Lunna Rossa makes a move:
* America's Cup challenger Team Luna Rossa has announced that for their
AC72 crew, Chris Draper has been chosen as helmsman and Francesco Bruni
will be the tactician. At the upcoming America's Cup World Series event in
Naples, Italy in April, Draper will helm one of the Luna Rossa AC45s, with
Bruni driving the other. -- Full story: http://tinyurl.com/LR-021813
Here is a very fun article describing a ride on ETNZ's latest monster. Barker says "We are going to go over 40k today"
There is video at the end of the link below that show #2 ETNZ foiling downwind. There is also a mention of boat #1 hitting 48k!
New Zealand Herald reporter Dana Johannsen hitches a ride on Team NZ's new
AC72 as it tests on the Hauraki Gulf.
It wasn't being made to sign a waiver before I hopped on board Team New
Zealand's new AC72 that made me nervous - apparently the team's legal
department are kept busy enough as it is.
Nor was it being handed a helmet and an oxygen bottle to strap around my
waist in case the super-sized racing machine should capsize and I get
trapped under water.
It was hearing skipper Dean Barker briefing on the on-board comms before
the start of the day's testing that he hoped to push the boat upwards of 40
knots - around 75km/h - on just its third day on the water and second
proper sailing day.
Looking at the faces of the design team on the chase boat, they too were a
bit uneasy about the skipper's plans.
But with the big event in San Francisco on the horizon, the sense of
urgency in the Team New Zealand camp has been ratcheted up several notches
since the launch of their second boat, New Zealand Aotearoa.
So as I gingerly climb aboard NZL05, I knew this was going to be no
pleasure cruise around the Hauraki Gulf.
Moving around the boat takes some getting used to. As I stagger about on
the netting like a new-born foal, clambering from one side to the other
whenever a tack is performed, the crew sprint past me, easily traversing
the distance between the two hulls in a couple of bounds.
I'm seated in the driest spot on the boat, right in the centre, but that
does not save me from the odd dousing.
It is the windward crew that are most in the firing line, though, with
Richard Meachem, the team's bowman, hunkering down to avoid the massive
shower of spray as the windward foil kisses the water.
Today is considered a calm day, with a flat sea and moderate winds, but
full wet-weather gear is a must.
The real ride begins when they head downwind.
During the testing of their first boat late last year, I watched in awe
from a chase boat as the giant catamaran with the same dimensions as a
tennis court (well, 3m wider, to be exact) flew above the water. It is
quite another thing to be on board experiencing lift-off for the first
time. -- Read on: http://tinyurl.com/ETNZ-021813
Oracle flies! See the video of the Black Beauty ripping it UP around San Francisco Bay. Artemis is shown too as they mess about. The new foils seem to be very steady but do they allow a deep enough angle off the wind? Rumor has it the new ETNZ boat (#2) is not a foiler.

Oracle Team USA (USA), Defender -
Oracle Team USA relaunched their AC72 on Feb. 4. The first two days were
spent commissioning the repaired yacht and running it through various load
tests out on the San Francisco Bay. "We treated today kind of like we had a
new boat, so it was basically a sea trial," said tactician John Kostecki
after the first day back.
The hulls and platform were repaired and modifications completed on
schedule at the team base at Pier 80. The new wing was built in New Zealand
at Core Builders Composites and assembled at the base in San Francisco.
Among the modifications is a new steering system in place of a tiller. Also
as General Manager Grant Simmer said, "You'll see the boat has different
centerboards in it - that's an ongoing research project. We're not sure
where we'll end up, but this is the next stage in our development."
Oracle Team USA plans to sail the AC72 several days each week. Work also
continues on the build of the team's second AC72.

