RS E10: The Electric Yacht Fin Stabilizer

Where high speeds meet high stability. The RS E10 is RotorSwing's fully electric fin stabilizer: the perfect fit for higher speed vessels from 12 to 40 meters, built on 25 years of expertise in fin stabilization.

The RotorSwing RS E10 is a 100% electric yacht fin stabilizer for higher speed motor yachts from 12 to 40 meters. Its fins deliver powerful roll damping at cruising speed and remain effective at ZeroSpeed, with fin blades available from 0.7–2.0 m².

Built for the fast end of the range

Rotors own the low-speed story. Fins own speed. The faster the water passes the blade, the more force the RS E10 converts into stability, which makes it the natural choice for higher speed motor yachts and semi-displacement hulls: yachts that cruise quickly and want the calm to keep up.

The blade itself is where the refinement lives: an advanced hydrodynamic profile designed to maximize lift and stability, driven by high-torque technology built around RotorSwing's in-house gearbox for a precise damping response. The full mechanism has its own page: yacht stabilizer fins, explained.

And deliberately, no speed ceiling is printed here. The RS E10 is designed for higher cruising speeds; your yacht's specifics decide the rest during specification.

Choose your configuration

Like the rotor systems, the RS E10 is available in two configurations:

Underway

delivers roll damping while cruising, the capability most owners use for the most hours.

Underway + ZeroSpeed

adds stabilization at anchor. At ZeroSpeed the fins generate their own water flow through active rotational movement rather than relying on the yacht's forward motion, so stabilizing force stays available with no forward motion. That same motion helps prevent anchor-walking, keeping the yacht in position instead of wandering around the anchor.

One honest note on the family logic: the fins do not carry the Adaptive Rake function. Rake is a rotor technology; the RS E10's answer to drag is its streamlined, low-resistance profile.

Main benefits

From the specification sheet:

RotorSwing fins come in sizes ranging from 0.7 m² to 2.0 m², matched to your yacht during specification.

One platform, combined if you want both

For owners who want maximum stabilization at speed and maximum comfort at slow cruising and rest, the RS E10 can be combined with the rotor systems in a single installation: fins take the high-speed work, rotors deliver the ZeroSpeed performance. Compare the whole family on the full product range.

Specifications

Full technical specifications for the RS E10 (dimensions, power, weights, installation requirements) are available on request, matched to your yacht during specification.

Whether the RS E10 fits your yacht comes down to hull type and cruising speed. Tell us both and a RotorSwing engineer will confirm it honestly, including when a rotor would serve you better.
