Pretty sure they did mean "youth" - protocol was written in English!

From Fischers piece at Sail-world, questioning Coutts:
"In addition to the AC World Series there would be a Youth America's Cup from 2012. This would be held in the AC-45 catamarans, and while age limits have yet to be defined, the crew will have to be from the nation of its challenging yacht club."

Speculation is that they intend to set the limit at age 25
