To calculate the critical line of deck wetness in regular oblique waves, the vertical displacement of ship side relative to wave surface z_r, is obtained considering vertical displacement of the ship side due to heave, pitch and roll. The dynamic swell-up due to heave, pitch, sway, roll and orbital motion of the wave is also taken into consideration. In the meantime, f_s, the relative elevation of water surface due to trim, sinkage and elevation of water surface generated by the ship running in still water is obtained experimentally from model tests. The critical point of wetness is defined as the case when z_r coincides with f-f_s, where f is the geometrical freeboard of the ship.
