Abstract
An ocean wave energy converter (WEC) using one or more elongated light-weight low-cost surface floats, oriented and self-orienting parallel to oncoming wave fronts are mechanically linked to a motion stabilized or fixed frame or base through one or more power take-offs in such manner that multi-directional rotational and translational wave-induced forces and relative motion between the float(s) and base are efficiently captured. Some embodiments have at least one forward positioned float that moves upward and rearward on wave crests and downward and forward on ensuing wave troughs to capture a majority of both heave and surge wave energy components. Other embodiments also provide apparatus and means to totally submerge the floats during severe seas or adjust submerged depth and float mass to optimize performance.
