Abstract
The invention is directed to an apparatus for mitigating the load impact on a surface watercraft and passengers therein, during high speed travel. The hull includes a damping cavity for mitigating the load impact on the surface watercraft. The damping cavity is positioned on a dry portion of an undersurface of the hull between a forward end and an aft end of the hull. The damping cavity includes a porous plate on the undersurface, and a deck plate within the hull body. The deck plate and the porous plate are separated by a gap, and an inflatable bladder may be positioned in the gap between the plates.
