How our systems work

Yacht Stabilization Technology

Every RotorSwing system exists for one reason: so the movement of the water never decides how you spend your day on it. This is the technology that makes that possible.

Explore each technology below.

RotorSwing builds 100% electric yacht stabilizers that reduce roll both while cruising and at anchor, using patented Magnus-effect rotor technology and electric fin technology, for motor yachts from 12 to 40 meters.

Two technologies. Every situation.

Some yachts spend their life cruising. Others spend most of it at anchor. Most do both. That is why the platform is built on two complementary technologies rather than one.

Magnus-effect rotors

create stabilizing force with spinning cylinders in the water. They are strongest at lower cruising speeds and, in ZeroSpeed configuration, when the yacht is not moving at all.

For owners who want maximum stabilization at speed and maximum comfort at anchor, rotors and fins can be combined in one installation. The fins take over at speed; the rotors deliver the ZeroSpeed and slow-cruising performance.

Two modes: Underway and ZeroSpeed

Underway means while cruising. RotorSwing rotors deliver roll damping from just 3 knots.

How Underway stabilization works

ZeroSpeed means exactly that: zero forward speed. RotorSwing's patented Rotor ZeroSpeed technology stabilizes a yacht at anchor, with no forward motion required.

100% electric, by design

No hydraulics. No oil. No electronics below the waterline. Every RotorSwing system is fully electric, which is why owners describe the experience as switching it on and forgetting it is there.

What 100% electric means

Patented refinements

The details are where decades of engineering show. Adaptive Rake, patented by RotorSwing, automatically angles the rotor to reduce drag and power consumption at higher cruising speeds without giving up stabilization.

What it feels like on board

The technology is only ever a means to an end. One owner, after switching his system on and off twice to feel the difference:
