DMS MagnusMaster

For low-speed cruising and semi-displacement yachts up to 30 metres

Print

You cannot compare the MagnusMaster with other conventional stabilisation systems due to its technical innovation and better results. This latest generation of rotor stabilisers provides roll damping at low speeds of 3 to 12 knots on yachts up to 30 metres. At speeds above 12 knots, the Magnus effect no longer increases and therefore the DMS MagnusMaster automatically retracts.

When retracted, the rotors remain largely within the turbulent boundary layer of the vessel, meaning resistance is negligible.

It is a work of high-quality technology based on a universally acknowledged law of nature: the Magnus effect, that works in both liquid and air, was discovered and documented by Heinrich Magnus. DMS Holland has been able to optimise this effect by developing and applying advanced new techniques.

DMS Holland has been able to optimise this effect by developing and applying advanced new techniques. To guarantee durability and continuity, the system uses electronic components from the well-known German brand Lenze, including electric motors, displays, drives and servo motors.

Amazing video footage from the 24 metre MV Astra in the South West Pacific Ocean showing how well the DMS MagnusMaster stabilisers operate

MV Astra was designed and built for deep sea rescue operations in the harsh conditions of Sweden and extreme Northern Europe.

She is currently on a 'Reverse' Southern Capes Circumnavigation (which includes Cape Horn and the Cape of Good Hope). The owner/captain recently sent us this incredible video of DMS MagnusMaster in operation in the South West Pacific Ocean.

MV Astra is of exceptional steel construction built with the highest icebreaker rating for extreme operations and is equipped with a four rotor MagnusMaster stabilisation system. This is one seriously tough vessel currently undergoing a seriously tough challenge.

Testimonials

Mark Bakker

Director Aquanaut

“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.”

“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.”
