So are you suggesting a beam specification of between 8'6" and 10' for the F-20 class? I can agree with that. Reason being that there are so many Nacra 20's out there, but the new Nacra F20 Carbon has the 10' beam and, like you said, there are the Tornado's to consider.

Let's talk sail area specs. I wrote "I have seen several posts rating the Nacra 20’s sail area somewhere between 192-194 sq. ft. for the main sail (without mast), 53-57 sq. ft. for the jib, and 270 sq. ft. for the spinnaker. This appears to be an accurate perception based on what I’ve seen except for the jib, which I feel tends to be closer to 53 sq. ft. Is there anyone that would like to chime in on these specs for a proposed F-20 class in America?"
