If twin rudders are used for improving steering and maneuvering, suitable rudder location may also provide gain in propulsive qualities; advantages seem more favorable for ships with flat and transom sterns; for medium propeller loadings, twin rudders in place of nozzle may avoid high cost of nozzle; noise and vibration would be lower than for single rudder; optimum rudder locations recommended.
