DMS AntiRoll

For low-speed cruising superyachts over 30 metres


This innovative roll damping system has been developed by DMS Holland and perfected together with renowned partners such as Marin, TNO and TU Delft.

Thanks to its unique dual-axis fins, which rotate while underway and make a flapping motion when the yacht is stationary (zero speed), DMS AntiRoll stabilises both underway and when the yacht is at anchor, without compromising on performance in either situation. The concept and operation of this ingenious system takes its inspiration from the fins of the blue whale. Due to the patent obtained for this way of roll damping, the system cannot and must not be replicated by others.


In addition, the flapping movement of the fins generates a much greater lifting effect than fins that only rotate when the ship is stationary. Furthermore, the fins can be retracted or partially folded back into the hull, making the system also suitable for sailing yachts. AntiRoll uses a smart hybrid drive, meaning the system requires relatively little power. DMS has also kept noise of the system during operation to a minimum.

Model and drag tests and expert evaluation have confirmed that the AntiRoll system delivers enhanced performance in both stabilisation and resistance through the water.

“Why do I usually recommend people to choose a MagnusMaster rotor system? The most important argument is that the rotors are retractable. On the one hand, that’s too bad because I had a good business in replacing fins. I obviously lost that. But the customers are grateful that I accept that. Another important argument is that it takes up relatively little space on board. And that it has an electric drive. That makes installation also possible on many refit boats. One other benefit that is more for the future, for boats that are being built now, is that it is a CAN bus system meaning we are also able to connect to the Raymarine screens we install. This enables you to then completely monitor the MagnusMaster system.”

“I have already experienced a great deal of choppy water and waves with De Zwarte Ruiter. 2 weeks ago, during a weekend in Rotterdam, it was the Steam Power Event in Dordrecht and as a result, it was very busy on the water with speed boats, water taxis to / from Rotterdam and very choppy water. De Zwarte Ruiter was pretty keen to roll but she just couldn’t. It may well have cost money, but it’s worth it. My wife Cobie and I are of course very very happy with it. As I said from the beginning, it’s just like sailing on smooth tarmac.”

owner MY Blue Angel

“We then turned the stabilizers on and it was just incredible what I experienced. The boat just remained steady and really didn’t roll, not even with the waves. I couldn’t believe it at times. I honestly even sent Patrick a message in the evening; this is not normal, it is beyond our expectation.”

“A big advantage of the system is that it is a maintenance-free system, there is no need for lubrication and so there a service is not required. The system is certainly simple to operate, it is easy for the customer to read-out and monitor. User friendly. It is a CAN-bus system which, because it has NMEA 2000, can also be read-out on vessels’ big screen.”


Mr Per Johanssons

owner MV Astra

“One of the major reasons among others to install the DMS system is that they have different lengths of hull bushings that can be installed on this type of vessel. Some yachts need small bushings. The ones that we have used are over 500 mm long and they were readily available. When we came to the point of making business they were already on the shelf so to say. Very fast, very efficient, very good people to work with.”
