Jeff, the NACRA I sail is the slowest one, a 4.5 with 14sq spin. But I'm a novice in my first year of club racing. I sail against that F18 and I haven't seen it pitchpole, often seen it capsize but generally because of spinaker troubles or they are unable to depower it in heavy breeze, once I finished ahead of it

I will be in Padthaway for grape harvest 2010, may make your race. Thinking of upgrading to a second hand F16, but I know from my previous sports you get more satisfaction beating others on inferior kit.
