34th America's Cup: multihulls!

I think it would only make sense ETNZ wins by a large margin, as they have much more time on the boat. Does LR have a realistic chance in the Louis Vuitton Challenger Series (LVCS) as ETNZ is building a new boat just to be better than that design, and I think ETNZ has a more talented crew. Unless LR just gets really really good with the boat while ETNZ switch boats, I don't think they have too big of a chance if no one breaks anything. And any word on the helmsman for LR? I could see Cammas taking on the job sort of like Peyron with Artemis. (Any word or reason from Hutchinson?)

Also, on the issue of torsion on 17, if they don't make adjustments to change it once it comes back out of the shed, and if boat 2 is no different in that area, I think the designers left it for a very specific reason. I could see 17 coming back out with some sort of rigid rig then having boat 2 remain "loose", or the other way around, and test them against eachother then make the adjustments accordingly to the other boat. But the designers at OR are some of the best, so I wouldn't be surprised is they are doing it for a reason no one else sees.

Steve Clark just backed up what I've been saying since Oracle started sailing:
1) that the "wracking" is probably designed into the Oracle boat-not an unintended consequence.
2) that the platform twist(wracking) could be used to control downforce on the windward rudder.

His quote(see the Oracle thread on SA)-

A little known fact-or at least one that I missed: USA 17 was clocked at 27 knots in a 6 knot wind, according to Foilers!( http://foils.wordpress.com/ )-
thats 4.5 times windspeed!

 

Can the site go english. If so how.

Thanks

What I do is click on a space on the page and a window opens with a translate "tool" listed-click on that and you get a fair translation. I have Vista-don't know how it works on other computers.

Weren't LR and TNZ shipping their 45's back to NZ for training? I thought I read something that said they were.

Did anyone else notice OR ditched the long tiller across the back of 17 after just a few days of testing? If you look in the pictures from the day of the capsize the long tiller is gone and it is just a L shaped beam going back to the rudder on each side.

Also today OR released a video and pictures of 17 being recontructed (see website), and they say the new wing will be in SF after the holidays so one can assume it's on its way now. Do you think they when for a more ambitious wing like Artemis' with different controls to many different areas or stuck with the same design?

 

Australian Dream Team update:

Don Jones has retired. Grant Warrington has named Fred Barrett to guide further updates to Wild Thing (and documentation thereof). Another Australian yacht designer, Joe Adams, was murdered in The Philippines. Scott Jutson, who started his design career in Australia, now lives and designs boats in Vancouver. Paul Larsen now holds the world sailing speed record.

Will someone please whisper in Grant Warrington's ear that he should head up a challenge for the 35th America's Cup? I'm not saying he should put up all the money himself - I'm saying he should use the fact that he's now in the spotlight (because of his exclusion from the Sydney-Hobart) to announce his intention, start fundraising, and assemble his team (based on my posts to this thread, of course!).

If he wants Spithill & Ashby he'll need to start negotiating ASAP.

From Scuttlebutt tonight:

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
programme.

* 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.

I've thought all along that Artemis might fly despite the consensus otherwise. Today she almost did and may have just after this photo. This shows the windward hull up and the lee hull flying bow up with the stern still touching the water: (See following posts-I guess I'm wrong)click-

 

Look closely, you can't see the leeward hull, it's just the chase boat... I too was hoping somehow someway this boat would fly, that they knew something others didn't...

 

34th AC

---------------
Go to SA, the AC forum,under "Artimis" post 3268-bigger picture. The lee hull is clearly( I think) pitched up with just the stern still touching.
Evan, I just looked again and saw Steves post-I guess I'm wrong...
PS- Evan, you caught this 3 minutes before Steve Clark did-congrads...

 

I can see what you're saying and I first thought that too, but when you look at it there is the white area above what look slike the AC72 hull, then the black area of the windows of the chase boat which is right where the 72 crossbeam is, then the white roof on the chase boat.

 

An interesting article where Mike Drummond a former designer for Oracle appraises the current designs and their development progress.

http://www.sail-world.com/Australia/Americas-Cup:-Ex-Oracle-design-chief-looks-at-the-Class-of-2013/105594

here is part 2 of the interview where they discuss foiling and pitchpoling

http://www.sail-world.com/Australia/Americas-Cup:-Designer-Mike-Drummond-looks-at-foiling-and-pitchpoling/105592

 

I found the article with Mike Drummond interesting, he knows quite a bit and it was nice getting an "Inside" view. I wonder what more of the advantages of the pod on 17 are that he wouldn't talk about or that others have already thought of.

ETNZ released minimal pictures of boat two, doesn't look like the concept has changed much from boat 1, just a more refined version. It was interesting to hear wing 2 will be very similar, I thought they would try something a bit different.

Artemis' wing 2 is interesting, a much simpler version of their first wing resembling a mix of Oracle and ETNZ's wings. I was interested to see how the trade off of the heavier wing with more adjustable segments versus the "basic" wing design would work out.
