When a high-speed displacement ship is designed, it is the most interesting thing for designers to reduce her residual resistance, because it takes the large part of her total resistance. According to recent studies, it is known that the residual resistance consists of wave-making resistance, spray resistance and water head resistance. It is hence necessary to study how to reduce each resistance component. It is possible theoretically to make a hull form whose all components are minimized, however, the obtained hull form is hard to be realized. The study how to realize is carried out, then a practical form which has small spray at the bow is obtained. However, the form does not give small wave making resistance though it is possible theoretically to reduce wave making resistance. In this report, it is discussed how wave making resistance is reduced on the spray free condition. The result shows that diminishing bow spray and reducing wave making resistance are affected each other, and it is hence impossible to reduce both of them at the same time.
