Cross Over Rudder New Rudder design with optimised Fairing Hub Cap & Rudder Bulb The new generation of efficient merchant vessel requires high standards of manoeuvring and propulsion efficiency. The new Cross Over Rudder design unites Becker Marine Systems’ expertise in rudder design and new propulsion efficiency technologies by introducing a new type of rudder featuring a rudder bulb and fairing cap. Main benefits of the new Cross Over Rudder: • The new FEHC Flow Efficient Hub Cap • An optimised rudder bulb with no loss of manoeuvrability • Fuel savings of up to 7% due to efficient rudder design • Improved course keeping • No propeller hub cavitation • Available for newbuildings and retrofits • Designed for feeder vessels and ferries • Optional trailing edge flap available Cross Over Rudder model for performance test at Korean model test facility.

Cross Over Rudder CFD simulation of energy losses in the water flow without rudder bulb. Same CFD simulation with rudder bulb showing reduced energy losses. Using the experience of aft ship optimisation with energy-saving devices and flow-optimised rudders, Becker is introducing the Cross Over Rudder as an improved propeller/rudder solution, including a new fairing hub cap (Flow Efficient Hub Cap or FEHC) and a new rudder bulb design with no loss of manoeuvrability. Extensive CFD studies and model tests have improved the performance of this type of rudder by 150% over conventional rudders....
