ABSTRACT:
A variable flexible bodyboard comprises a lightweight, generally elongated, foam core material having a top skin layer and a bottom skin layer with a front nose end and a rear tail end. The bodyboard has also an elongated stringer element having a one end and an other end, and composed of at least one stiffener material, of a defined length, to impart stiffness to the bodyboard, and at least one flexible material, of a defined length, to impart flexibility to the bodyboard. The stringer element is positioned and secured within the foam core material of the bodyboard; and a helical spring is disposed within the stringer element imparting additional resiliency to the stringer element.