Artemis Racing (SWE), Challenger of Record -
Artemis Racing continues to chase as much AC72 sailing as possible. Sailing
with our second wing since mid January, we are continually gathering data
to improve performance. We anticipate lining up with Oracle during
February, which will be very interesting. When not AC72 sailing, the team
is match-racing its two AC 45s.
The Red Bull Youth America's Cup selection trials are happening Feb 9-24
here on San Francisco Bay. Björn Johansson, coach at the Royal Swedish
Yacht Club, helmsman Charlie Ekberg and tactician Niclas Düring from
Swedish Youth Challenge will be here to check out the competition.
As Artemis Racing is fielding a team in the Red Bull Youth America's Cup it
does not need to participate in the selection trial to qualify. While in
town, Björn, Charlie, and Niclas will spend some time with Artemis Racing
around the facilities in Alameda, sail on the AC45's and watch the team
train on the AC72.
Emirates Team New Zealand (NZL), Challenger -
Five months from the start of the Louis Vuitton Cup. Emirates Team New
Zealand's second AC72 is in the shed, for a few final tweaks from the
engineers and systems experts before going sailing.
Boat 2 was blessed on February 4, a blustery, damp Monday. With a steady 25
knots at the top of the wing the boat was never going to be lifted into the
Thursday of this week was to have been the first sailing day but it's like
a mill pond on the Hauraki Gulf. The team is now having four days off,
starting Friday. As team boss Grant Dalton has said, the time off is small
reward for a team that has worked crazy hours for the past few months.
With the pressure off, the team's schedule was revised to give shore crew
time to tie down the loose ends now and lessen the risk of downtime when
the testing and training programme gets underway early next week.
February will be a busy month. The sailing programme will be intense. The
clock's ticking and the team is very mindful of the fact that it has to
pack-up the base in April and move the entire operation to San Francisco
while Artemis and Oracle's programmes continue.
Luna Rossa Challenge 2013 (ITA), Challenger -
Luna Rossa moves forward in its training program according to plan. In
addition to technical and sports activities on the AC72, as well as testing
sessions with the SL33, the crew is also race training on its two AC 45
Throughout February the team will be focused on testing and development
projects; on Thursday, February 7th, the AC72 will stop sailing for a week
to undergo modifications and upgrades to both the wing and the platform.
The on-water activities will start again on February 14th, with two days of
sea trials aimed to ensure that all of the modifications function
The team Luna Rossa will then resume racing against Emirates Team New
Zealand, who will be sailing its second and newly-launched AC 72 catamaran.

Jimmy Spithill, Oracle Team USA helm: "We tried to sail with each other
before this but it never worked out. We're both really open and honest with
each other and don't get offended - that's the key. We need to have a
relationship where we can be critical or ask questions of one another and
not take it personally. We both know the only reason we're questioning
something is we want to get better, to learn. Plus we both want to win. We
also have similar personal interests - we both enjoy sports, we have kids
similar ages - which is also important, and helps makes it work."
John Kostecki, Oracle Team USA tactician: "After the 2007 Cup, we were both
being recruited by Russell Coutts, and I contacted Jimmy to see where he
was at and try to team up with him. We've been sailing together for quite
some time now. And, we've also been working really hard on communication
and teamwork. Jimmy is not only a great helmsman, but also a capable
tactician. I come from a helmsman background, so I think we have a good
Ray Davies, Emirates Team New Zealand tactician: "We didn't actually start
the helm-tactician team until after the 2007 America's Cup. We started with
the Louis Vuitton World Series at Auckland. We came from being behind in
the finals and came back to win the series so that was a great introduction
and we've done a lot of regattas since then. We had sailed together a lot
prior to that. During the last Cup I was the strategist, Dean on helm.
"The more you sail, the more you pick up - you keep learning about each
other and its fantastic to have a few years under the belt because you do
read the situations by the tone of their voice, picking up more than just a
few words in the conversation. It's been very valuable to have that
experience and time together now, and we keep learning each time we go out
about the other operates. That has become very important with the AC72.
Everything has to be running smoothly and right now it feels like it's all
going well." -- Read on:

Something seems amiss. What am I missing that allows Russell Coutts to say the following? Count Ferrari is going on record to say the ETNZ is the favorite, at this time, to win the LV Cup and face off with Oracle in the AC.
Russell Coutts, CEO of America's Cup defender Oracle Team USA, doesn't
expect to be confronting the Kiwis when the 34th Match is contested in
September. "We haven't yet seen the second boat of Artemis and I wouldn't
write Artemis off right now. It looks to me they will come out strong with
the changes they recently made in their organisation. I, certainly, am not
thinking we will be facing Team New Zealand." --
ARTEMIS FLIES WING TWO
San Francisco, CA (January 24, 2013) - Artemis Racing trained with its
second wing sail for the first time this week. Principal Designer Juan
Kouyoumojian calls the new wing an evolution from wing one. “The general
concept is much the same: I would define it as a refinement of the first
wing. It’s not fundamentally different,” he said.
Kouyoumojian continued, “Two years ago we were a brand new team, we didn’t
have people, we didn’t have facilities, we didn’t have people who had worked
together. We started building the first wing early because it was a good way
to kick-start the team. When you get down to the second boat having had the
experience of the first build and having people who have learned how to work
together, then things are a lot easier. The second wing became a much more
normal and much easier wing to build and set up. That’s why we’ve made it on
schedule and on weight, which is as it should be.”
Team CEO Paul Cayard was happy with the first sail on wing two, citing just
small adjustments that they will make.
“We operated the wing with all of its controls and it all functions well. We
had up to 16 knots of wind, which was a bit more than we needed for the
first sail, but everything was fine and it was a productive day. They take
many months to build and we were pretty on schedule. These things are such
custom items and there’s not a single thing that’s off the shelf here so I
think the guys did a fantastic job.” -- Details at:

