Most of the A-cat discussion goes on in the google group for it that has about 150 members. you can find it via the the a-cat.us site. Some also on Facebook at the USA A-Class page. Some posts on Sailing Anarchy too.

This site would be a good place for more discussion as is very focused.

Since the boat is 7.5 feet wide, it makes things easier. Masts are 9 meters long I believe.
