Ohh, this question is easy to answer.

The whole idea of a formula rule setup is to have the boat converge to a setup that is the fastest UNDER the giving rules. Maybe the fastest F16 setup is to be found at a boat weight 20 kg higher then the class minimum weight ? What is so wrong with that ?

If this is proven beyond a doubt then the other builders will simply converge to the same number and all is fair. If the reverse is proven then the minimum weight of the class rule will see all boats converge to that over time, even the Viper.

The idea of he weight rule is to limit very exotic construction and therefor limit cost. It is of no importance whether that limit is set by some class rule or law of physics as long as it is set a value that is not to far out there in the way of costs.

In the mean time the class improves itself gradually like other formula classes like the F18 have done. Back 1995 the Nacra Inter18 was dominant, then the Tiger, then Capricorn and now the Infusion. Next year the Wildcat or new Carpricorn again ?

I don't see any instability arising from this situation.

I have never seen the F18 class being in trouble because the 1995 Tiger was no longer of the same performance with regard to the Infusion. Did you ?
