ABSTRACT:
A surfboard that has a hollow inner volume which contains a longitudinally oriented reinforcement system or spine, with laterally arranged branches or ribs. The reinforcement system is spaced both from the nose of the surfboard and from the tail of the surfboard, while the ribs or branches radiate from the spine towards each side of the board in various spine and rib configurations to provide an optimal balance between weight, strength and flex.
