A DEVELOPMENT OF A SMALL TRIMARAN LEISURE BOAT

초록

A 12 m long 4.99 Ton Class Trimaran is now under development at the Center for Transportation System of the Yellow Sea (CTYS) before deployed as a pleasure fishing boat along the west coast of Korean peninsula. The boats will be made of fiber reinforced plastics and equipped with a 360 hp diesel engine and a water jet propulsion system to propel the ship to reach maximum speed of 25knots after fully loaded. Model tests for hull forms development of the Trimaran have been done at the towing tank of the Inha University. The influence of the spacing between main hull and outriggers and the longitudinal location of the out riggers have been carefully examined to find the optimal size and locations of the outriggers to improve both the motion and resistance characteristics, and the results are reported in the present paper.
