The Severne FoilGlide is purpose built for foiling from the ground up. This is NOT just a freeride sail with ‘Foil’ written on it. A lightweight sail is optimal when foiling - and Severne makes light weight sails better than anyone! With five battens, you won't believe how light it is in your hands. Since your sail is not as "loaded up" when you are foiling, the sail can be softer and easier to pump than your traditional freeride sail, but with two cams, the draft is still super stable so you can easily stay balanced over the foil. The short boom length, combined with a tight leach gets you up and foiling with a small sail even in light winds.
This is the Foil Sail for the IQ Foil Junior package but it works well for adults as well. This is a game-changer for foiling esp in lighter winds.
