Coupling system for a multiple sectioned boat

A system for joining together at least two independently buoyant boat hull sections to form a singular vessel, said first and second boat hull sections each having a hull panel and an interface bulkhead which flushly mates with a corresponding interface bulkhead in an adjacent hull section to be attached, the system for joining said boat hull sections comprising:

• at least one threaded fastening means which is mountable through the upper areas of said first and second interface bulkheads for positive clamping together of said first and second bulkheads above the waterline, said first and second interface bulkheads having alignable passages which are coaxial when the first and second hull sections are joined and receive the fastening means;
• at least one rigid elongated pin which resists flection along the interface, said rigid elongated pin being anchored near the waterline, and being mounted through said first bulkhead and embedded in a rigid watertight block firmly and directly attached to the bulkhead and the hull panel it adjoins;
• said second bulkhead having a watertight recessed socket with a closed end securely embedded in a rigid watertight casing, said socket firmly and directly fastened to the bulkhead it adjoins, and said casing being firmly and directly fastened to the bulkhead and the hull panel it adjoins;
• said socket being dimensioned to correspondingly engage in a ready and snug manner and said elongated pin.
