Granted I've only been out on my nacra 3 times (once with strong winds) - but pitchpoling just seems like less of a threat with this boat. The hulls stay well above water and seem buoyant enough that it would take some pretty big waves and a tight turn to sink one.
I think the lesson here is: don't tack too fast with a late 70's hobie 14 in strong winds and choppy water!
