Abstract: A wave-powered device having enhanced motion. The device including first, second, and third barges, with the second barge having a first reservoir and a second reservoir. The first and second reservoirs being coupled by a first passageway to permit a first fluid to selectively and passively move between the first and second reservoirs in a predetermined manner to increase the pitching moment of the second barge while the second barge pitches while floating over waves. A first coupling mechanism is coupled between the first and second barges to enable the first and second barges to move relative to one another, and a second coupling mechanism is coupled between the second and third barges to enable the second and third barges to move relative to one another.
