sleipner Vector Fins

Motor Yacht Stabilisation Perfected

Stabilisers increase the ways you can use your motor yacht. Backed by over a decade of dedicated R&D and proven in over 2,200 installations, Vector Fins™ by Sleipner are the only stabiliser system that is top performing for both cruising and at anchor-use. The fins' patented unique shape reduces drag and improves fuel efficiency, translating more power into actual roll stabilisation, increasing comfort and safety on-board, as-well-as your vessel's value.

Vector Fins™ employ algorithms that adapt perfectly to the rhythm of the sea, providing unwavering stability and a smoother experience onboard. At anchor, enjoy up to 90% roll reduction - outperforming the competition and redefining comfort on the water.

Less Overall Fuel Consumption

Features

Smooth Ride

Enhanced roll stabilization keeps your boat steady, delivering comfort and safety in all conditions.

Fuel Efficiency

The unique fin shape generates lift, reducing drag and improving fuel economy, making faster boats more efficient.

Reduced Drag

More power is directed into stabilization, improving performance compared to traditional flat fins.

Compact & Versatile

The compact actuator design allows seamless integration with any motor yacht, preserving space without compromising performance.

Dual Functionality

Effective stabilization at both high speeds and at anchor, providing comfort whether you’re underway or at rest.

Quiet Operation

Patented noise reduction technology ensures peace and quiet aboard.

Sustainable Performance

With up to 80% less power usage at anchor, Vector Fins™ deliver double the stabilizing force per kW - giving you powerful stabilization with a lighter environmental footprint.

A Patented Fin Design like No Other

Backed by over a decade of dedicated R&D and proven in over 2,200 installations, Vector Fins™ offer a unique approach to motor yacht stabilization. The patented curved fin design channels stabilization forces more vertically, achieving high efficiency with much lower energy use than traditional systems.

Quiet Operation

The patented electric actuator isolates the moving, mechanical high-torque gears and motor from the boat reducing about 92% of structural born noise known to be a challenge for boat owners looking to stabilize their vessels overnight.

Fuel Efficiency

Thanks to the lift generated by the fins, faster vessels benefit from improved fuel efficiency. On average, boats equipped with Vector Fins™ can experience a reduction in fuel consumption, compared to a flat fin design, making them a cost-effective and environmentally friendly choice for long-term use.

Performance at Anchor

Unlike many stabilizer systems, Vector Fins™ are equally effective at anchor. Their advanced design reduces boat roll by up to 90% even when the vessel is stationary, ensuring maximum comfort for passengers and crew, whether at rest or in motion.
