2013 America's Cup. The 34th America's Cup was a series of boat
races held on San Francisco Bay between the defender Oracle Team USA representing the Golden Gate Yacht Club, and the challenger Emirates Team New Zealand representing the Royal New Zealand Yacht Squadron. Team New Zealand won the right to challenge for the cup by winning the 2013 Louis Vuitton Cup
. The 34th America's Cup was the longest ever cup by both number of days and races, and the first since the 25th America's Cup
to feature a winner-take-all final race.
Two new classes of boat were announced. AC72 wing-sail catamarans
are being used for the America's Cup races and the AC45
class, a scaled-down one-design version of the AC72, was used for the preliminary training and racing until boats built to the AC72 rules became available. The amended AC72 Class Rule version 1.1 was published on February 22, 2011.
The AC72 can reach speeds averaging about 30 knots (56 km/h; 35 mph) with peaks over 40 knots (74 km/h; 46 mph); that speed can be as much as 1.8 to slightly over 2.0 times the actual wind speed.
This is significantly faster than the previous ACC boats that reached speeds of 11 to 13 knots (20 to 24 km/h; 13 to 15 mph)
