    Need someone to kindly help me to calculate turning moment of a TWIN-SCREW motor-ship with centre-line SINGLE rudder.
    Conditions are:
    Both engines ahead at same RPM.
    Ship's speed = 10 knots.
    Rudder angle = 35°.
    Rudder type = Simple (rudder post on AP).
    Rudder dims = 4,600 (H) x 3,850 (L) mm.
    Distance of centre of pressure from fwd edge of rudder = 1,430 mm (as calculated by Joessel's formula).
    Distance of ship's G from AP = 88 m.
    Many thanks for help!
