I am digging the America’s Cup races so far. But one thing that perplexes me is how far out of the water these catamarans ride. (That, and their astonishing speed.)

Held on the sea by the physics that I don't properly understand: Oracle Team USA and Emirates Team New Zealand racing in San Francisco today. Wow.

At one point in one of today’s races, the Team NZ boat made a turn (tack? sorry, I’m not up on the nautical terms) and  to me, it looked like there was not a lot holding it on the sea! Crikey! Talk about bleeding edge technology.

Very impressive.
