Recently the theoretical study of the motions of catamaran ships has proved to be highly encouraging with the aid of the strip method. And then the two dimensional hydrodynamical forces of catamaran ships become very important for calculating ship motions. Ohkusu has developed the very effective method to calculate hydrodynamical forces and S. Wang and Wahab calculated those of heaving circular cylinder which are good agreement with experimental results. But these papers dealt with only Lewis form sections. This paper presents the theoretical results by making use of the source distribution method and experimental results of so called waveless ship forms as one of arbitrary ship sections, when these sections heave, sway and roll. The two dimensional hydrodynamic forces calculated are in good coincidence with experimental ones.
