34th America's Cup: multihulls!

The early testing of the AC45 wing extension by Emirates Team New Zealand has been successful. The purpose of the extension is to help lift the weather hull in lighter winds, and for it to be easily removable when stronger winds are forecasted. The nice surprise so far is the ability tocarry the wing higher in the wind range than originally anticipated.

 

Guess that's what happens when it turns into a spending contest, the richest team has no one to play with.
Which is why we have defined classes and box rules etc.
Just thinking aloud.

34th AC

Great insight into USA-17 by Tom Speer-probably the best I've read:

Look what Lock was doing in the early 70's.

34th AC

Commentary from Steve Clark on SA:

I was at a presentation by Ian Burns early on when the initial plan was announced.
The gist of it was "Yes, the programs will have higher budgets, but these budgets will be sustainable because the America's Cup World Tour will be valuable and so sponsorships will be more available."

I have heard versions of this line of crap so many times you wouldn't believe it.

Unfortunately the marketing value of the America's Cup World Series was and still is unproven. There is no history of yachting being successfully packaged as sustainably profitable entertainment package. This is a risky proposition even with the America's Cup marque. So prudent marketers are reluctant to invest significant dollars with limited prospects of success. This is how marketing people lose their high paying jobs at big companies, so "No, thanks" is the likely conclusion of any sponsorship discussion.

What we know is that it was going to cost a whole lot. Early adopters are asked to share in the cost of creating the value of the circuit, but there is little incentive to be one of those early adopters. The only motivation is that you are passionate for the America's Cup, and because of the increased costs associated with this cycle, one needs to have two extra extra zeros at the end of one's personal financial statement.
The more prudent course is to sit out this cycle. It will cost less to buy in in 2 years and you will have surrendered nothing.
From an business standpoint, AC34 makes no sense.
On the other hand, just because so much is at risk, it's potentially really exciting, and I wish there was enough money out there to pay more than 3 design teams.SHC

 

The original cup was fought out in tea clippers. Wouldn't it be great to see the format change to something more relevant like sail assisted oil tankers.

AC 45 ---foil!

Check out the lifting foil in this picture of an AC 45(which AC 45?) : http://www.xssailing.com/

Another real interesting design development: the boat with the "L" foils also has the daggerboard trunk in front of the forward cross beam:

If the dagger foils were in the conventional and theoretically correct position the boat would be a tip truck, that is a tip truck rocking forward (and backwards too) - a guaranteed pitch-poler. Now the interesting thing will be to hear about helm balance - do they have savage weather helm with the centre of lateral resistance moved forward? My guess is they can't tell the difference, maybe a fraction more weight and that is all.

 

Ac 34

=================
I think you're 100% right-not only that but they could correct any balance problem with slightly larger rudders a la Bill Roberts Arc 21 "shared lift" concept. The thing is that in the old position the boat had a great propensity to pitch pole! Look at any of the windy video.. This could help a lot in addition to reducing wetted surface.
