ABSTRACT:
A vessel includes two or more barge form hulls disposed apart vertically one above the other and multiple spaced connecting structural members rigidly inter-connecting the hulls with a gap therebetween. The upper hull provides the necessary buoyancy to support the vessel with the other hull or hulls flooded with sea water and/or other liquids. Waves acting on the vessel may cause a water flow in the space between the hulls and the wave energy may be at least partially dissipated by the action of the water flow between the hulls and on the connecting members.
