The Effects of the Gravity Center on the Hydrodynamic Behavior of a Wave Rider Buoy

A numerical procedure was employed to investigate the dynamic performance of a wave rider buoy. The linear matrix form has been derived to describe the equations of the motion. The hydrostatic and hydrodynamic coefficients of the wave rider buoy have been computed. Three cases of the buoy center of gravity were considered. The numerical results showed that, the stability of the buoy was increased by lowering the buoy center of gravity, but the quality of the dynamic response should be reduced, which is a disadvantage regarding the mission of the buoy.