An article with an interview of a catamaran designer that went out on his own after being with Artemis. It gets technical but have fun with it.
Interview here, Gonzaldo Renando
LOOKING UNDER THE HOOD
Sail-World caught up with Mike Drummond, who recently left the Oracle
Racing design team, for his impression of the four designs currently
working up towards the 2013 America's Cup regatta.
"From the design point of view there are three and a half groups," he
counters. "Emirates Team NZ and Prada look like they have identical hulls
and wingsails, but with different foils.
"Overall I think Emirates Team NZ has a good, straight forward,
conservative boat with lots of volume, and a well proven structural
arrangement. The wingsail is straight out of a C-class evolution. They have
correctly focused on foil over wing development.
"Although they have added fairings, it looks like Emirates Team NZ still
have a high windage platform - with their centre spine and rigging and so
forth. That is not critical at this stage, but it's a safe assumption their
second boat will be similar, so there is a limit to the amount of drag
reduction they can achieve.
"The flip side is they've had a good robust package where they have been
able to go sailing from Day 1 and learn about this new class of yacht which
they can then feed into their second boat eventually.
"These boats are very high speed and high on apparent windspeeds. Their
windage as a proportion of their total drag is much higher than in
monohulls and so it needs to be a higher priority in the design."
He expands to say that the windage issue is not just turbulence around the
rigging and the platform (multihull-speak for the combination of hulls,
beams and decking) but also relates to aerodynamic efficiency. There is a
very large gap between the Emirates Team NZ wing and the surface of the
water (which Oracle Team USA have resolved somewhat with their central pod
structure which forms an 'extension' to their wingsail and improves the
effective span below the platform.)
"In light airs that drag and inefficiency is very large - of the order of
5% compared with a perfect seal - which is close to 5% of boat speed. The
drag percentage reduces in strong winds but there is still a gap," he adds.
Hence Oracle's solution with a centre pod doing double duty as a structural
member and forming a solid aero barrier, together with a horizontal deck
surface. The effect is that Oracle is able to carry the lift from the
wingsail much closer to the water surface. Beyond that Drummond wouldn't
discuss further specifics of the pod or how it was designed to work. --

ARRIVEDERCI: "The 34th America's Cup will be the only one in which we will
see these (AC72) catamarans. The question is not what is more just: for the
America's Cup to be in multihulls or monohulls. Catamarans are attractive.
It is that the AC72 is a folly to put it in water. It takes 40 people each
time. The America's Cup must not only be popular, but also accessible." -
Patrizio Bertelli, owner of Luna Rossa, America's Cup challenger,
QUOTE / UNQUOTE
"We're in the final stretch now. It's all about time on the water and
gluing the team together. The design is done. We've made our choices. There
is fine-tuning here and there but now it's about getting the sailing team
working to make the best of what we have. I think for me, we are thinking
long term in building this team. It's been two or three years now and
whatever happens, we have a great team and good base to continue. It will
be up to the next defender to decide the rules so it's not entirely in our
control whether we participate or not, but yes, we do it see it long term."

