The America's Cup "yacht" racing is well underway in San Francisco Bay. I used quotation marks around "yacht" since these things are yachts or boats in only the broadest sense. Reaching speeds over 50 mph while planing on three hydrofoils, powered by a wing, not a fabric sail, that is the size of a jumbo jet wing, and made almost entirely of carbon fiber, these things are truly awesome.
The New Zealand team has a sizeable lead over the Americans right now (best of 17), but every race is unpredictable and the Kiwis very nearly capsized yesterday.
If you get a chance to watch, the races are on NBCSportsNetwork (NBCSN) at 3:30 or 4PM EST
