Fins provide you with control as you shift weight, steer the board, and turn. The X-Sport is the only jetboard in our G3 Line that comes with quad fin boxes. Try using just one fin pair for added speed and stability, or take advantage of the full quad setup to maximize grip and control.
All fin boxes are made with FCS-II Standard Fins. You can order different sized FCS-II Fins from your local surf shop or any online retailer to further customize the stability of your board.
