So, as I read your post Brian you are saying that it really is up to the actual "class" to decide which way they are going to go? That sounds completely logical to me and should offer the right information to all concerned who are interested in the stability and proliferation of formula racing
I don't know about Australia, but in the U.S. we do not yet have a United States Formula 16 Class Association.
Which comes first: Waiting until there are enough boats to form a class association, or forming a class association and promoting it and trying to get more boats into that class?
In either case, it is not conducive to building the F16 class if there are two separate handicap ratings for uni and sloop.
In the United States it still is not clear whether there is any strong commitment to the Formula 16 concept on the part of the Taipan 4.9's here.
