ANY SPEED
Vector Fins™ is the only top-performing stabilizer system for both cruising and at anchor use. The fins’ concave shape creates multilateral force direction improving the stationary positioning of a vessel while at anchor. The uniqueness of the design also becomes evident while underway as it improves in effectiveness as speed increases. Sea trials have proven that Vector Fins™ are up to 50% more efficient at anchor and capable of reducing the uncomfortable rolling motions of the vessel by up to 95% while cruising.

360° INSTALLATION
Designed to fit in small and challenging installation areas, the Vector Fins™ unique cone shaft design allows you to utilize the space onboard to install the actuators in any direction and insert the fins into the position you require.
Item code: SPS40E-24/48V
The SPS40E actuator is the driving force behind Sleipner’s Vector Fins™, delivering precise stabilization for compact yachts in the 14–18 meter range. Known for being the most compact and energy-efficient on the market, it integrates easily into yacht layouts, controlling fin movement to reduce roll and provide a smoother, more comfortable ride.
Powered by 24V or 48V DC, the SPS40E uses advanced algorithms to continuously adjust fin positioning in real-time, ensuring stability and comfort even in changing sea conditions.

Peak power per actuator: 3,6kW
Notice:
This depends on many factors, including the boat's roll period, the size of the stabilizer system for the boat, and the sea state.
When designing the power supply system, it must be able to deliver enough power for both the stabilizer system and any other connected equipment that will be operating at the same time at their maximum power draw.
Additionally, the system must handle rapid power changes from the stabilizers, which go from zero to full power twice during each roll cycle of the boat.
Once the total peak power demand is known, use the boat’s roll period and choose a typical operating scenario (e.g. large waves, medium waves, or calm conditions). Typically, small to medium waves are the most common conditions to anchor comfortably in. Then decide how long the system should run from the battery bank without running a generator.
This information allows the power system supplier to calculate the required battery capacity (in amp-hours), battery technology and charging capacity. A safety margin should be included to account for battery aging and reduced performance over time.
Note that the above listed values is for a specific sea state scenario running both actuators constantly at the stated load. Actual consumption will change according to the change in sea state such as wave height, length and frequency. These values are therefore to be considered as guidelines only.

A legacy that commits
We’ve lived and worked with the unruly sea for a hundred years. That’s why we develop important features that enables a boat to handle the sea better – that enable you to enjoy your boat, at anchor and at full speed. That is why you wanted a boat, isn’t it?
-
Beautiful engineering
The technology in our solutions is world-class. We know, because we’ve developed it ourselves, just as we manufacture every solution, and follow them until their fixed to a hull, ourselves. This meticulous attention to detail is why your day out always will be better with a Sleipner aboard.
