I would not have wanted to be the owner of a boat that chops and changes the mast heights every couple of years. 4 times in 12 years would turn anyone off purchasing a Bim. It would especially destroy re-sale value of second-hand boats as new masts and sails are considerably expensive, and by Maurizio's reasoning if you did not do this then you are uncompetitive.

At least with a box rule this kind of haphazard changes to the rules would be minimal. Maybe something for Bim to consider.
