An enhanced rudder force prediction model is described in which the rudder and propeller are treated as a combination and for which an extensive experimental and theoretical parametric database has been established. The database contains information for all four quadrants of ship operation, at low speed and the effect of the hull on rudder-propeller performance. The performance of the enhanced rudder model has been tested in a ship simulator and its results compared with those for a more traditional model of rudder -propeller interaction. The results of the tests indicate that the use of the enhanced rudder model can lead to significant changes in the predicted side and axial forces and that the incorporation of such a model in manoeuvring simulations should lead to improvements in the representation of rudder-propeller interaction effects.