Date: 1-11-13 A run down on what is going on with the 4 AC72 teams.
THE YEAR OF THE AMERICA'S CUP IS UPON US
Scuttlebutt will be providing a monthly summary for each of the four teams
through to the Louis Vuitton Cup (July 4-Sept 1) and the 34th Match (Sept
7-22). All the teams returned this week from holiday break... here's what
they are up to in January:
* Oracle Team USA (USA), Defender -
The team returned from a holiday break to greet the arrival of wing 2.
Constructed at Core Builders Composites in New Zealand, the wing was
shipped to San Francisco, arrived Jan. 8, and will be assembled and tested
over the coming weeks.
Work continues on the first AC72 following its capsize in October.
Composite work was completed and the platform reassembled prior to
Christmas. Now, the shore team begins installing systems - hydraulics,
winch systems, nets, etc. The goal is to sail the AC72 again in early
February. All is happening concurrently with the build of the second boat
and third wing which are expected in the spring. The team ultimately plans
for two-boat testing and training this summer.
This month, the sailing team resumes the AC45 training and testing program,
as well as preparing to sail the AC72. Several members of the team also
continue working with the two squads selected by Oracle Team USA to compete
in the Red Bull Youth America's Cup.
* Artemis Racing (SWE), Challenger of Record -
The team returns from the Christmas break recharged and ready to continue
preparing for the 34th America's Cup. The Artemis team will continue to
train on the AC72 on San Francisco Bay. On days that the AC72 doesn't sail,
Iain Percy and the sailing team train in our fleet of Moths, A-Cats, F18s
and AC45s out of our base in Alameda, CA.
The teams' second wing and second boat are well under way, with the plan to
sail with the second wing in February. Boat 2 will be complete in April;
the team does not plan on training with both boats at the same time.
This week helm Nathan Outteridge is competing in the 2013 Australian Moth
Nationals, fine tuning his foiling skills. Team Founder Torbjorn Tornqvist
begins competition again on the RC 44 tour with the first event of the
season in Oman, January 30-Feb 3.
* Emirates Team New Zealand (NZL), Challenger -
The team takes delivery of its second AC72 next week. Boat 1 was
decommissioned before Christmas, with some of the parts - winch drums and
hydraulic fittings for example - to be installed in the second boat.
The shore crew, most of the sailing team, and contractors will be working
on fit-out through January and into February: electronics, hydraulics, the
trampoline and all the hundreds of small fittings will be put on to the
boat in preparation for the low-key launch.
The sailing team is also planning to do some sailing during January. The
team's AC45 has been commissioned over the break and there has been talk of
some race practice with Luna Rossa.
Construction of the team's second wing is well advanced although it will
not be seen in public until later. Boat 2 will use the first wing for a few
weeks to allow the team to test the platform's structural integrity and
systems and not have any potential issues with a new wing intervene in the
* Luna Rossa Challenge 2013 (ITA), Challenger -
The plan for January is to make the most of the 13 remaining days allowed
by the Protocol to sail the AC72 prior to the January 31st deadline. This
is the only boat the team plans to build.
This coming week the team will be concentrating on match racing practice
sessions with its two AC45 catamarans Luna Rossa Swordfish and Luna Rossa
Piranha. At the same time an additional group of sailors will be training
on the SL33 catamaran to practice foiling techniques.
Starting from next week the crew will resume training on the Luna Rossa
AC72 catamaran. The main goals for this first period will be a mix of crew
training sessions around the course and speed tests. The training work on
the AC72 will be alternated in the coming weeks with practice on the AC45
boats and on the SL33.
Date: 1-7-13 (the AC45 circuit will not get the focus it has enjoyed)
* (December 29, 2012) - The International Jury for the 34th America's Cup
has deducted five sailing days from Oracle Team USA as the final decision
in the espionage case brought against the defender by Italian syndicate
Luna Rossa Challenge 2013. The International Jury determined that Oracle
Team USA had breached part of the Protocol by being within 200 meters of
the Italian AC72 during a training session in New Zealand in early
November. Oracle Team USA has returned 10 photos as instructed and was also
fined approximately $15,200. Details:http://tinyurl.com/ACUP-010113

New Zealand. -- Full report: http://tinyurl.com/Stuff-
Also, note that the A-team for ETNZ will not be going to the ACWS events as they think that will take away from their working the AC 72 to the max. They, will, "if they have to" send in a youth team to compete to the two Italian venues and the New York venue if that works out.

