This great video comes via Tom Ehman, who was in Copenhagen over the weekend. He received the link from Johan Granath (www.persept.se), who happened to shoot BMW ORACLE Racing screaming downwind on Saturday, when racing was cancelled because of too much breeze.
Skipper Larry Ellison said they hit 25 knots before racing was called off and they returned, reluctantly by all accounts, to port. Maybe you don't need a trimaran to sail fast...
