Abstract

PURPOSE: To improve the integrated performance, that is, to reduce the power required for a ship and decrease its rolling and pitching motion or the like, by constituting the proportion between sinking depth of a submerged body and its mean diameter and between height and width of the submerged body in a range of prescribed value.
CONSTITUTION: On a submerged body 1 arranged in such a manner as to be in parallel to the longitudinal direction of a ship, a plate-shaped strut 2 is vertically provided and arranged so as to be extended almost throughout overall length of the submerged body 1. The proportion f/D between depth (f) of the submerged body 1 and its mean diameter D is determined to 0.7W1.2, in this way, total resistance and wave drag of the ship can be lowered at its sailing, while a flatness of the submerged body 1, that is, the ratio HL/BL of its height and width is determined to 0.6W0.8, in this way, pitching and rolling motions of the ship in waves can be suppressed to ensure a safety navigation.
