34th America's Cup: multihulls!

Grant Dalton has quite a bit of experience with catamaran development having competed in and won 'The Race' on the maxi catamaran 'Club Med'. In that event the most radical maxi cat was the Pete Goss/Team Phillips catamaran. Grant was obsessive in his desire to break 'Club Med' in the training phase and drove it madly back and forth over the Atlantic till it broke the structural design was then reviewed by "High Modulus" in New Zealand much to the discomforture of Giles Ollier and quite a bit of strengthening added. History tells us that the most radical or fastest design doesn't always win the America's Cup often the best drilled team with the maximum amount of on the water experience and the most reliable boat will win. I think ETNZ will be feeling quite pleased with their progress so far.

 

Hello all been following the thread and was wondering if anyone has come up with any estimates on the section shape for each boats foils? Or failing that any links to any good detailed photos of the foils???

 

New pictures of Oracle Team USA 17 repairs and you can see hulls for boat 2 in one of the photos: http://www.sail-world.com/USA/Americas-Cup:-A-look-behind-the-door-at-Oracle-Team-USA/106167

Not many visible chagnes after the capsize from these pictures.

 

EvanStufflebeam, thanks for posting the link. Those are great photos.



All of that work looks labor and $$$ intensive.

Little guys and dreamers without deep pockets, are verbotten!

 

I did find one difference after looking more at the photos. On the original front corssbeam it was verry narrow, with a large faring, but had a cut out from the faring near the hull pod and winch, in the new photos the beam has no cut out of the faring, meaning we don't know the new size of the crossbeam, and how much of it is farings. Could make a signifigant impact on the torsion if they increased the corssbeam strength.

Click on right video, you may need to refresh it if it doesn't load through at first, I will post pictures once I get them

 

I found links to two extra-large (2126x1417) photos from that same set of pictures:

Foils look interesting, looks like much more area on the flat "winglet" portion of the foils.

 

A few links on the ETNZ launch seems they were concerned about gusts when fitting the wing so put it back in the shed after some load tests.

34th Ac Oracle 2 flies!!

Great pictures but we really need a video to see how she's actually performing....

Hopefully it will prove easier to control because those bows aren't going to save the day if things go wrong in a breeze again.

 

34th AC

----------------
If the foil system works- so it can be rapidly adjusted- they won't need reserve buoyancy from the bows.

Be sure to click on this photo. Oracles photog is quoted as saying they smoked Artemis. A video of this picture would sure be interesting:

Artemis is in this picture-click on it

 

==================
Another unnamed poster(post 6711 in the Oracle thread on SA) has verified what my friend and I have said about altitude control on Oracle. So far , no mention of the word "joystick" but this unamed person said the foil is adjusted hydraulicaly while under way.
