The Yachting division of Van der Velden Marine Systems, a member of the Holland Yachting Group, will exhibit at the Monaco Yacht Show (21-24 September 2011). Highlights of its presentation will include the green Barke rudder and the Van der Velden Commander steering gear. Van der Velden can be found in the Darse Nord Air Conditioned Tent at stand number QD71.
The Barke rudder from Van der Velden Marine Systems is renowned for its excellent manoeuvrability and high-lift. A less well-known quality of this specific rudder type is the fuel savings its offers compared to conventional rudders.
When a yacht is underway the autopilot corrects course deviations by adjusting the rudder angle. With a conventional rudder the complete blade will move and turn the vessel in an exaggerated large angle to port or starboard, creating the familiar zigzag course pattern. In contrast, Barke high-lift rudders are fitted with a sophisticated flap-linkage mechanism. Rather than moving the complete rudder blade the small flap moves most, and course corrections by the autopilot dramatically reduce the angle of movement and subsequent zigzag pattern. Turning circles are also much smaller with the Van der Velden BARKE® flap type rudders in comparison with the conventional rudders. The overall result is a reduction in travel distance and less fuel consumption.
