Good point NYKiter,
even if in other context discussed a few times seen here, maybe someone finds the topics. Foil in lines is one of the points which makes me thinking foiling should stay an "experienced only" kite sport, even if the new foils are getting easier and easier to ride, otherwise I fear we will see somebody drown in the next time fixed to its foil by kite lines.
Most important reaction for me is:
1. Try to understand situation in the first secound as far as possible and emediately act in the secound
2. Action most time will be kill kite power, but not by quickrelease which most time won't work, but most time by pulling in one or both stearing lines to cut the flow from kite profile.
Also had foil maybe 6 times in the lines and last one a few days ago. Don't remember, but could have been a to high backflip where the foil ended in between the pretty low Y of front lines. As in this case first check showend kite still in normal flight at 12 and bar free, I decided and was able to pull the foilwing out of lines during flight. But happily it was just a monofoil.
But found a slight damage in the lines at this point, so will have to shorten and everybody should check well after crashes. Also a smove foil trailing edge is also important for that, if you have unthreated dings in your trailing edge they can act like a serrated knife at your lines and your body!
