America's Cup Boats Use Innovative Design Built for Speed and Power

Posted: September 12, 2013  |  By: Brad Balukjian [LA Times]

The two catamarans zipping across San Francisco Bay in the America's Cup finals each weighs about 163 tons less than America, the winning yacht in 1851 and namesake for sports' oldest active trophy. The lighter load obviously helps these boats achieve speeds up to 50 mph, but there's much more to their design; both are engineering marvels that maximize the energy provided by wind and water.

The AC72 (America's Cup, 72 feet long) catamarans are defending America's Cup champion Oracle Team USA, owned by billionaire Larry Ellison, and challenger Emirates Team New Zealand.

The Kiwis have won four of the first five races and need five more wins to claim the trophy, and Oracle Team USA needs 10 more wins (because of a penalty) to retain the Cup. Racing resumes Thursday.

Unlike the soft sails and single hull used by America and most of the boats in the event's history, the innovative AC72s are built for speed and power.
