Rich, I've only been on 2 F18 platforms, the Tiger and my Infusion. I am very happy with the Infusion, downwind it is extremely forgiving (coming from the N20, also very forgiving), and it tracks like it is on rails upwind.

I think all the major platforms are fast in capable hands. My take is the Wildcat has the narrowest groove and is the most difficult to sail downwind, difficult being relative (I watched as Mischa walked away on his in narly conditions). Many of the good U.S sailors in the class are on C2's, for what that's worth.

Truthfully I would get the boat with the best dealer support. There are also plenty of nearly new used boats on the market that I would be picking before a brand new boat.
