For means of comparison (sorry, no crash here):

A little air triggered by a small wave - and a crash avoided by awareness and proper reaction.

Traveling in approx. 13 m/s cross offshore wind on a Tabou Rocket 95 with a NP Search 5.4.
It's the same sailing session as as in sequence "2", but this time our guy's a little more lucky. Compared to "2" he's going a bit closer to the wind (not broad reaching), and perhaps that's decisive for his luck? Again he hits a little steep wave in the back, and the nose of the board lifts a little.
Only the fin and the utmost back of the board still touches the water. Because of his course closer to the wind he's further forward on the board, and that should help him a little to keep the balance and ease the pressure on the fin. The board lifts nicely out of the water. Our guy's lifting the windward rail a little, allowing the wind to give him further air. Now, the question is, if he's prepared to actively lift the back of the board with his back foot and turn a little to leeward ...
Yes, he's hanging nicely in the air a couple of inches above the surface. His bent legs, the (laterally) level board and the sailing direction a little more downwind indicates the good prospects ... He has placed the board on the water again in a controlled way and has resumed his original sailing direction. No panic - at least for now!
