Forget the current rule set, just design a 16ft boat along similar ideals to the F16 class.

What would I do, a chopped off DNA with inclined 20 degree boards ( C boards would be nice but to keep the cost down ), front beam moved foward slightly to cope with a 14sqm main and 2.5sqm jib, A class mast, 16sqm spinny, 100kgs all up to allow for a glass build.

The FX1 and I17 failed for very obvious reasons, they didn't sail well as a single hander and couldn't sail well with two crew on board and were over weight.
