ABSTRACT:
Lightweight, high-strength flotation devices such as surfboards, sailboard and body boards that can be inexpensively manufactured from plastic sheet materials using thermo-vacuum forming techniques. The devices include specially configured structural cores which provide strength and rigidity to the devices. The structural cores are, in turn, encapsulated between specially configured upper- and lower-shaped panels which add strength to the devices and create a sleek, finished appearance.
