Carl,

With all the different configurations, it is not fair to stick everyone with the same number. US Sailing already provides modification factors for the boats and that is what I use when sailing in P/N races. I mulled over this for quite some time with no solution. Even if we came up with some number for the max allowable sailarea, I don't think anyone would really be using that much sailplan anyway and that to me is not fair.
Our rules are loose enough to cause this problem and that is why the P/N mod factors are a good choice to use. The F18 class is alot more stringent and can come up with a number.
