한국 고속 소형 연안어선의 저항성능 연구

초록

The Korean fishing boats have had appropriate hull forms for the safety, stability and the convenience of fishing. However, the Korean fishermen are recently concerned about the resistance performance and the speed of the Korean fishing boats, because the prices of fuel oil are skyrocketing, and the exhausting of fish resources and the demand of high speed fishing boats are increased. Therefore, the necessity of the study on the improvement of resistance performance for the Korean small coastal fishing boat is gradually increased. This study is concerned with the development of the semi-planing hull form of 25 knots high-speed small fishing boat. From the modification of the hull form parameters for the Korean fishing boat, the variation of the resistance performances is evaluated. From the modification of the local characteristics of the hull form of the Korean fishing boat, the variation of the resistance performances is also evaluated. Also, the modified hull forms will be estimated for the resistance performance by using a computational method and ship model tests in towing tank.
