AtZeroSpeed

The latest and most complete invention from RotorSwing Marine is the ZeroSpeed version. This Patented roll damping system uses the Magnus effect force when the vessel sits at anchor or is just afloat. By swinging the rotors back and forth, the RotorSwing produces the same powerful roll damping lift forces as when it were in DRIVE position while cruising. This ZeroSpeed version also performs extremely well while cruising up to 25 knots!


As you will see in this video, the ZeroSpeed function of the RotorSwing system is very powerful. The ZeroSpeed roll damping function is very useful while relaxing in a bay with yachts passing by or to counter an unsuspected storm. The system is very quiet and adaptive. For those who would like to experience ZeroSpeed for themselves, email or call us to schedule a test ride!


Roll Damping while at Anchor

During the ZeroSpeed mode, the rotors continuously spin while the arms are swung back and forth to create flow. Since the rotors are placed much more horizontally to the waterline, over 95 percent of the lift force is applied to counter the vessel’s roll motion. This is a huge benefit compared to generic fin stabilizers which are positioned under a rather steep angle! The steering effect of this roll damping system is therefore also almost unnoticeable.

The roll damping of this RotorSwing ZeroSpeed system is very powerful and simply has to be felt in order to truly belief it. Not only can the crew enjoy a much more stable anchorage in a choppy bay or cove but also while being hindered by the wash from fast cruising or larger vessels. 


Roll damping for vessels at anchor or adrift is gaining popularity. But until now, superyacht owners were the only ones who were able to afford such a system. The inventor of this patented ZeroSpeed system has over 50 years of experience in this superyacht industry with its partner Quantum Controls Holland. After hundreds of successful fin installations, the Maglift Rotor system is also gaining super-yacht popularity. For yachts up to approximately 35 meters (115′), RotorSwing Marine has invented an affordable electric ZeroSpeed system.

The installation of the AtZeroSpeed RotorSwing is simple. Since there is no steering effect generated, placement is extremely flexible. The system installation is often performed towards the aft of the ship.

Our electric driven RotorSwing 140 is simply the most powerful and diverse stabilization system on the market.