OUT WITH THE (NOT VERY) OLD, IN WITH THE NEW
(December 12, 2012) - Emirates Team New Zealand completed the permitted 30
days of testing and training in its first AC72 catamaran, and now will put
the boat out to pasture. Rules for the 34th America's Cup allowed only 30
sailing days for the first boat between July 2012 and the end of January
The shore crew will start on Thursday to decommission the yacht while the
team concentrates on finishing Boat 2. Winch drums and some hardware will
be removed from the yacht and fitted to second boat, while the first boat
is refitted in the near future and held in reserve, to be commissioned
quickly in the event it's needed.
Components for the new boat are being built at Auckland companies Cookson
Boats and Southern Spars. The second wing is being assembled now at the
team's Viaduct Harbour base. Hulls, beams and other parts of the platform
will be delivered to the base early in January for a launch in early
On why the team will not train with both boats, Managing director Grant
Dalton explained that it was not possible. "We never considered sailing
both boats together because of the logistics and cost involved.
"It takes 35 people 1½ hours to launch the AC72. Three hours out of morning
to launch two 72s and three hours at the other end of the day to retrieve
them is out of the question. The only solution would to have two separate
operations to launch, retrieve, maintain and improve two AC72s and that is
not a realistic prospect for Emirates Team New Zealand."
Dalton said the team would gain many of the benefits by racing with another
boat through the arrangement with Luna Rossa. -- http://etnzblog.com/
HARNESSING THE BEAST
With the cloud of death and destruction now hovering over the America's Cup
and the exceedingly powerful AC72, let's assume for a moment the sailors
will soon tame this beast of a boat. But for the four competing teams,
their mission is complicated by the schedule. Taming won't be enough; they
must have it fully trained.
The Louis Vuitton challenger series is in July and August, otherwise known
as the "season of nuclear winds". For the challenging team lucky enough to
win (or survive), they will advance to the more moderate winds of September
for the Match. But the defender is not much better off; they will be
training during 'nuclear' season.
Given the difference in San Francisco Bay wind strength from July through
to September, can the same design work effectively in both realms?
"I think the challengers and the defender will need to think about
developing boats that work well through the range of windspeeds,"
anticipates Pete Melvin, who is a member of the New Zealand design team.
"Average wind speed will be higher in the July-August period, but you can
still get windy days in September.
Since the protocol does state how competitors may substitute yachts between
the Louis Vuitton Cup and the America's Cup Match, or between different
stages of each series, this could lead to the development of specific modes
for the conditions.
"There is considerable debate as to how many measurement certificates will
be allowed during a series, and the outcome of that debate will have a
direct impact on how diverse your quiver of equipment will need to be,"
noted Melvin. "The AC72 Class Rule only allows one certificate at a time.
"The AC72 Class Rule also stipulates that you can only measure in one set
of hulls, daggerboards, and wing on a certificate. This was done to reduce
cost and complexity, and to promote the development of all-around gear
rather than condition-specific gear.
"For both the LVC and the Match, the current proposal is to allow boats to
have multiple pre-measured certificates. You would need to notify the
measurement committee the evening before if you were going to change your
configuration to a different certificate."
Time will tell if configuration changes become the result of performance
decisions or death and destruction. --

