Abstract
The forward deck of a swath or catamaran type vessel is constructed largely of a sieve-type material, such as honeycomb-type deck grating. Should the foredeck of the vessel, which is normally suspended above the water line become submerged by plowing into a wave, or otherwise inundated by large masses of green water which would otherwise tend to weight the bow of the vessel down, the above deck water will simply drain through the sieve-type material and permit the inherent flotation of the pontoons and hull of the vessel to promptly raise the bow to relative horizontal position.
