ABSTRACT:
The invention is directed towards a watercraft module and a connectorless sea train including two or more of the watercraft modules. The watercraft modules in the sea train are formed in a bow-to-stern relationship and are held together by compression forces. Each module includes a hull having a bow end having a substantially V-shaped profile, and a stern end having either a continuous end or a substantially V-shaped notch cut therein. The size and shape of the substantially V-shaped notch is substantially similar to the size and shape of the substantially V-shaped profile of the bow end. In the sea train having two or more watercraft modules, the substantially V-shaped profile of the bow end of a trailing watercraft is received in the substantially V-shaped notch at the stern of a leading watercraft.
