you're right Ginola, I was intrigued so did a bit of digging. It wasn't the America's Cup as in the event that's just happened in SF though.
It was what they called the "America's Cup World Series" and was basically a regatta of many teams/boats that competed under the latest regulations of the sport, ie the most modern and fastest boats to have graced these shores under competition, if I gather correctly as some sort of precursor to the real event.
