Adjustable surfboard

In a surfboard assembly, the combination comprising

• a) said surfboard being longitudinally elongated, and including a longitudinal sequence of sections, there being a lateral split between sequential sections,
• b) and releasable attachment means rigidly interconnecting the sequential sections at said splits,
• c) said sequential sections having substantially flush upper surfaces and substantially flush lower surfaces, and said attachment means confined between the levels of said upper and lower surfaces,
• d) said attachment means including:
• i) connecting structure penetrating longitudinally into said sequential sections and including loops at said splits, and
• ii) connection pins inserted laterally through said loops at said splits, the pins being withdrawable laterally from said loops,
• e) said connecting structure including anchors penetrating longitudinally into said sequential sections, each anchor integral with a loop,
• f) said sequential sections having generally longitudinally extending edges which are laterally spaced apart, said pins extending laterally between said edges, each pin having shoulders at opposite ends thereof to engage the sections proximate said laterally spaced edges, for retaining the pin in inserted position,
• g) the sequential sections having longitudinally abutting surfaces at said split,
• h) the sequential section edges being recessed to form C-shaped recess sections which together for a circular recess, the pin shoulders received in said circular recess.
