The V-shaped cable fastener is part of the (Foil Assist) mast sets but can also be purchased as a spare part. This cable holder, made of durable, lightweight plastic, ensures that the cable runs neatly along the underside of the board without bending. Additionally, it keeps the cable away from the propeller and reduces drag from the cable in the water. The cable fastener is securely mounted at the end of the foil box using two screws and track nuts.
