Abstract:
1. A modular sponson for a boat having a bow, sides and a stern comprising: a plurality of discrete sections disposed in a series from said bow and along both said sides to said stern of said boat, each of said sections having an axially extending length of tubing defining a longitudinal opening, a plurality of elongate pieces of closed cell foam material secured to the outside of said tubing for substantially the entire length of each section, means outwardly disposed from and in contact with said elongate pieces for creating flotation structure, and a protective covering on the outside of said flotation structure creating means and reaching inwardly to opposite ends of each length of tubing, said elongate pieces of closed cell foam orthogonally extending outward from said tubing for substantially the entire length of each section of said series; an elongate cable extending through said longitudinal openings of said series of sections, said cable exerting a tensile force holding said series of discrete sections adjacent one another in compression, and sections of said series in said modular sponson having substantially the same lateral and longitudinal outer dimensions; a bonding agent disposed on mating surfaces between each length of tubing, elongate pieces, and flotation structure creating means; a pair of end plates each having a hole, each of said pair of end plates being on a separate aft end of an end one of said discrete sections of said series on opposite sides of said boat at said stern, said cable extending through said holes in said end plates on end ones of said series of discrete sections; and securing means at opposite ends of said elongate cable for engaging said end plates by said cable.
