Abstract
A method for making a surfboard includes a foamable material sheet cut into a number of panels and disposed in a mold device for hot pressing the panels and for expanding the panels to a prototype having a volume about 6 to 10 times greater than that of the panels. The prototype is then hot-pressed again for further expanding the prototype to the surfboard having a volume about 2 to 3 times greater than that of the prototype. The mold cavity includes tapered peripheral portions for forming tapered sides and tapered nose and tapered tail for the surfboard.
