I've definitely been out in stuff I probably shouldn't have been out in, limped to the lee of an island, dropped sail, and sailed back under mast alone (doing 11 knots). I also Had it out in a distance race a few weeks ago and the wind changed dramatically and started gusting to the upper 20s...and I was on a long a reach wishing like hell the guy ahead of me in 1st place would get off the trapeze so I could justify getting off the trapeze ;-) (definitely found a condition where a pre-foiling DNA with curved boards has an advantage over a straight board A-cat!).
