AC72 : Development and Testing
The
AC72:
The AC72 is a 72-foot catamaran with
a wingsail. These are the boats which will be
used in the 34th Defense of the America's Cup in 2013,
and in the Louis
Vuitton Cup regatta which selects the Challenger for
the America's Cup.

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.

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, and 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. Boat #2:

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.
