The Relation between the Sectional Form of the Shio and the Wave Resistance

船體斷面形狀(船體斷面形狀)과 조파저항(造波抵抗)과의 관계(關係)

This paper was intended to compare the relationship between sectional form of ships and wave making resistance by calculating the resistance value practically rather than theoretically. As the sectional form of ships, four types of quadratic ship forms was introduced and he wave making resistance was calculated by the Slender Ship Theory. The main result obtained in this paper is the following. The relationship between the displacement distribution of draught direction in the given sectional form of ships and the resistance value was shown. It was supposed that the resistance value will decrease with the increase of the displacement distribution of draught direction and it was proved by the numerical value.
