Mark,
From all the owners that I have talked to the boat is great.

The only issue I see is the sometimes lack of stability.. getting too much lift off the boards.. The problem is that the boat was designed just before a MAJOR shift in foil technology before that last AC. Keep in mind that curved foils have been used for years on other boats like the M20 and nobody seemed to complain then. The olympic folks are just pushing it harder trying to get max lift.

I have spent 3 years on a Nacra F20c and this year I put some winglets on the rudders. Wow what a difference. I can push it harder, get more lift from the boards and have more control. I can tell you.. once you sail a boat with lifting boards you won't go back..
