COMMITED TO FLY. DOES A FOIL MAST ABSORB CHOP?DOES THE PROFILE, OUTLINE, LEACH LINE OF A FOIL SAIL LOOK LIKE A NORMAL FIN SAIL?DOES A FOIL SAIL HAVE THE SAME PRESSURE AS A FIN SAIL? These are just 3 main questions that can be answered the same. NO.Therefore in Point-7 we have decided to develop dedicated masts to enhance the performance of our foil sails, exclusively for those who don’t want compromises in performance.
