Yacht design and construction began in 2011, with the first launch permitted in July, 2012, for early testing, and actual racing coming in 2013.  Each team's designers and builders create their own hulls, wings, soft sails, and underwater foils within the confines of the rules, and test and refine their designs as the racing moves forward.  Sailing time was at first limited by the rules.  Track the AC72 sailing days  The first AC72s were limited to 30 sailing days each before January 31, 2013.  Teams may build a second AC72 yacht as their resources allow, launching February 1, 2013 or later, and limited to 45 sailing days until May.  There were no official restrictions after May 1.

Emirates Team New Zealand

The team has built two AC72's. Boat #2 was launched in early February.  Boat #1 will be kept in reserve.  The ETNZ equipment arrived in San Francisco May 8, comprising over 70 shipping containers plus the oversize items, and the team began sailing again May 23 as scheduled.

ETNZ is also partnering with Luna Rossa Challenge to provide engineering and construction resources to help the Italians with their first AC72.  ETNZ revealed their first boat in mid-July, 2012, with an elaborate launching ceremony on July 21.  In late August photos surfaced of the boat on foils, sailing with both hulls out of the water, surprising many, though the other AC72s are now expected to use similar techniques.  After Sailing Day 16 of the initial 30, ETNZ cat #1 was taken to the shop for modifications based on early test results, plus fitting of aerodynamic fairings, emerging again on Nov 13.  On Dec 12, the boat reached its 30th day of testing, and was decommissioned.

Artemis Racing

Artemis Racing debuted their first wingsail months before their boat was completed.  The wing was tested onboard an ORMA trimaran, which is permitted under the rules, in trials off of Valencia, Spain.  Reports were that the mast suffered a major failure related to structural design and not just a simpler component failure.  Artemis investigated the failure extensively.  The boat arrived in San Francisco in August, 2012.  Christening had been planned for mid-October, but the boat was damaged in tow-testing the morning of the ceremony, delaying launch by additional weeks.  The Swedish boat was launched on November 3 with the first sailing day on November 13.  The new Artemis boat was watched closely, with some observers wondering if she was ever intended to foil, though the team eventually confirmed the boat was not designed as a foiler.  In early February on San Francisco Bay, Artemis sailed in the company of Oracle's AC72 for the first time.  Shortly afterward, the team said that they had learned from the match-up and sent the boat into the work shed for modifications, sailing again starting March 22. The team's second boat arrived in San Francisco in early May and was expected to launch soon after.  The team's first boat was extensively damaged in an accident on May 9, killing crew member Andrew Simpson.  The accident delayed the preparation of boat #2, which received modifications including structural reinforcements before launching July 22.  Artemis will miss the Rounds Robin of the Louis Vuitton Cup, but expects to be ready in time for the LVC Semi-Finals.

Oracle Team USA

Oracle has built two boats to defend the America's cup.  Oracle's hulls were built inside the team shed on Pier 80 in San Francisco, joining a number of other components such as cross-beams and the wing sail built in New Zealand by Core Builders.  Wing #1 was raised the last week of August 2013, the hull was launched and tow-tested on San Francisco Bay, the wing stepped to the hull platform later that week, and boat #1 christened "17" with the first sail taking place on August 31.  Two hours into the first sail, though, damage occurred to the daggerboards and related gear.  Oracle adapted temporary daggerboards and the cat was in action again Sept 17th, testing sails.   October 1, the fourth day of sailing, saw the boat foiling, and mid-October the AC72 was back on the water with several modifications, including to the helm.  In its eighth day of sailing, on October 16, the boat capsized in testing on San Francisco Bay.  The crew was reported safe, but the boat had extensive damage, with the wing destroyed.  After repairs to the platform and arrival of the team's second wingsail, 17 was re-launched February 4.  The team's second AC72 was launched April 23, 2013, and had its first official sail on April 24.

Luna Rossa Challenge 2013

Luna Rossa has built a single AC72.  The Italian cat was launched October 26th, 2012, for testing in New Zealand, some of it against ETNZ's first new boat, which was an essentially identical design developed in cooperation.  Luna Rossa was a late entry to the 2013 America's Cup cycle, and contracted with ETNZ to provide design services and construction of key components, which, provided certain restrictions are met, is in keeping with the Protocol rules for this Cup cycle.  Luna Rossa's boat arrived in San Francisco in late April, and originally planned to re-launch on May 10, but external events and weather delayed the Italians' debut on the Bay until May 18.
