A Study on the Estimation Method of EHP of Small Fishing Boats Having Chine Line and Optimization Technique of Hull Form Parameters Having Low Resistance

Chine Line이 있는 소형어선의 유효마력 추정법 및 최소저항을 갖는 선형 요소들의 최적화에 관한 연구

From the results of model tests, statistical regression analysis for EHP estimation based on hull form parameters is adopted in this study. From this result, the method for estimation of EHP and optimization of hull form parameters at the initial design stage of fishing boats is developed. This method is applied to two standard fishing boats with chine lines. The EHP s are estimated and compared to experimental results. From the optimization of four principal hull form parameters of these fishing boats, approximately 19% of resistance reduction at the design speed is achieved and thus certifies that this method can be used efficiently for the initial design of hull forms of fishing boats.
