Another great find, Evan! They seem much more stable than when Oracle first foiled their 45's last year. Can't wait to find out what their altitude control system is. Seems like it must be manual because they don't seem to get any lift from the daggerboard-just the foil on the bottom.

 

Being a Design Engineer involved in many development projects I'd like say this. Its always tempting to change or tinker with something like Artemis's #1 boat. But this has to be resisted. Especially since #2 is on the way. Its more economical to do all the changes on boat 2. Plus the design team is trying to establish if the #1 has met the design intent. So the on the water development has to concentrate on establishing that every design element has acheived (or not) its goal. Once every element (or concept) has been proven or disproven, review and understood, then #1 can be tinkered with. Unless the design goes horribly wrong and emergency modifications have to be made then changing anything has to be resisted otherwise the variables become huge and you will not know what is actually making the difference. Especially in the first set of AC72's ever built. We will not know the correct "design space" until thay actually race. So in some ways this shows that Artemis has hit their design goals with this boat. Everything learned on #1 will go into #2. Again in some ways the pitchpole of 17.1 gave Oracle a chance to go to 17.2 very quickly as they had to get a boat going real quick. So there was no inertia in waiting for Oracle No2 it may have even speed up their program. Cheers Peter S

 

Stumbled upon cupexperience.com and found some pictures I found interesting. His beautiful photo edits show interesting buttons on the wheel. Maybe the wheel was a bit more of a tactical choice than they let on.

Here is the story of a sinister plot by TNZ, or evidence of group insanity, or could it be humor? Nah......

You'd think they'd be a bit more energetic with all the coffee they claim they drink. I think I'm going to need to be sponsored by Nespresso to sit through more interviews with Dean and Nick.

 

Well there you have it folks, Millions of dollars spent on design and construction of amazing flying catamarans, and the winning ingredient turns out to be coffee

Gotta love the Kiwi sense of humour

It'll be good to see our bro's across the ditch beat up on Oracle Team USAustralia and bring the Cup back to the right side of the planet

I'm afraid that it's the apparent superiority of Oracle thats keeping them up late at night.......
Go 17ers!

 

I think it's very generous of you to root for the Australians Doug, and even more generous of Oracle to pay for it !

 

Interesting, Artemis removed the video of the foiling 45.

 

6 videos of Oracle training, lots and lots of foiling. http://www.sail-world.com/USA/Ameri...ore-foiling-in-San-Fran---Am-Cam-video/108006

 

So after all my posts bemoaning the absence of an Aussie challenge you're telling me you've been there all along (in a guerilla leverage sorta way) ...?

 

What do you call it?
Interesting? Sounds kinda weak. Interesting?
But over there at Sailing Anarchy referring to Artemis foiling on their 45, words to the effect that it was a DEBACLE that Artemis 72 was NOT foiling.
How things change.
What are we talking, 6 months? - (doesn't seem long ago) when only the enlightened Kiwis were flying and there was still all this BS about Archimedes and the loss of plodding match racing ... and what have we now? .... a debacle that teams (backward teams) are not foiling/flying.
Plus ca change, plus c'est le meme chose ..... NON.
Bloody hell, Doug, you were right ... and now you're the messiah. LOL.

 

Oracle released this picture, caption said they were working on graphics of boat 2, on the paper on the deck you can see a edited picture of the boat, can clearly see the foil location is further back than on boat 1, and the bows look larger than the rest of the hulls.

 

==============
I wouldn't think they'd move the main foils back. Reducing the distance between the main foil and rudder foil is a sure way to increase pitch instability
and I don't think that would help Oracle. But who knows what rationale they'll pursue....
