ABSTRACT:
A sailing system in the form of a sailboard apparatus (20) having a board (22), a mast (24) extending upwardly therefrom for supporting a sail (28). A plurality of elongate, flexible battens (30) extend through pockets (31) formed in the sail (28) to engage with corresponding batten sockets (32) disposed within the sock portion (80) of the sail. Each batten socket (32) includes a forward arcuate portion (110) adapted to swivel about mast (24) and rearwardly extending, arcuate side flanges (112) defining a narrow gap (114) for receiving batten (30) therein. A fabric hinge (118) restrains the forward end portion of the batten (30) against forward movement toward the mast (24) while being substantially free from restraining the forward end portion of the batten (30) against side to side movement between the socket flanges (112) in response to changes in the curvature of batten (30). The bottom socket (32) imports a bending moment on the batten (30) to increase the curvature of the forward portion of the batten, thereby contouring the side (29) so that the maximum draft is located on the forward portion of the sail (28).
