RotorSwing Holland is continuously improving its own roll damping systems. In 2018, RotorSwing made great advancements on the ZeroSpeed version in terms of design and functionality. This newest ZeroSpeed version now provides roll damping up to higher speeds. It also has made improvements on the patented RAKE function to minimize drag (only applied on the rotors). We will periodically update this section with new helpful information about our roll damping systems.
As opposed to fin stabilizers, this roll damping system generates high lift forces starting at 3 knots. The RotorSwing is based around the Magnus effect. Most people are familiar with top-, and bottom spin effect driven balls in sports such as tennis and soccer. A rotating forward moving round or cylindrical object generates an upward or downward force. Water is 784 times denser than air, which makes it the most powerful roll damping system for lower cruising speeds on the market.
Since the Rotors are placed almost horizontally, all of its liftforces are being used to stabilize your yacht. This is another great benefit compared to other roll damping systems. The Rotors also don’t have to follow the so called hull envelope boundary since they are retractable. This has given us the flexibility to produce longer rotor arms to create even more lift-forces!
At Zero Speed mode
The latest and most complete invention from RotorSwing Holland 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 higher speeds!
At Cruise Speed mode
The ATCruiseSpeed mode of the Rotorswing stabilizer systems provides roll damping while cruising starting at 3 knots. This function is the default setting of this Rotorswing stabilizer while cruising in higher speed modes. The Rotor is positioned perpendicular to the hull while providing maximum lift forces. The improved adaptive electronics continuously calculate the best timing, rotation speed and direction for any given wave condition. If faster cruising speeds are required and possible, the Rotorswing Rotors automatically enables the RAKE function. This will limit the amount of unwanted drag forces while continuing to provide for great roll damping results.
