yes, the weight and the uni defined the ht in my opinion.

And yes I agree that if the rules were opened up then the boat could still and probably would likely mostly be sailed as a uni.

If you wanted to really do something interesting, I would get rid of the max beam rule, the uni rule, the spin hoist height rule, the foiling rule.

And just keep the 18ft long, 165k min weight, 20sq up, 40 sq down and it has to be a catamaran. Make it 2 man development class. Kind of a mirror of the Acat rule set, but for two people.

That might be more interesting.
