Abstract:
A surfboard includes a core covered with a laminate and having curved perforations in the deck area and the tail area of the surfboard, in order to prevent air blisters from forming between the core and laminate. The curved perforations are deformable under pressure to minimize the opening of the perforations to inhibit liquid from entering and maximizing under zero pressure to allow the maximum amount of trapped liquid and gasses from escaping. The core is formed from an extruded closed-cell polystyrene foam block that has been shaped by restraining it against a shaped form using shaped restraining tools and straps, and heating it; and by cutting using a hot wire. The core is laminated with FIBERGLAS® and epoxy resin, and the perforations are formed using a perforating tool that has a planar or curved working surface and one or more heated needles extending perpendicularly from the working surface.

Claim (Index 10):
The surfboard of  claim 9 , further comprising a stringer located internal to, and along a centerline of the foam core, wherein a first portion of the deck perforations is located on one side of the stringer and positioned in a straight line parallel to the stringer, and a second portion of the perforations is located on another side of the stringer and positioned in a straight line parallel to the stringer and the first portion of the perforations.
