I am a heavy guy 100 kg. Kitefoiling for 5-6 years now. My spot is a low wind area, most of the time we ride in 9-12 knots.I don't switch my feet easily butI am very confortable on a foil.I have a T38 17 L SABFOIL board (45 x 125 cm) which is a very good board, but old ... With 93 cm mast and a 633...
