<P>PROBLEM TO BE SOLVED: To provide an oscillation reducing device capable of reducing pitching of a high-speed catamaran, and capable of improving ride quality and fuel economy by reducing sailing resistance even though the oscillation reducing device is provided. <P>SOLUTION: An attitude control device is provided in a tunnel-like part 4 between stern parts 5 of a hull 3 at both sides of the catamaran 1 so as to drive with oscillation control in such a state that a hydrofoil wing 6 is submerged for pitching control, and arranged at the center part of the catamaran 1 or the center of gravity. An elevation angle of the hydrofoil wing 6 of the stern part 5 is reduced by addition/substraction control so as to reduce a pitching angle with respect to pitching, so that sailing can be performed with the minimum sailing resistance according to the state of waves. <P>COPYRIGHT: (C)2012,JPO&INPIT |
