In this paper the author considered the mutual interference of ship hull and propeller in shallow water and restricted water, in particular, from the standpoint of wave-making.
The main problems treated are as follows.
(1) Expression for the wave resistance of a system, consisting of ship hull and sink propeller, in shallow water and restricted water is obtained.
(2) The cause of wave resistance augumentation by the suction of sink propeller is clarified from the viewpoint of component wave, with special reference to shallow water effect and restricted water effect.
(3) The wave resistance augumentation is divided into two components, and explained substantially.
(4) The wave wake at the position of sink propeller in shallow water and restricted water is considered.
(5) The variation of propeller performance in shallow water and restricted water is shown in the variation of thrust coefficient and advance constant.
