Two comments I would like to make. I think that even within the USA we find some of the same closeness and distances as one would experience/feel in Europe between countries.

I would like to see an America's Cup format where the racers and production of the boats were specific to the country who's flag they carry. When I say racers, I mean only the people on the boat during the race. Coaches, builders, managers etc. could be of any country of orgin to promote countries like China and others to participate and have a chance. I think materials can come from anycountry but construction should take place in the country of orgin. As for the boats I like the current run what you brung format and lets see who wins.
