Both America’s Cup teams have taken to the water this week, with the helicopter launch of Alinghi’s catamaran in Lake Geneva, and the first sea trials of BMW Oracle Racing’s modified trimaran, taking place off San Diego.

Alinghi’s catamaran – Alinghi 5 – represents the team’s first steps in its development process towards the 33rd America’s Cup, and the team will now focus on preparing it to sail over the coming weeks. Whether BMW Oracle’s trimaran, known as BOR 90, will be the one to face Alinghi remains to be seen.
