NOVELTY - The structure (10) has a forward and after barges (15) which are movably connected to central barge (12) to allow for articulated motion. An inertial damper plate (17) is connected to lower portion of central barge to provide displacement stability to central barge. An inertial damper is connected to central barge to produce pendular motion of center barge. An energy conversion device is operatively connected to barges so as to collect and convert energy from wave motion impacting and displacing the forward barge and after barge relative to central barge.    USE - Structure for converting wave energy used in power generation system positioned in seawater in path of oncoming waves.    ADVANTAGE - The energy is extracted efficiently from a wide variety of wavelengths of ocean waves. A wave motor can easily be scaled up to provide a large amount of power cheaply and that is simple enough to require a low level of maintenance. The floating structures are designed to minimize reflected, transmitted, and self-generated waves thereby maximizing the power absorbed from ocean waves. The floating structures employ the use of controlled mass, moment of inertia, and the geometrical shape of the hull to match the structure response to the spectrum of the incident waves, thereby maximizing power extraction efficiency. The floating structures employ light weight structure for all elements that are not needed for holding ballast, machinery, or for sustaining high operating loads, thereby reducing capital cost. The power extraction device incorporates a control element that allows the power extraction impedance to be varied for maximum power extraction efficiency, thereby allowing maximum efficiency of power generation over short intervals of time.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for system for collecting and converting wave energy.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the system for converting wave energy.
