Claim:
A method of manufacturing a surfboard using a shaped surfboard blank having peripheral rails, a top side and an under side, the method applying carbon fiber material to substantially only the rails of the shaped surfboard blank and enveloping the carbon fiber applied rails and the shaped surfboard blank in a non-carbon fiber laminate, wherein each rail extends from the top side of the shaped surfboard blank to the under side of the shaped surfboard blank, each rail having one rail side extending from a periphery of the rail to the to under side of the shaped surfboard blank, said method comprising: (i) adhering carbon fiber material having a unidirectional weave to substantially one side of one of the rails of the shaped surfboard blank, the weave being generally aligned with a longitudinal axis of the shaped surfboard blank; (ii) laying fiberglass matting over the carbon fiber material; (iii) applying resin to the laid fiberglass matting; (iv) adhering carbon fiber material having a unidirectional weave to substantially the other side of the one rail, the weave being generally aligned with the longitudinal axis of the shaped surfboard blank, (v) laying further fiberglass matting over the further carbon fiber material; and (vi) applying resin to the laid further fiberglass matting.
