A float structure for a WEC is designed to have a tapered underside to reduce the impact due to wave slam and bending moments while providing little reduction in the surface area responding to the wave surface in order to maintain the beneficial power generating capability of a 'flat' float. The underside of the float presents an inverted wedge section to decrease loads associated with wave slamming. The float may have a generally toroidal or elliptical configuration at and about the 'still' water line with the generally submerged underside of the float having a cross section shaped to have one or more inverted triangular sections extending between the outer perimeter of the float and its center to reduce impact loading due to wave slamming while maintaining power producing capability.
