Side-Power SRLP80 Retractable Thruster Unit (24V, 80 kg, Proportional)

The SRLP80 24V Retractable Thruster by Sleipner (Side-Power) is designed for sailors and yacht owners who demand precision, control, and efficiency. Offering up to 80 kg (176 lbs) of thrust, this unit combines proportional speed control with a retractable design, ensuring smooth maneuvers during docking while eliminating drag when cruising.

Thanks to its 90° motor configuration and compact housing, it is the perfect choice for vessels with limited internal space that still require powerful maneuvering assistance.

Small Retractable Bow Thruster Concept

The SRLP80 is part of a new generation of small retractable bow thrusters and stern thrusters designed for modern yachts. Unlike traditional tunnel thrusters that create drag even when idle, retractable units deploy only when needed. Once retracted, the hull remains completely flush, preserving sailing performance and fuel efficiency.

This makes the SRLP80 an excellent choice for performance-oriented sailboats or cruisers where efficiency is critical.

Proportional Control Advantage

Unlike standard on/off thrusters, the proportional control system allows you to adjust thrust power with precision. This results in:

• Smooth, progressive maneuvers in tight marinas.
• Reduced stress on electrical systems.
• Improved control in heavy winds or currents.
• Extended runtime, since full power is not always required.

The “hold” feature also lets you maintain your position against wind or current with just one command — particularly useful when waiting at locks or during solo docking.

Technical Specifications

Performance depends on installation depth, hull design, and battery supply.

Why Choose a Sailboat Stern Thruster?

As a sailboat stern thruster, the SRLP80 offers significant benefits for skippers:

• Docking made simple even in strong crosswinds.
• No permanent drag — retracts when not in use.
• Optimized for 24V systems, commonly found on cruising sailboats.
• Compact footprint, ideal for vessels with limited hull space.
• Low noise and vibration, ensuring comfort on board.

By combining electric proportional control with retractable design, it represents one of the most advanced solutions available for bow thrusters for boats today.

Installation & Integration

• Requires a compatible bow or stern tunnel.
• Easily integrates with Side-Power S-Link™ control cabling.
• Supports joystick docking systems and remote controls.
• Optional upgrades available for on/off SEP thruster conversions.

Accessories & Options

When purchasing the SRLP80, consider:

• Control Panels (standard or joystick)
• S-Link™ cabling and harnesses
• Remote controls (for on/off functions)
• Automatic main switch / fuse holder
• Extra zinc anodes for long-term corrosion protection

Why the SRLP80 Stands Out

The SRLP80 isn’t just another thruster — it’s a proportional, retractable, sailboat stern thruster engineered for sailors who value both performance under sail and docking confidence. With Sleipner’s reputation for durability and innovation, this model is a benchmark in the thruster market.
