Abstract
PURPOSE: To automatically secure the longitudinal stability of the hull by a method wherein slanted fin-stabilizers skewly crossing the designed draft are provided at the stem and stern between the lower hulls of the semisubmerged catamaran, in a symmterical manner regarding the center plane of the hull.
CONSTITUTION: An upper hull body 3 above the water surface is provided on a pair of right and left lower underwater hulls 1 through support columns 2. Between the lower hulls 1, slanted fin-stabilizers 6 are provided at the portions near the stem and near the stern in such a manner that they are symmetric with respect to the center plane of the hull and they cross the designed draft 5p skewly. The fin- stabilizers 6 increase the longitudinal stability of the catamaran and keep small the change in the angle of trim at an arbitrary intermediate speed below the designed speed, even through the fins are fixed ones.
