Draft of AC72 rule unveiled
[Source: BMW Oracle] The draft rule for the spectacular AC72 Class went public today.
Encapsulating the 34th America’s Cup – the best sailors in the world on the fastest boats – the AC72 will be a physically demanding boat capable of top speeds twice the windspeed.
The new AC72 class is the first-ever wingsail catamaran class for the America’s Cup and the fastest-ever class in the iconic 159-year-old competition. It replaces the ACC monohull class, which was created in 1988 and first raced in 1992 Cup.
The new boats will make their racing debut in the 2012 season for the America’s Cup World Series ahead of the 34th Match in 2013.
A catamaran was selected as one element to transform and enliven the America’s Cup for the future. A multihull is the ideal dynamic class, capable of being raced hard in winds from 5 to 30 knots to minimize racing delays due to winds too light or too strong.
