This paper presents a study for the improvement of hu11 form design considering the effects of frame-shape. Based on the Separability Principle of Ship Form, a philosophy by which the frame-shape of aft-part are divided into two parts to make solving the problem easy, one is the part of main hull and the other is the part of skeg, was contrived. According to this philosophy, new formula for estimating viscous resistance and propulsive coefficient, and new method of designing C_p curve of aft-hull form, have been developed after analyzing the results of model experiments on various ship forms. A comparison of the calculated K, 1-wr and 1-t values with those by experiments show a good agreement in a wide range of ship type. Adequate shape of C_p curve without fear of separation of water flow even in case of large B/d ship form, is obtained by this method.
