Beginning February 2013 DMS Holland and  RotorSwing Marine opened a new sales/service office/showroom. The office is on the premises of Altena Yachting: situated in the centre of Holland and easy to reach both by water and by car: directly at the Maas River and the motorway A27.Altena Yachting provides maintenance, repair and renovation of ships: installation of the RotorSwing Magnus Effect stabilizers can be done under direct supervision in both new builds and in refits: a perfect combination. Our demonstration vessel TESSERA will be available upon appointment and the RotorSwing crew would love to show you the unbelievable capacities of the new stabilizer system.
