An alternating Open Chamber Cavity for employing a very useful safe and controllable new lifting plus lubricating hydrodynamic force for effectively improving marine transportation in a seaway, I named SAFELY CONTROLLED, AUTOMATED WATER DISSECTED LUBRICATION AND LIFT FORCE, has been discovered and innovated for use by myself; and I have also invented the automated mechanism I named “FLEXIBLE POWER-FINS”, for controlling the safe exploitation of this beneficial natural phenomenon, as well as innovated a way to significantly improve the turning capabilities of a watercraft in motion.

The invention concerns a vessel for floating in a body of water, comprising a hull having an aft hull section and an aft body arranged at a distance from the aft hull section, thereby forming a passage into which water can flow. The aft body and the aft hull section are designed to minimize the vessel's stern wave during forward movements.

A boat pontoon having a concave V-shape on a bottom portion thereof, generally straight vertical sides, a flat top panel member, and a removable and replaceable skid pad running longitudinally along the bottom of the pontoon. Vertically oriented gussets are positioned on an interior of the pontoon, to provide structural integrity and additional strength. In a preferred embodiment, a buoyant foam is provided within the interior cavity of the pontoon.
