Oh my Phil,
This is absolutely FANTASTIC!! Honestly, I think if you can find a permanent builder for the boat, this class may take off. You should offer options as to home building or buying from a builder. Also, I know this may be a bit off topic, but I was looking through a Harken catalogue, and noticed they had a diagram of a beachcat that showed parts used. It was odd however that in this diagram, the cat's mainsheet system was behind the tiller crossbar. It appeared as though the tiller arms were longer, and the tiller crossbar simply was in front of the traveler tack with the tiller extension attached. This appears to be much more simpler rather than passing the tiller behind the mainsheet blocks every tack/jibe. Perhaps this could be a feature on the F12 due to its ease of use?

Well, anyways, I am very excited to see that you are going forward with this great idea and I can't wait to follow your progress. What is the website this will be posted on by the way?
