Hi Will,
Consistency is a part of quality. I too wish the T clas would go for three different stiffness masts but I do not think that is in their plan. "One size fits all". It is a good thing the rules makers don't think like that in Olympic track events and make everybody wear the same size track shoe because that is more "ONE DESIGN".
The outcome of an Olympic caliber catamaran race is much more highly affected the normal variation in crew weight than in the location of crew weight along the hull to minimize the inertia of the sailing system. The rest has all been said before so I am not going to say it again. Some day the rules makers will finally get it right.
Bill
