Fits the Wilderness Systems Kaos and Dagger Koas surf kayaks (same boat!). The Koas typically takes two small fins (skegs) on the sides and one large fin (skeg) in the center. Fins can be used in any combination you see fit. It is assumed that these fins may fit the Wilderness Systems Alamax sit-in surf kayak. Fin depth is 2 1/16 inches. Fits a 9 1/16 inch skeg box, screw holes are 8 3/16 inches on center. Includes two brass machine screws. (Stainless steel is not recommended but can be used.) The addition of skegs adds performance, increases the ability of the kayak to hold position while trimming along the wave face and aids in tracking. Surfing the Kaos without fins allows for 360 spins. See Kaos Surf Video II. Fins can be damaged in by shallows, reefs, rocks and in white water rivers. Instructions are included.
