Water sports board

A water sports board comprising:

• (a) an elongated core, substantially rectangular in plan shape and cross section, tapering forward and aft, composed of a low density fill material enclosed within a high strength composite skin;
• (b) a contoured exterior layer formed of low density soft resilient non-permeable material adhered to and encapsulating said elongated core;
• (c) said core having a shape, relative thickness, and composition which combine to allow a degree of longitudinal and torsional flexibility sufficient to vary the board curvature under load and promote board maneuverability;
• (d) said exterior layer having a shape and composition which combine to promote board flotation, performance, and flexion control,
• wherein said elongated core is strengthened using stringers.
