Abstract
An improved water tight, chambered planing pontoon assembly incorporates a hollow shell with a cross sectional shape in the form of an upper portion and lower portion. The upper portion of the shape is generally semi-cylindrical extending downward and terminates with opposing chines extending the full length of the tube. The lower portion of the shape is formed by equal and opposing planing surfaces which extend upward at acute angles from a vertical center line, then turn outward, perpendicular to the vertical center line, meeting at the chines. The tube terminates on the bow end with an elongate semi-cone and on the opposite end with a water tight bulkhead. The upper and lower portions of the tube are formed of one homogeneous sheet of metal. The semi-cone with opposing chine portions is formed of one homogeneous sheet of metal.
