Abstract
A strong, lightweight laminar device which can be used as a fin attachment for surfboards and sail boards, or as a skateboard, sailboard or surfboard, per se. The device comprises a lightweight core and one or more layers of strengthening material surrounding the core. In fabricating the device, a suitably shaped mold is lined with a strengthening layer of carbon fiber. A separating layer of random glass is placed between a first strengthening layer and a second, similar strengthening layer. The space at the interior of the lined mold is filled with an appropriate lightweight, buoyant filler material such as polyurethane foam. After the filler is set or cured, the device is removed from the mold and treated or assembled as desired.
