This paper deals with the problem of the behaviour of a ship in restricted waters with special regard to underkeel clearance. The main factors affecting the keel clearance are squat, heaving and pitching motions, the occurrence of a heeling angle due to windpressure and ruddermovements and the rolling motion. Distinction will be made for canals, shallow water of finite width and shallow water of infinite width. It is emphasised that the efforts are mainly concentrated on the several calculation procedures which exist for squat and the difficulties involved in practical applications.
With respect to the ship motions in shallow water waves a simple calculation method according to the conventional strip theory is presented and discussed.
