Abstract

A hull form improvement method is presented using Genetic Algorithm in conjunction with Rankine source method based on a wave resistance theory for modified hull. By means of the present method, improvement of fore ship form is introduced for Series 60 (Cb =0.6) hull. As a result, the wave resistance is reduced about 25% at Fn=0.3 by modifying the original form to bulb-like bow shape. We found that GA improves the estimation accuracy of the optimum hull form.
