Red Paddle Co have collaborated with FCS, the world's leading fin manufacturers. The Touring 9 fin comes with a nut and bolt connection to ensure a 100% secure hold and comes with our Sport and Voyager boards, as well as any of our previous touring boards such the Explorer. It is compatible with all US fin boxes.
