Abstract
Aiming at the simplification of the process in working-up the shell plating of a vessel, the authors investigate the possibility in applying the developable surface-especially the tangent surface-to the forward and after parts of the shell plating, and sacceed in obtaining a general method to get proper lines of a simplified hull form satisfying requirements in W. L. and prismatic curves for the loaded condition. Such a new simplified hull form is expected not only to save time, labour and cost in shipbuildig but also to keep excellent characters in resistance, propulsion and seaworthyness. An example of such a simplfied hull form and the results of towing experiments at the model basin are shown in detail.
