Following the first report in which the characteristics of transverse porpoising of a drifting planing craft in calm water were experimentally shown and the mechanism of transverse porpoising was clarified, a computer program is developed to simulate the transverse porpoising. It is confirmed that the simulated results are in fairly good agreement with experimental ones. Using the simulation program, the effects of location of center of gravity on the transverse porpoising are investigated. The results suggest that reduction of transverse porpoising can be achieved by moving the center of gravity forward or upward. This fact is also confirmed by experiments. Although the transverse porpoising is a coupling motion among roll, pitch and heave motion, it is experimentally and numerically confirmed that only roll and heave motions play important roles in occurrence of the transverse porpoising.
