Slab said..was that a small sized foil as it didn't seem to give heaps of lift that easily.....not that I really have a clue
For what I see, Casso is delaying the liftoff on purpose as long as the wave is not foiling-friendly (too hollow/unsteady). This is because foils give heaps of lift easily, and the hard part is keeping them from breaching the surface as soon as you let them lift you off, and this is a very delicate timing going down a steep face. Delaying foiling till the slope is less steep is a good strategy.
