Abstract

One of tuna longliners which have excellent operational record at the tropical Pacifical Ocean was selected as a parent hull form for the development of a new ship which could be operate at the high latitude northern Pacific Ocean. The parent hull was modified to adapt operational and enviromental condition of such a weather and sea states. This modification was carried out based on design experiences and model test results in towing tank. In this report modification techniques applied to the hull form design of a tuna longliner are summarized. The powering performance of the developed hull form is evaluated to show 19%, decrease of resistance campared with the parent hull form.
