Abstract

PURPOSE: To both reduce resistance of a ship and decrease its pitching and rolling motions, by selecting the proportion between submerged depth of a submerged body of the semisubmerged catamaran and its mean diameter to a specific value.
CONSTITUTION: A semisubmerged ship, in which a top structure 3 is supported to the upper portions of two submerged bodies 1 always positioned under the level of water and parallelly arranged to each other in the forward direction through struts 2, is constituted in such a manner that espacially the struts 2 are further extended rearward from the rear end of the submerged bodies 1 and parts 2' of the struts are still existent even near above propellers 5. Further the submerged body is formed into a shape such that the proportion f/D between submerged depth (f) of the submerged body and its mean diameter D is in a range of 0.7W1.2. In this way, a stream of water in the stern portion can be improved to eliminate a possible racing of the propeller further reduce pitching and rolling motions of the ship body.
