Abstract: A surfboard is formed from a pair of lightweight shell elements which may be of a polycarbonate which is see through, plexiglass or other material having a high strength and low weight. The two shell elements are joined together to form an airtight and water tight sealed hollow unit. The shaping of the shell elements is in accordance with conventional surfboard requirements and the tail and nose are made removable so that these components can be substituted to satisfy various surfing requirements. A pressure valve is provided for injecting pressurized air into the interior of the shell and through way valves are provided for the nose and tail to allow the nose and tail parts to maintain the same pressure as the main body.
