A 2D+t method in combination with a numerical potential flow solver is used to simulate steady drift and yaw motions of a planing hull. A special technique is applied to model the effect of spray reattaching to the side wall and its influence on the hull forces at different forward speeds, trim angles, drift angles and heel angles is investigated. The resulting force and moment components
with and without the reattachment model are compared to published experimental data. The agreement of side forces, roll and yaw moments is considerably enhanced by the reattachment model in certain conditions and generally favourable. There are some deviations in the predicted vertical lift force at high drift angles which are assumed to be caused by a low-pressure region around the keel in the potential flow solution.
