I smell what you're stepping in. Went over in a hurry once w/ my son on the wire– he came flying past me in a blur and into the sail maybe 5' above the foot. We had so much rolling momentum, the boat didn't even think about stopping. We turtled in a heartbeat... ah the joys of sailing on a gusty inland lake. He is light enough (and went into it flat enough) so the sail was unscathed.
More recently I took that ride from the wing, but just sitting on it. A gnarly, rogue gust nailed me while asleep at the wheel and I put my leg through the bottom panel near the window. That sail was seriously delaminating anyway, so I am now the proud owner of a pentex square top. It seems to me there is not a lot room between the sail & tramp to fall from the wing, whether trapping or sitting. Holding on and lowering yourself down either side is the obvious plan but I seem to have a shortage of hands (with the sheet and tiller to tend) when a capsize is looming.
