PROBLEM TO BE SOLVED: To provide a sufficient antirolling effect against the rolling of a multihull. SOLUTION: A pair of side hulls 12, 13 disposed on left and right sides of a main hull 11 at the center and forming a three-hull ship as the multihull are so diagonally disposed that their bottom sides are extended outward. The side hulls are formed in a chevron shape when viewed in the longitudinal direction. A bilge keel 15 is so attached to the bottom part of each of the side hulls 12, 13 as to project diagonally. Consequently, a damping force is generated during the rolling also on the side hulls 12, 13. COPYRIGHT: (C)2009,JPO&INPIT
