Kris,

Good luck finding one. My sense is that no one knows (or cares about) the difference. If I had to guess, the folks that started it all probably actually thought they were creating a formula rule.

I highly doubt you're going to get a "definitive" answer, especially here...

I still struggle to see where this would matter to anyone, other than maybe a Volvo or AC-level boat builder. Even the sponsors at that level care less about the boat rule, and more about the event (prestige, ROI, etc.).

Are you putting together a campaign? That would be COOL!!!

Mike
