Abstract: A board-type watercraft is adapted for selective disassembly into a plurality of separate sections for ease of transport and storage. Preferably, a selection of differently configured nose and tail sections can be releasably connected to a universal middle section to create a wide variety of distinctive board styles. With the watercraft in its assembled state, adjacent sections are releasably secured together using compressive-type fastening elements, such as spring-biased latch mechanisms. Pairs of fastening elements are preferably arranged on the top and bottom surfaces of the board in substantial vertical alignment to limit torque between sections and thereby ensure adequate stiffness through each joint. In its disassembled state, the sections can be stacked into a highly compact configuration suitable for packaging within a container that is compliant with maximum size standards for conventional ground courier services.
