Abstract
A control device for a surfer's sports kite has a hand-holdable elongate control bar for steering the kite. A central control line is used for changing the effective curvature of the kite and therefore the power generated by the kite. The control device includes an open-top body mounted at the center of the control bar and attached to a harness loop. The harness loop is arranged to be attached to a harness hook of the surfer in use. A stopper fixed on the control line fits in the body. On the one hand, the stopper is shaped to maintain the line (and hence the harness loop) in particular orientations for ease of fitting the loop to the hook. On the other hand, when the ball is moved to the right in the Figure, the ball is free to rotate to allow the surfer to untwist the control lines, when required.
