Tell Me About the Alu Mast. Let Titouan tell you more about our aluminum mast and all its advantages. The F-ONE aluminum mast can be used in all disciplines: kite, surf foil, wing foil, SUP foil and windfoil. The shape of its section benefits from our years of experience in kite foiling to provide the best gliding feel while keeping the strength up and the weight down. #fonewing #fonefoil
