Side-Power SRP100/185T Retractable Electric Bow Thruster, 24V — 100 kg Marine

SRP100/185T Retracting Proportional Thruster 24V | 220LB Thrust

The SRP100/185T Retracting Proportional Thruster 24V represents the pinnacle of precision and performance in the world of 24V bow thrusters. Designed and built by Sleipner (Side-Power), this advanced retractable system provides exceptional control, power efficiency, and silent operation for yachts that demand superior handling in any marine environment.

With up to 100 kg (220 lb) of thrust, the SRP100/185T delivers unmatched maneuverability during docking, tight turns, and anchoring operations. Thanks to its proportional control system, captains can select exactly the amount of power required for every situation—ensuring total control in all sea and weather conditions.

Perfect for vessels where tunnel thrusters cannot be fitted, this model combines hydrodynamic design, compact installation, and advanced electronic control into one seamless marine solution.

Retractable Electric Bow Thruster

The retractable electric bow thruster configuration of the SRP100/185T ensures maximum efficiency and protection. When engaged, the unit extends vertically from the hull to deliver powerful, directional thrust; when not in use, it retracts fully, maintaining the vessel’s clean lines and reducing hydrodynamic drag.

This retractable system prevents marine growth, protects the propellers, and keeps performance consistent over time. The innovative pressure-sensing safety feature automatically retracts the thruster if the vessel exceeds its safe speed limit, while the lockout protection prevents operation when partially retracted.

The design also minimizes noise and vibration, making it ideal for modern luxury yachts where comfort and performance must coexist.

Marine Bow Thruster

Built from high-quality marine-grade materials, this marine bow thruster ensures durability and long-term reliability, even under continuous use. Its twin composite propellers and sealed gear housing are engineered to maximize thrust while reducing turbulence and mechanical stress.

The proportional DC control system allows for smooth power adjustments and efficient energy usage, extending battery life and ensuring responsive operation. Integrated thermal protection and flexible motor couplings prevent overheating and mechanical wear, maintaining consistent performance in demanding marine conditions.

Its Plug & Play S-Link™ communication system simplifies installation and allows seamless integration with control panels, remote systems, and automatic switches.
