The HD rudders provide an excellent manoeuvring performance, which is proven in practice and in the most stringent towing-tank trials. These high-efficiency rudders can be used with or without a nozzle. They have an asymmetrical profile and are always applied in a pair. The HD rudders have been especially developed for inland vessels in combination with a 2, 4 or 6 rudder propulsion set-up.

The HD rudders have asymmetric rudder angles up to 80°, providing optimal slipstream guidance. With these rudder you are assured of an excellent manoeuvring performance, also with low velocity. They have a maintenance-friendly design and a long lifespan.
