Abstract
PURPOSE: To improve sea worthiness while reducing construction cost without lowering propulsive performance, by providing this ship with sufficient restoring property even in the rough sea.
CONSTITUTION: This catamaran consists of a pair of left and right single drum hulls 2 floating on the surface of water 1 and a connecting portion material 3 for connectingt hese single drum hulls 2 at upper portions than the surface of water 1, each single drum holl 2 is equipped with a type of a ship shaped by smoothly connecting the midship cross section by a plane bottom 2a, perpendicular side-wall portions 2b and curves 2c, and each section of a first half portion and a latter half portion is shaped in a swelling form in the lower portion that width under the surface of water is is larger than width at the line of the surface of water. That is, each single dunm hull 2 is shaped to ensure that its midship cross section coefficient cm is smaller than 1 and its vertical post form coefficient Cvp is larger than 1. This method can obtain the catamaran that can effectively display the desirable target.
