Personally I think the rules at this stage are still way open to negotiation given that very few people had an opportunity to have a say in the development of them in the extraordinarily limited amount of time given for discussion, and I for one think mast height needs to be discussed further so if you're thinking of cutting a mast, I think I'd wait a while. I really don't think we should be rushing this for one regatta and I'm sure the organisers would accommodate a boat with a slightly taller mast anyway if that's what you really want to do at this stage. Personally I'd be building the rig I thought was the most efficient for a 14ftr rather than working to an arbitrary number which may or mat not be best for the class. I also have the suspicion that the mast height was deregulated in subsequent posts on the subject but I like you all, am not sure exactly what's going on.
We should probably just be having some fun with it for now to see how things develop.
