DMC rudder retrofit aids manoeuvring

DMC retrofitted a Van der Velden BARKE high lift flap rudder, including bulb, on Coastal Transportation’s 73m short-sea vessel, Coastal Standard. BARKE rudders incorporate a flap design with a more than 100° flap angle to delivers maximum manoeuvrability and course-keeping. The enclosed linkage system of the BARKE rudder reduces noise levels, provides overload protection and eliminates the entry risk of floating objects, sand and ice.

“The captain gave us a very positive report regarding the manoeuvring characteristics. The BARKE rudder requires less input to keep the vessel on a straight course. Also, it is significantly quieter in the wheelhouse when running at full speed,” said John Fisker-Andersen, port engineer at Alaska, US-based Coastal Transportation.

Leo van Zon, DMC area sales manager, added: “During course keeping this slim profile rudder ensures minimal resistance while the progressively operating flap delivers unbeatable performance when manoeuvring.”

The rudder was fitted in the spring of 2019, the vessel completed her sea trials in June.

Since their introduction in 1984, DMC has delivered nearly 1,000 Van der Velden BARKE rudders to vessels, ranging from coasters, naval ships and ferries to tugs, fishing boats and superyachts.
