Abstract
A new surfboard and method for making a surfboard out of wood so that it will be lighter and stronger than any heretofore produced. It is a method of construction using sheets or panels of wood, separators or spacer blocks between those sheets, which could be of light wood or plastic foam and finally rail or edge pieces also of light wood, balsa, that are subsequently glued to the aforementioned core of sheets and separators.
Claims10
A method of constructing a surfboard comprising the following steps in substantially the order named:
- (a) providing two panels, of slightly less width and substantially the same length and plan configuration as the desired surfboard, to be used as the top and bottom skins;
- (b) inserting a set of separate and discrete spacer blocks of light weight strong material between said top and bottom skins, said blocks being of critical and varied height dimensions and critically located so that the assembly duplicates the thickness dimensions of the desired surfboard, applying glue to the interfaces of the blocks and skins, and forming the assembly in a jig while the glue sets to achieve the desired longitudinal, generally concavo-convex edge profile of the surfboard;
- (c) building rails onto the vertical side edges of said assembly in the form of vertical laminae pre-cut with the same generally concavo-convex profile and of light weight, strong, water-insoluble material, the laminae on each side being glued together and glued to said vertical side edges;
- and
- (d) smoothing, finishing and coating the surfboard.

A surfboard comprising:
- (a) two similar panels of light weight, strong waternonsoluble material, extending substantially the full length of the surfboard and spaced apart to comprise an upper and a lower skin;
- (b) spacer blocks, separate and discrete from each other and secured to and between said panels, said blocks being of graduated varying height dimensions, and the thus assembled panels defining a generally concavo-convex assembly with both forward and tail ends tapered both horizontally and vertically;
- and
- (c) side rails on the side edges of said assembly, each side rail comprising a plurality of vertical laminae secured to the panels and the ends of said spacer blocks and closing the spaces therebetween.