From Scuttlebutt 3700:
AC72 CAPSIZES: RISKS AND PREPARATION
Safety issues with the Americas Cup radical new 72-foot-long catamarans
have been a hot topic since the design was unveiled. Capsizing wasn't an
"if" but a "when" -- and "when" arrived on Tuesday, when Oracle Team USA
pitchpoled in 30 knots of wind near San Francisco's Golden Gate Bridge.
Dirk Kramers, Oracle Team USA's engineering guru, and Iain Murray, Americas
Cup Regatta Management Director, recently addressed the risk issues
inherent in the boat's design and how best to manage the aftermath of
flipping one of these huge race yachts.
2013 will make the fifth Cup cycle for Kramers, who was one of the
multihull expert behind the Stars&Stripes 88 and Alinghi 5, as well as the
Alinghi and Young America monohull campaigns. His experience with the
America's Cup is one of the most extensive of any active player. Kramers
believes that the safety systems designed into USA-17 are fairly
self-explanatory personal safety equipment, rescue personnel, righting
lines -- but noted that many safety systems would not really see active
practice. At least not planned practice. Post-Tuesday, that may be a
"There are a lot of different safety aspects, most of which are common
sense, like wearing life preservers and helmets", said Kramers on a recent
tour of the team's Pier 80 base. "It's also important to always have a
knife on you in case you get stuck or caught somewhere, like a diver you
can cut yourself free."
"The boat is set up with righting lines, in case we have to right the boat.
We also have buddy-breather cartridges, so if you have to dive, you can go
under longer. But it's also an organizational issue; we have three to four
boats out there supporting us, and there's a whole set of response
maneuvers that we've practiced to make sure that we do the right thing at
the right time. For example, if someone falls off and gets hurt, that's the
first priority. The next priority is getting the boat head-to-wind. So
there's a whole series of events that have different response maneuvers."
Oracle went with a design that includes a large pod below the boat's hard
wing that acts as something of a wing extension, providing more power
closer to the waterline. That's a positive contribution, but one negative
with the pod is it means the sailors cannot do the "monkey dance" down the
netting to safety.
"One of the aspects that's difficult about this kind of boat is that once
it's capsized, you can't really climb up or climb down. So you're sort of
stuck. With the AC45, you can climb up and down, but this boat has the big
pod in the middle. And you can imagine falling off, if the boat is at 90
degrees. If you fall down into something hard, that's not going to be good.
We've had a lot of guys falling off the AC45s, but we've been lucky that no
one has hit something hard yet -- like what happened to Russell, it was
inches away from it being a big problem. And it's happened to other guys.
That is the biggest thing, making sure the guys have something to hang
onto." -- CupInfo, read on:
READ THE INSTRUCTION MANUAL
Despite watching the teams at the America's Cup World Series become
increasingly proficient at surviving an AC 45 capsize, it was well
understood that an AC 72 capsize would be much worse. The narrow line
between control and catastrophe would be given a wide berth.
But on October 16 the line got crossed. America's Cup defender Oracle Team
USA capsized their AC 72 on the team's eighth day of training on the boat,
digging their bows in for a pitch-pole while bearing away downwind. "I
guess we found our limit today," admitted tactician Tom Slingsby.
With training days limited by the rules, and with the defender already
behind schedule due to daggerboard problems, Oracle Team USA was in
catch-up mode. What made matters worse, Emirates Team New Zealand appeared
to be progressing quickly with the development of their AC 72. And with the
light winds of fall and winter soon to descend on San Francisco Bay, the
defender needed hours on the water.
The forecast for San Francisco Bay on Tuesday was for a maximum of 18
knots; certainly within the range of safety. But when winds spiked to 30
knots, the defender was caught using one of their limited training days in
Witnesses say the team appeared to be wisely cautious, using only the small
headsail and keeping the hulls in the water rather than foiling. The
defender had previously demonstrated their foiling ability, but had yet to
exhibit the same foiling control as the Kiwis. And with a strong ebb
pushing against winds estimated to be in the mid-20s, maintaining control
in the steep chop at this early stage of training was prudent.
But herein, quite possibly, lied the onboard conflict. Observers have noted
that the defender's AC 72 opted for a narrow bow shape design, which is
good for reducing weight and windage but does not prevent a pitch-pole like
a fuller shape. So how did the designers expect their AC 72 to avoid
pitch-poling in strong winds?
As team engineer Dirk Kramers explains, their AC 72 is supposed to be
foiling when they bear away. "Our hull is quite small, much smaller than
Team New Zealand's, so we are reliant on the foils to keep it from
pitchpoling in a bearaway," explained Kramers.
Memo to spectators... get good seats at the upwind mark.
UPDATE: The San Francisco Bay current, which swept the AC 72 four miles
west of the Golden Gate Bridge, was estimated to be over five knots. The
boat, which capsized at 3:00 pm Tuesday, was upside down when it finally
returned to the team's Pier 80 base by 1:00 am Wednesday. The wing,
estimated to cost $2 million, was completely destroyed. A replacement wing,
according to Jeremy Leonard of Sail Revolution, may not be ready until
after Christmas. The port hull, which had filled with water, was supported
by airbags as it was pumped. The platform was eventually hauled, with no
disclosure at press time regarding damage.

*)The first thing noticed on this cat was the center pod with all the grinding stations on one platform. A compromise as are all boats. With the grinders in the center pod (for lack of a better descriptor) there is less travel for the crew, however their weight will not be on the weather rail as far leveraged as the other designs currently sailing. They will only be carrying about 1/2 of the grinding equipment making it lighter overall, maybe... Lots of thoughts still to be processed.
*)A teaser video showing the 'Batzilla' (the name being bantered about, I like it, for the Oracle AC72) being launched and the foils just showing. Apparently the dagger board broke during the first day (of 30 days allowed prior to official competition.). No word on whether it was the foil that failed.
There is a Batman decal on the inside of one of the hulls.

There was a gear failure but that was not covered specifically. The boat has the center hull for a design change over ETNZ or Artemis.

