The American Youth Sailing Force, a group of young sailors ages 19 to 24 who will represent the U.S. in the Red Bull Youth America's Cup, capsized their 45-foot boat on Sunday. No one was injured and the boat was relatively unharmed after the imposing AC45 catamaran tipped over.

The crew seems blasé about the incident, which to the untrained eye looked pretty damn fun. Watch the boat flop over while the blue-clad sailors scramble like oompah-loompahs to prepare, and enjoy nonchalant commentary by some strapping young maritime enthusiasts.

"The Force" will compete for the Youth America's Cup on September 1-4 in the San Francsico Bay. Don't mess up, boys!
