Innovative solution to mount a foil on board in 30 seconds. 4x M8 strainless threaded rods are premounted on the board using existing T nuts, gently pushing on the bottom of the US foil box, maintaining the right longitudinal position of the foil on the board. Then, just plug the on your foil on 4 threaded shafts in preset position, and fix it by hand screwing our Hydro shaped foil Fix nuts. You can then go and foil 20s later! The shape of our nuts are designed to allow lowest hydro drag before taking off! An extra small power tool is supplied to apply more tension if needed, or facilitate the uncrewing of the nuts after your session.
