<p>An improved water sports board having a low density high strength core (18) surrounded by a soft resilient exterior layer (26). The elongated box-shaped core, constructed of low density light weight material (20) covered by a high-strength composite skin (22), renders the board light and strong, and promotes controlled flexion, resilence, durability and maneuverability. The resilient non-permeable 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 can be selectively varied, are also described.</p> |
