I don't agree with you anonymous, neither do the organisers of the last offical America's cup (see [
www.americascup.com]).
Furthermore, if you know a little of the history of the cup, then you must know that it was named "America's cup" after its first winner, a yacht called "America". You cand find details on this history also in the web site I indicated above...I can't believe you never heard this story before!
