ABSTRACT:
An improved water sports board having a low density high strength elongated core surrounded by a contoured exterior layer formed of soft resilient non-permeable material. The elongated core, substantially rectangular in plan shape and cross-section, tapering forward and aft, and constructed of low density light weight material covered by a high-strength composite skin, renders the board light and strong, and promotes controlled flexion, resilience, durability and maneuverability. The soft, resilient exterior layer forms the board's outer shape, promoting performance and rendering the board safe and comfortable to ride. Alternative embodiments in which the core contains of one or more cavities filled with gas, the pressure of which gas can be selectively varied before or during use, are also described.