Artemis: (Challenger of Record)
Finally, good news.
FINALLY... ALL SYSTEMS GO
(November 3, 2012) - The America's Cup Challenger of Record, Artemis Racing
(SWE), is ready for some good luck. They destroyed their wing in May, which
has delayed their training schedule on their AC72. And when the wing was
ready to go, their AC72 platform incurred damage during structural testing
last month. But on Saturday, it was... finally... all systems go.
It was a long tiresome day for the Artemis team, one which began before
dawn. The hull moved to waters edge in the darkness and loaded via crane
slowly as the sun began to rise. By noon, the wing was attached to the hull
for the first time and the shore crew and tech team assured all was well
for the Christening ceremony.
It was a brief, diligent affair with member of the Artemis Team in
attendance, many children running about as parents kept a watchful eye. The
would be no smashing of a champagne bottle, no sir, after what has
transpired in recent weeks, shaking the bottle and spritzing the starboard
hull would suffice just fine, thank you very much!
The crew will be testing the functions of all the operating system with a
fine tooth comb before the big red machine takes her first sail on San
Francisco Bay...hopefully next week. But with weather systems headed
towards the Northern California area by mid week, the hope would be sooner
rather than later. -- Pressure Drop, photos: http://tinyurl.com/PD-110412

MORE BAD NEWS: Challenger of record Artemis Racing, which has yet to sail
their AC 72, will have to wait a little longer. Their wing, which was
damaged in May during testing on another boat, is now ready but their AC 72
apparently is not. Today (Oct. 18) the team damaged the front beam while
conducting structural tests in San Francisco. The AC72 has been hauled out
of the water and the design team, led by Principal Designer Juan
Kouyoumidjian, is on site to evaluate the damage. --

Emirates Team New Zealand (ETNZ):
Go to team ETNZ for a look at this fabulous Gladwell article from 11-16-12 in Butt.
From Scuttlebutt (www.sailingscuttlebutt.com)
IF THE AMERICA'S CUP WAS RACED TODAY....
On the Catamaran Racing, News & Design website, images of the U.S., Sweden,
and New Zealand-Italy AC72 designs have been posted with editorial
As a reference it gives an idea of the different concepts used. Needless to
say ETNZ-Luna Rossa is the best hull-platform in my view. Artemis is not a
flying AC72; it is only assisted by curved daggers. Not even T rudders at
The front beam position is quite extreme although the wing support vertex
is a little backwards due to the V shape of the beam. The concept behind
this is to gain structural benefits on the forward beam position, and the
ability to have a better range for wing trimming/rake to backwards, thus
compensating that forward load.
To avoid pitching or to maintain the bow up on this configuration, they
totally rely on the daggers lift. But we already saw what happened to that
concept in Oracle. Let's wait to see her sail, but I'm glad (Loick) Peyron
will be there helming at least in the initial tests. So Artemis played safe
on the flying area, but went quite extreme on the front beam and hull.
After confirming that Oracle was going down in the bearaways, I have strong
doubts that this incredible piece of machinery (Artemis) will work any
different in the same situation or maybe their dagger lift configuration
will prevent it.
It is easy now to choose an option; I would have go ETNZ platform with
Artemis conservative non-foiling solution. Clearly the most 'standard' &
safe solution for San Francisco conditions. I still don´t get why designers
are going for extra foiling lift plus less aero/hydro drag to the extreme,
risking the whole project when you are going to race in +20 knots. Someone
would quickly answer: "Cause we want a design edge to win the Cup."
The only issue is that they are working in unknown terrain for these kinds
of beasts on the worst venue possible for a first try, and a rock solid
bullet proof design right now would have won easily, as we don´t know if
any of these extreme boats will end a single race in +20 knots!
See photos: http://www.catsailingnews.com/
COMMENT: The racing period for the successful challenger in 2013 is two and
a half months, most of which is occurring in the +20 knot range, while the
defender need only survive for two weeks in more moderate conditions.
Either the challenger will be battle tested and formidable, or battle weary
and fatigued. - Craig Leweck, Scuttlebutt
QUOTE / UNQUOTE
"Our boat, in terms of windage, is far from complete. All the fairings are
still to come. The boat will look significantly different in race mode. One
of the issues with putting all the fairings on the boat is that it makes a
lot of the systems difficult to get at and tune, so we chose to put the
boat in the water in a raw state to facilitate that development process."
-- Emirates Team New Zealand technical director Nick Holroyd,
The latest (11-16-12) article from Gladwell at Sailing World has photos and a description of a sail in NZ in 25k winds. This team is kicking ass now. Read all about it.
After 16 days of water testing the new boat, including many foiling experiences, ETNZ is taking the boat back into the shop for modifications. This was announced Nov. 2, in www.sailingscuttlebutt.com.
There are a lot of design issues involved with this new type of AC race boat. Team ETNZ has launched the first of this type of boat. They are allowed only so many build efforts (depending on which part of the boat is being built) and so many days of actual on the water testing. This is part of the money limiting that was written into the AC protocol for this go round to try and attract more teams.
There are five teams building AC 72s. Oracle (the defender) is building two boats. Artemis (Sweden) is building two? maybe. Team Korea is to build soon and the last to enter the fray is Team Lunna Rossa (Italy) who is expected to build two boats also.
Auckland, NZ is where you can go to see these new water missles launched and training done as Lunna Rossa has entered into a training agreement with Team ETNZ.
Oracle and Lunna Rossa are shadowing the first day of sailing for the ETZ boat. Check the story here.

