A marine energy hybrid includes a support structure locatable at or near the surface of a body of water and at least two of (a) a hubless upper carriage movable along an upper track of the support structure with at least one wind vane mounted at the upper carriage to induce motion of the upper carriage relative to the support structure by reaction with the wind stream, (b) a hubless lower carriage movable along a lower track of the support structure with at least one water vane mounted at the lower carriage to induce motion of the lower carriage relative to the support structure by reaction with the water current, and (c) at least one wave energy conversion device integral with the support structure and operable to generate electrical or mechanical power in response to wave motion of the body of water.
