Bill: I was under the impression that carbon masts was better when beating into chop, as the leverage of the mast was less. I tought perhaps this was where the performance might be improved..
If you read the german class ballot information. They say that the carbon mast is neccesary to stay competitive, but dont present any empirical data for this.. I dont know any more.
They also say that it will indeed be neccesary to re-cut the mainsail. But that this is a feasible job to do on a present mainsail.
Regarding weight, this is information that is not finalized. It does not say anything about changing platform weight in the proposed rules (as far as I can se..).
Interresting times..
