Hi , what type of sail is that? Sure its a speed sail but I can see that the whole area from top to bottom has 'soft' areas for high wind control, is that a custom sail ?
You can't post a video with an usual sail, and not provide some information about it when people ask you. Going fast in flat water is no big deal... You've earned another thumb down my friend.
Sorry, i'm a video maker not, a windsurfer... I don't know the answer, the only thing I know, it's that it's a Mistral / Gasoil prototype. Gasoil usually makes fins ailerongasoil.free.fr/
