I surf foiled the F-one SK8 850 foil. I was mostly testing to see how it handled wing tip piercing the surface, and how it performed in head high plus long period swell.
In this video I show what happens when the wing tip comes out, and compare the SK8 ride characteristics to the F-one Eagle, Seven Seas, and Phantom foils.
Also there are additional videos of a short wing foil session speed test, and another surf session in small gutless surf.
Thanks to Olivier at Covewater for letting me demo a SK8.
