What if you could submit a polar for each boat to USS portsmouth committee? I thought someone said there's a smartphone app that draws one up.

Get the best sailor on the boat to drive it for a while, get the polars and crunch the numbers into some sort of DPN/PN. Then you wouldn't have to worry so much about individual mods, but rather how they all work together (or not) to make the boat faster...

I'd bet Randy's sew-sew from EC might have done pretty well at Mug, too?
