vertical motor mount ensures stability by minimizing stress on the assembly, even in rough seas, while reducing the impact forces typically experienced by angled motor installations.

This efficient layout also makes the SRL100 lighter, quieter, and easier to maintain. When retracted, the thruster sits flush with the hull, minimizing drag and preventing marine growth on the propellers — ensuring consistent performance and a longer lifespan.

Marine Bow Thruster

As a highly reliable marine bow thruster, the SRL100 reflects Sleipner’s renowned commitment to safety and engineering excellence. Every component is designed for long-term reliability, from its sealed, lifetime-lubricated drive system to its galvanically separated motor casing, which protects against corrosion.

The S-Link™ digital control system ensures seamless communication between the thruster, control panel, and accessories. Its Plug & Play connectivity simplifies installation and allows quick diagnostics and integration with Side-Power control stations, remotes, and automation modules.

Safety is an integral part of the SRL-series design. The shear pins on the hatch prevent hull damage in case of mechanical overload, while the IPC (Intelligent Power Control) system provides automatic current monitoring and protection against overheating or short circuits.

The result is a compact, efficient, and incredibly durable system suitable for vessels up to 55 feet in length that require reliable performance in all weather conditions.
