This weed-less swept back skeg is great for those who would rather not get hung up on weeds or drag them along. The 13" long swept-back design works as a weed-less rudder that minimizes yawing (side to side swinging) during paddling stokes and assists with forward propulsion due to its reflex technology. At only 7" deep this skeg allows you to travel in much shallower waters. Large (13" Long x 7" Deep) swept back removable slide-in skeg can be used with Stand Up Paddle Boards, FastTracks, Explorers, and Travel Canoe. *Note your craft must have the grooved base plate to accommodate a slide-in skeg.
