Detailed description

Designed for 13 to 19-meter yachts, the Sleipner SRV130/250T 12V retractable thruster is a bow and/or stern maneuvering system. It delivers 130 kg of thrust at 10.5VDC and up to 160 kg at 12VDC, with a power output of 6.5 kW (8.7 hp) at 10.5V, making harbor maneuvers and docking easier in tight spaces.

Performance and design

The SRV130/250T 12V uses a twin-propulsion system with two "Q-PROP™" five-blade skewed propellers made of fiberglass-reinforced composite. These propellers reduce noise by 20 to 40% in real-world conditions and up to 75% in controlled tests, while maintaining or improving thrust performance. The thruster requires a minimum battery capacity of 750 CCA SAE and a 500 Amp fuse (SMANL500). Its net weight is 82 kg with a 250 mm tunnel diameter.

Integrated technologies and safety

This thruster integrates the S-Link™ control system, based on CAN, providing bidirectional communication and Plug & Play wiring for simplified installation. The Intelligent Power Control (IPC) minimizes delays between direction changes, reducing mechanical wear and monitoring solenoids. Overheat protection automatically shuts down the system if temperatures rise too high. The gearbox lubrication is sealed for life with mechanical seals. Immersed parts are electrically isolated to prevent galvanic corrosion. Additional safety mechanisms include a pressure sensor that automatically retracts the thruster if boat speed is too high, and electronic protections against sudden direction changes.

Installation and operational flexibility

The SRV130/250T is installed vertically, with a flange, and features quick deployment/retraction. It requires a minimum depth of 125 mm to the top of the tunnel and 250 mm to the center of the tunnel. A PRO™ option is available, offering variable speed control for more precise maneuvering and a hold function for twin systems, allowing the boat to be held against the dock with a single button press. A flexible coupling protects the propeller shaft by compensating for minor misalignments.

Expert opinion

« Control and discretion for yachts: Analysis of the Sleipner SRV130/250T thruster »

The Sleipner SRV130/250T 12V retractable thruster is an advanced maneuvering solution designed specifically for sailboats and medium to large vessels, typically between 13 and 19 meters. Its retractable nature is a major asset for owners concerned with hydrodynamics or aesthetics, allowing the system to be concealed when not in use, thereby reducing drag and protecting the mechanism from debris. This feature sets it apart from fixed tunnel thrusters.

Installing this type of thruster is more complex than a standard tunnel model. It requires rigorous planning for mechanical hull integration, routing high-current power cables (up to 500A), and setting up a dedicated battery bank capable of delivering 750 CCA SAE. The system demands significant space for the retraction mechanism and motorization, which must be accounted for during the boat's initial design or refit. The flexibility of installation with a separate base can simplify integration on hulls made of various materials.

Its practical value lies in providing precise and silent maneuverability for large vessels, where lateral thrust is critical for docking or dynamic positioning. The Q-PROP™ and S-Link™ technologies, combined with Intelligent Power Control (IPC), ensure not only discreet operation but also increased reliability of mechanical and electronic components, extending the system's lifespan. The PRO™ option with variable speed is a significant advantage for fine maneuvering and integration with joystick systems, offering proportional control that is often decisive for large vessels.

Although the initial cost is high, the robust design (sealed lubrication, galvanic separation, flexible coupling) and multiple safety features (overheat protection, speed sensor) make it a durable investment. It is imperative to have the installation and sizing validated by a professional to ensure performance and safety.

Frequently Asked Questions

Need help? Contact us

What are the main safety and performance features of the SRV130/250T 12V thruster?

The SRV130/250T 12V bow thruster integrates several advanced features for safety and performance:

Intelligent power control: Minimizes mechanical wear and ensures automatic shutdown in case of solenoid lock-up.Overheating protection: Automatically detects high internal temperatures and shuts down the system to prevent damage.Galvanic isolation: Electrically isolates the immersed components from the onboard system to prevent corrosion.Secure start-up: Requires a two-button activation to prevent accidental starts.

Is the SRV130/250T 12V bow thruster designed to be quiet?

Yes, the SRV130/250T 12V thruster is equipped with Q-PROP technology. This five-blade, skewed propeller reduces noise by 20 to 40% in real-world installations and up to 75% in controlled tests, while maintaining or improving thrust performance.

Can the SRV130/250T 12V bow thruster be used with a variable speed control system?

Yes, the SRV130/250T 12V thruster is compatible with the upgrade to Sleipner’s PRO™ variable speed control system. This allows for smoother, quieter, and more precise maneuvering, and may include a hold function for twin systems.

Is the SRV130/250T 12V bow thruster compatible with Sleipner S-LINK™ control systems?

Yes, the SRV130/250T 12V thruster is fully compatible with Sleipner’s S-LINK™ intelligent control system, enabling advanced integration and management within your onboard system.
