America's Cup |
The America's Cup World Series are match races and fleet regattas used as heats for the 2013 America's Cup and the 2017 America's Cup.
The World Series uses AC45 catamarans, a one-design wingsail catamaran designed specifically for the event by Oracle Racing. The AC45 was conceived as a smaller version of the larger AC72 class rule which was used for the 2013 America's Cup. In 2015, the class was modified to AC45F which incorporated hydrofoiling capability for improved performance, with boats achieving peak speeds of 37kt.
The AC45 has the following specifications:
The AC45 are authorized to be taken out of measurement to serve as a testing platform for the America's Cup. Oracle Racing released photographs of an AC45 hydrofoiling with L-type appendages on June 18, 2012, a premonition of Team New Zealand's larger foiling AC72 Aotearoa test boat first spotted in Auckland on August 29, 2012. In February 2015 Oracle Racing and Artemis Racing tested two AC45s modified by Core Builders; They featured L-type hydrofoils, horizontal rudder stabilizers, lengthened crossbeams (herego wide beam), a shortened jib-only bowsprit extending into a centerline pod under the wing, flaring topsides, closed transoms, opened hulls with deep cockpits for binnacles and wheels, replacing the tiller. The authorization does not permit to lengthen the hulls. All other teams carried out similar experiments with the platform.
Nine events were held between 2011 and 2012 in the lead up to the 2013 America's Cup.

In August 2013, the competition jury received a report from Oracle Team USA that their boat and others they had loaned had unauthorized modifications. Since they were using one of these modified boats, the BAR team withdrew from the competition on 7 August 2013. Oracle Team USA withdrew the day after. Penalties imposed included expelling three team members, a $250,000 fine, and a one-point penalty for each of the first two races of the Match in which they would otherwise score a point.
