Like I said how many times can you be wrong in one single thread ?
the new class rules want more weight instead of being the original design weight of under 50kg.
I'm working on these rules right now; most working on the wording rather then the numbers or intent of the rules and your "assumption" is unfounded. The F12 never had an orginal established weight rule as we never reach agreement on it till recently. But even in the proposed rules the ready-to-sail weight was never "under 50 kg"; I don't know where this perception is coming from. The most original F12 rule come from me and had a 60 kg minimum weight limits, that in fact WILL BE lowered in the new class rules as a result of the recent discussions on this matter. So as a FACT the new (proposed) rules will indeed "want" less weight rather then more as you have errornously stated.
Forgive me my inflammatory style of writing but I have a hard time "understanding" anyone making a fuss without having checked the validity of his claims before hand. And checking your facts is such a simple thing to do with the internet these days !
