Easy to capsize upwind, when it pulls a wheelie coming up off a wave, and then nose dives on the landing.

That was the issue we were talking about when the Nacra 20 came out, remember? It seemed it would be a whole lot more difficult to find the right balance point going upwind and down, with the middle of the boat trying to lift up.

You are now riding a teeter-totter.

JC's Sarah mentioned it in one of the early interviews.
