Bill,
If Uni is what you like opening up the rules will not prevent you from sailing it as a Uni. However the current set of rules do prevent you or anyone else from sailing as a sloop. With the F18 being 180kg I thought the thing that defined the HT as a class was its light weight.

Phill

I know that the voices in my head aint real,
but they have some pretty good ideas.
There is no such thing as a quick fix and I've never had free lunch!
