Improved Zero Speed Roll Damping System
RotorSwing Holland offers test rides at the Boatshow in Lelystad (HISWA te water) from 4-8 September. We would love to prove to you the power of this improved roll damping system while at anchor and cruising.
Assembly and Testing RotorSwing Systems
July 26th, 2019
At RotorSwing Holland, we fully assemble and test every roll damping system before shipping it to our yacht owners. Our engineers constantly strive to improve the roll damping system that is based around the Magnus effect.
Yacht stabilization is far from being a novelty, but this Roll damping system from RotorSwing Holland is superb for yacht stabilization while cruising, at full speed and while at anchor (Zero Speed).
The demand for our Zero Speed version, also called “atFullSpeed”, is increasing mainly because it now also allows for cruising speeds from 0 knots to 25 knots.
RotorSwing’s new and larger facilities offer space for assembly and testing
Our Special Lady…
June 10th, 2019
A nice birdseyeview of our Fairline 55’ “Lady G” moored in Guernsey at the fuel dock being prepared for sea trial demonstrations.
The RotorSwing 140 Multi installed in the vessel is one of the first systems where we were able to test the combined functionality of this unique roll damping system at various speeds. Principally the Magnus effect is mainly employed with displacement vessels, our Patented RAKE functionality however, enables the use up to 25 knots.
The easy to install, fully electric drive system combines a silent and smooth operation with optimum roll damping characteristics AtCruiseSpeed (3 to 25 knots) and AtZeroSpeed (0 to 3 knots). Our Magnus Rotor system on Lady G has achieved 85% roll reduction AtZeroSpeed and 91% roll reduction AtCruiseSpeed.
Lady G is available for demonstrations in the Channel Islands, please contact RotorSwing UK at: +44 (0) 1481 726 267 or email email@example.com.

RotorSwing 140 Multi Zero Speed for MY iRock, Baglietto 34m (114 feet)
May 20th, 2019
May 2019 was a successful month for RotorSwing. Besides our standard roll damping systems for motor yachts around 15 meters, we supplied our first 4 rotor ZeroSpeed system for this Italian 34 meter (112 feet) yacht. The very capable shipyard in Varazze (Italy) installed the aluminum welding bushings and RotorSwing teamed up with a crew of 4 men to do the installation. This pleasant cooperation with the ship yard resulted in a quick installation, directly followed by a sea-trial. Both the yacht owner and RotorSwing crew were astonished about the damping results and the performance of this 4 ZeroSpeed roll damping system.
The season still has to arrive, but the first experiences in the Monaco Yacht Basin were very positive. All adjustment parameters are accessible on the display which has been installed on the bridge. One of the main electronic control cabinets also has a built-in display for system operation from the engineers control room. The 4 zero speed roll damping rotors work in perfect sync with each other through our improved electronics. Currently, RotorSwing Marine is also negotiating an exiting possible deal for a 6 Rotor system! Stay tuned…

Our 43’ fast Colvic RotorSwing test vessel has recently been used intensively to test and optimize the RotorSwing roll damping equipment. Important issues as minimizing drag and perfecting roll damping characteristics were already completed and our engineers were ready for a new challenge.
We equipped our test vessel with our latest ZeroSpeed stabilizer equipment using the newly designed and advanced underwater drive units with carbon rotors. The challenge was to perfect the damping of the roll motions at anchor or adrift on board of vessels with a short roll period and to avoid jerky motions so common for the cause of seasickness.
But…..how do you test this when there are no waves to make the ship roll? And you are extremely curious after the results of your work? Just use the same engineers! With nearly 100 kg Rien used all his weight to make the ship “forced roll” with a remarkable result of 2 x 7 degrees.
After a few excitation rolls we switched the RotorSwing ZeroSpeed to ACTION. The residue roll was only 2 x 1 degrees. A remarkable result of 86 % roll reduction.
Our engineers found their tests succeeded all expectations and with roll reductions of 86 % a remarkable result in ZeroSpeed roll damping. A unique combination of body and brain exercises.

“I’m amazed how good it works!”
February 25th, 2019
“The technology is clearly complicated and it amazes me how good it works. During the 10 days that I have used it the underway seems to function without error other than some issue with sensitivity which caused shutdown on two occasions but Phillip says it just needs some adjustment. I think this is just a programming issue and not a real problem.
The stabilizing effect is very good to excellent at all speeds from the slowest (4 knot) to the highest speed the boat will travel (19 – 20 knot). There does not seem to be any effect on the speed of the boat. Amazing how little room it has taken up in the engine compartment and how quietly it operates.
Zero speed stabilizing effect is also very good and operates quietly other than some vibration that can be felt from time to time.”
RotorSwing is less vulnerable than Fin stabilizers
Rare Feadship classic Caravelle upgraded with RotorSwing’s next generation stabilisation technology
February 14th, 2019 The Feadship Caravelle’s year-long refit included the complete stripping and rebuilding of the engine room and installation of four RotorSwing at-anchor stabilisers.
The addition of RotorSwing’s retractable and electrically driven Magnus Rotor Stabilisation system on this Feadship, this timeless beauty of the sixties is the perfect combination of classic style with next generation technology. Now equipped with high performance stability control AtZeroSpeed & AtCruiseSpeed, the new owner of this restored iconic yacht can fully enjoy her style and comfort.

RotorSwing Holland purchased a fast GRP test ship
January 19th, 2019 RotorSwing Holland purchased a fast GRP vessel to enable the optimization of all the parameters involved in the AtZeroSpeed equipment. Having invested heavily in CFD (Computational Fluid Dynamics), our goal is to compare reality with results from this highly advanced computer program. Beginning 2019, the JULIA, a Colvic 43′ planing vessel will be ready to fulfill its duty as a test vessel. The latest version of our ZeroSpeed equipment has been installed and she will be soon ready to go to sea.
RotorSwing Holland moves to larger premises!
Beginning 2019, RotorSwing Holland will be moving from Beek to Nuth, Holland. As a result of a very successful 2018 our manufacturing facility and offices in Beek, started to become too crowded. We decided to move to Nuth, next to the “home port” of the Quantum Group.
This large facility offers sufficient production and assembly space for further growth in the near future.
RotorSwing Holland got published in PassageMaker Magazine
October 12th, 2018 Dag Pike, from PassageMaker, was onboard the Altena 50 Pilothouse owned by the owner of RotorSwing Holland. This 5 page article talks highly about the RotorSwing ZeroSPeed stabilizer. During the day of testing, the weather didn’t allow for impressive waves. Inventor and owner Theo Koop was able to impress Dag Pike by switching the gyro signal in order to set the system to the forced roll function. This integrated forced roll system is used for test scenarios to make the vessel roll in an extreme measure within a few seconds.
