I thought the whole idea of F14 was to develop a formula which promotes innovation by allowing some development in 14ft cats. If you are advocating 'sub' classes within the formula with varying yardsticks/Portsmouth numbers it really defeats the purpose of the class as I see it. I mean there would be no incentive to continue to develop your boat, a. because you would already be competitive on yardstick and b. if you continued development the boat would simply attract an equalising Portsmouth number and nothing would be gained. This is assuming that some miracle formula could be developed to make all the various configurations equal in the first place which is almost impossible.
No IMHO F14 must simply be scratch racing and if you want to race under a Portsmouth number, best leave the boat 'existing one design' class legal.
