I was told this came about because last year, they used the Inter 20 and crews tweaked their own rigs, but when they swapped boats, the settings were all different, so it was harder for the crews to adjust to.
I don't know how anyone could tweak any of the boats at any of the Alter cups to personal style. I went to some of the planning meetings prior to last year's Alter Cup. There was a clear understanding that you weren't allowed to change ANYTHING other than maybe sheeting angle on the mainsheet blocks. The beach captain this year was the same as last year and he is a quality guy who would not allow any screwing with the rules. Aside from that.. hard to see how anyone could change anything in the rig in the 10 minute change over period.
