Abstract
A pontoon boat is manufactured using sectional pontoons of rotationally molded thermoplastic material. The pontoon sections are engaged end to end using integral lugs and sockets on the ends of the pontoon sections. Each section has a head located above the main hull portion of the pontoon. Channels engage opposite sides of the heads and extend along the pontoons to ensure the coupling of the pontoon sections. These channels also couple the pontoons to a deck carried on transverse beams joining the channels.
