1. A wave energy converter comprising:
a nacelle having a starboard side and a port side, the nacelle housing a power take-off;
at least one buoyancy member coupled to the nacelle;
a ballast tank coupled to the nacelle, such that the ballast tank, the at least one buoyancy member, and the nacelle, together form a first body, wherein the first body is coupled to the power take-off; and
a float and a drive arm forming a second body, wherein the second body is rotatably coupled to the first body about a coupling axis, wherein the second body is coupled to the power take-off; and
wherein the second body is configured to rotate relative to the first body about the coupling axis within a radial span bounded by a proximal end of the float and a radially distal end of the float.
