Abstract

PURPOSE: To stabilize the pitch of a semi-submerged dual hull ship by providing a stern stationary fin.
CONSTITUTION: Front and rear control fins 5, 7 are provided at the stern sides of the respective lower hulls 2 of a semi-submerged dual hull ship formed by connecting one upper hull 1 to two lower hulls 2 by strats 3, 4 with stern stationary fin mounted at the top of a properller 8 and rudder 9 far from the centroid position. Thus, since the distance l from the centroid of the stern stationary fin 6 becomes large, it can provide large stability moments Ms so as to improve the stability against the external turbulence at high speed of the ship.
