It has been becoming a great important problem to predict the hydrodynamic forces and ship motions in water of finite depth, because of increasing dimensions of ships. The studies of ship motions in water of finite depth, however, have been limited comparing with those in water of infinite depth. It is therefore desired that the correlation works between theoretical and experimental investigation should be performed and extended to oblique waves on water depths smaller than twice the draft of the ship. In this paper, author measures the amplitudes of motions of tanker ship model with various heading angles in waves at a shallow water tank. The experimental results are compared with the results of theoretical calculation obtained by so-called "New Strip Method". It becomes clear from the above comparisons that the theoretical calculations according to New Strip Method agree approximately with the experimental results in oblique waves, and especially the theoretical and the experimental results with zero-advancing speed agree very well in beam sea condition.
