한국 어선선형의 저항성능에 관한 기초연구

초록

The representative hull forms in Korea and Japan are selected and compared to estimate the resistance performance for the Korean fishing boat. The Korean fishing boat has different kind of fishery and custom against the Japanese fishing boat. Those things reflect the parameters that the Korean fishing boat has shorter Load Water Line, Draft and wider Breath than the Japanese fishing boat with the same displacement. As a preceding study, however, even though the parameters of the each hull form are similar, the resistance performance of the Korean fishing boat is worse than the Japanese fishing boat. Therefore the characteristics which are the gradient of chine line, the keel shape and the stern length should be revised. The Korean fishing boat is revised by the Japanese fishing boat to confirm the partial characteristic differences between the hull forms with the same displacement. The resistance performance of the revised hull forms is confirmed by INHAWAVE. This study will be used to improve the resistance performance and to develop into a practical hull form of the Korean fishing boat for preliminary data.
