A small saury fishing vessel (19GT-type) is newly developed and evaluated the total performance in order to increase profits and to attract the younger generation of fishermen. On the basis of inquiring surveys to fisheries unions, ship-owners and shipbuilders, problems and needs of saury fishing vessels are analyzed. Then, the performance of conventional fishing vessels is evaluated through model resistance tests in a circulating water channel. The hull form design for the fore-body is improved by the use of wave-making resistance theory. The aft-body is improved by the use of the Eulerian scheme with the Lagrangian particles. The general arrangement of the hull form improved vessel is developed to upgrade the habitability and fishing performance. The newly developed and advanced small saury fishing vessel can reduce the fuel consumption by half compared to the conventional vessels. An actual 19 GT saury fishing vessel, constructed based on the results of this study by using the present design method, demonstrates the superiority of performance.
