You forget Nacra 17 for the choice and the fact that Tornado disappear because of uncontrolled evolution.

I sail F18 till 1994, and you ?
You miss the point, the point is not more rule, it is simply to apply the rules.

The spirit of the F18 rule is real sport when the boats are as similar as possible.
If you need a faster boat to be ahead I suggest to improve your sailing skills.

Do not forget that Formula 18 was created, in France, in order to prevent technical "arms race" in technical cat.
This is the key of the F18 success.

The more you're twisting the rule, the more people think F18 is no more fair.
F18 is not A class nor C class. It is close class rules.
