A wave-powered device, including a first barge; a second barge; a third barge; a first coupling mechanism coupled between the first and the second barges to enable the first and second barges to move relative to one another; and a second coupling mechanism coupled between the second and third barges to enable the second and third barges to move relative to one another, the first barge including first and second preexisting barges of predetermined size and shape selected from a group of preexisting barges, the first and second preexisting barges being coupled together to form and act as a single, unitary barge, and the first and second preexisting barges being structured and arranged to optimize predetermined wave conditions. Also, a compressed air motion attenuator assembly for use in a wave-powered device, comprising a cylindrical housing; end plugs positioned at opposite ends of the housing; and a piston and shaft assembly positioned and moveable within the housing, with the shaft extending out from the housing, the housing including breathing slots extending through the housing and having a predetermined length along the housing, the housing forming an air trap at each of the two ends of the housing, the slots and air traps being structured and arranged such that air is compressed when the piston travels beyond the slots at either end of the housing, and the air traps being a predetermined size based on the compressibility of the entrapped air. |