The AC racing will be in San Francisco starting with challenger series in the Louis Vuitton Cup in the later part of the summer in 2013.

A DAY IN THE LIFE OF...
Rod Davis, coach for the America's Cup challenger Emirates Team New
Zealand, provides some answer to a question he's often asked ... "what do
you do out there all day?"
When Emirates Team New Zealand goes sailing on the AC72, people might think
we just rip around all day up on foils, trying to set a new speed record or
outrun our poor, and very faithful, chase boat drivers.
We don't, well not any more. We did for a little while, but we needed to
get on with a programme to win the America's Cup. There is no typical day
when we're sailing the big cat. Each time we go out, we chip away at the
huge list of things we need to learn.
Here's a very brief precis of the other day's programme:
Wing in at 6:30, boat in the water at 7:00, off the dock 8:30 (after boat
checks). Forecast was for 10-12 knots of wind.
First on the "to learn" list: check a new number two jib, a development of
an earlier sail. Jibs are numbered just like any other boat, one being the
biggest and four being the smallest. I'm not sure of the logic there.
Next sail on the list was the new second-generation "Code Zero". The AC72,
like the AC45, has two downwind sails. A gennaker for lighter winds that
goes way back, overlapping the wing and a code 0 that looks like a
mast-head jib in profile which is used in stronger downwind conditions.
Speed testing followed. Foiling vs non-foiling using all possible settings
to make each configuration work to the maxim of its potential.
The 72 covers a lot of miles in an hour of this kind of work, and we get a
long way from home. The downhill runway is put to good use with up-wind
sailing back into the gulf.
Then it's time for some pre-starts. From our experience with the AC45 we
know there is a lot on in the pre-start... deploy the gennaker for the
entry, furl it for the dial up (that seems to happen more often than not)
then head to wind, bear off, another gennaker deploy and furl in the gybe,
for the final run to the start line with the all-important time on distance
All of the above happens in just two minutes. It's an understatement to say
we've got a lot on.
Back at the dock, the boat is lifted from the water and packed away. After
debriefing the day on what we learned and how to do it better next time
some of us get out of the office by 6pm.
And the next day we have the same timing with a wing lift at 6:30 am...
forever chipping away on the to-learn list.

Team Lunna Rossa:
* America's Cup challenger Team Luna Rossa plans to launch for the first
time their AC 72 on October 26th in Auckland, New Zealand, where the team
is currently finalizing the assembly. The team will continue to train
throughout the Austral summer before relocating to San Francisco next year
in anticipation for the Louis Vuitton Cup which begins in July. --
This could put them in the game with the two of the 4 teams broken. Only ETNZ with a working 72 at the moment.
I have seen nothing so far on this team except the intention to train in Auckland and share data with Team ETNZ.

Max Sirena said everybody had seen
the Extreme 40s crash and burn. “These
AC72 yachts are 100 times more powerful.
They will be dangerous boats to sail.
Whereas a Version Five monohull would
take a 5-10 second grind for each tack, the
AC72 would require constant grinds of up
to a minute. Bearing in the mind that the
shape of the recently-published course for
San Francisco is long and narrow, Dalton
estimates that it will take 54 tacks and
gybes to complete a race.
With no part of the course offering
more than three miles in a straight line, the
grinding effort will be virtually non-stop.
Dalton, who said he was training hard to
be part of the crew, said the emphasis on
crew-work and good racing mechanics to
manhandle the boats around the track was
a massive focus for all the teams.
“The crew that can hoist and unfurl their
code zero gennaker two seconds quicker,
will be going away 20 knots faster,” said
Shoebridge. “At those speeds, though,
going past a mark or not being ready for a
manoeuvre will be disastrous.”
Dalton, who was once fined £18,000
for speeding with his giant Club Med
catamaran on Southampton Water, said
the giant wing-catamarans would be
capable of 25 knots upwind and 35-40
