ABSTRACT:
A surfboard having a resilient bottom panel which extends rearwardly beyond the rigid deck, this being accomplished preferably by splitting the rear portion of the board along the siderails to define a rigid rear deck spaced above a reinforced resilient panel defining the rearward continuation of the board bottom, there being a watertight flexible tailpiece fitted around the deck and over the bottom panel to form a smoothly contoured termination of the board at the rear and retain the hydrodynamic advantages of a conventional surfboard. The advantage of the invention lies in the ability of the trailing portion of the board bottom to flex in response to varying water pressure beneath as the board is being maneuvered, and one or more adjustable lever arms limiting the upward flexure may be provided beneath the rear deck.
