With the recent AC45 test period proving a success, the AC45 was confirmed for use in all America’s Cup World Series events leading into the 2013 racing season.

“The AC45s are ticking off all the boxes for a great event package,” said Iain Murray, America’s Cup Race Management CEO and Regatta Director, following the close of the Competitor Forum yesterday. “The sailors have found these cats to be fast and fun to race. They are challenging, they are exciting, and when the best sailors in the world get their hands on them, they produce close, tight racing.”

Using the AC45 in all AC World Series events instead of switching to the AC72 in season two was one of several changes voted on by America’s Cup competitors on Tuesday 31 May. This move also provides teams with another opportunity to manage competition costs.

“After we put the AC45 through its paces in New Zealand, we knew we had the right boat for the next era of America’s Cup sailing,” Murray said. “By making the AC45 the boat of the AC World Series, logistics and overhead can be dramatically reduced at the outset of the 34th America’s Cup cycle. This is a great benefit for all of our teams, providing them with more time in the commercial marketplace and less of a cash investment up front.”

The larger AC72 will now appear on the water from July 2012. Teams will work up their AC72’s and race the AC World Series leading into the Louis Vuitton Cup, America’s Cup Challenger Series, and the 34th America’s Cup Finals in San Francisco. The extended time-period for the debut of the AC72 allows teams more time for development of the boat.

The race format and scoring for the 2011 AC World Series have also been released. The format will include a combination of Fleet and Match Racing with winners for each as well as an overall winner that will be determined on the final Sunday of the regatta. The AC World Series starts 6 August in Cascais, Portugal.

Other updates agreed by the Competitors include:

1. Teams to launch AC72s starting 1 July 2012 (there is a limited exception to launch and sail earlier for any proven pre-existing contractual obligations)
2. Teams have the same limited number of testing days in the AC72s in advance of racing
3. The first Performance Bond for the AC World Series is eliminated and replaced with an Entry Fee ($100,000 USD)
4. Updated late entry procedure – teams can enter late at discretion of the Defender
5. Competitors must sign an AC45 purchase contract with a 50 percent non-refundable deposit paid by 10 June
6. Teams will consolidate their websites into www.americascup.com by 1 July 2011

A press conference will be held in San Francisco on 15 June to introduce the teams and discuss the updated program for the 34th America’s Cup.
