The Indiana mast profile ensures amazing flexional and torsional stiffness. The aluminum masts transmit the control impulses very quickly and directly from the board to the foil. Depending on the area of application and skill level, three lengths of aluminum masts are available. 50 cm are ideal for beginners and schools. For SUP, surf, wake and wing foiling, 75 cm is the ideal length and for everyone, the kite or wind foils are well served with 90 and 105 cm.
