Abstract

A wave energy converter includes a surface float including a non-axisymmetric profile, a reaction plate configured to be submerged below a water surface, and more than one flexible tether, each mechanically coupled to both the surface float and the reaction plate, the reaction plate having a moment of inertia in pitch and roll greater than a moment of inertia in pitch and roll of the surface float.
