<p>The surf board, which can be fitted with a sail, consists of a pneumatic airtight bag (1). On the two long faces of this, panels (2,3) of marine laminated material are bonded. The periphery of this has an edging (16,17) of supple elastic material. The base is made of two panels of airtight fabric (7,8) that are bonded together at their edges (11,12). The laminated panels are bonded to the inner surfaces of the fabric panels or to their outer surfaces. Fabric cross pieces (12,13) join the ends and the centre of the long faces of the bag.</p> |
