South Carolina | Doug: no its not.

That is definitely the Swiss' America's cup catamaran (somewhere between 90 and 115' long) being lifted by one of the largest helicopters in the world. To put that in scale, here's a picture of the Russian MI26 picking up an American Chinook helicopter (you know the Chinook? Our heavy lift military chopper that carries tanks?). ![[Linked Image]](http://www.defesabr.com/MD/Mi-26_CH-47_Afghanistan_Recovery.jpg)

Michigan | I'm sure that people much smarter than you or I have figured out exactly how much volume they need up there to keep her from going tits up.
yeah... i originally had some text in there about how I haven't a clue, but figured it went without saying. | | | Re: Alinghi's catamaran revealed today!

They're apparently relying on lifting boards that are located in the hulls forward of the main beam to help keep the bows out of the water. Agree, the bows are quite thin considering the boat is nearly as wide as it is long. My personal opinion is that it will probably work OK but it makes the margin of error even more unforgiving if pressed hard. These things will be capable of traveling at speeds that will cavitate foils. Additionally, having the boards that far forward in the hulls will not help the boat's tacking ability.

Sebring, Florida. | These guys are in "uncharted waters" here so it is possible they might have -miscalculated- what they need up front. Remember when Play Station had it's bows "fixed" after a near pitchpole out in the big ocean? I realize they are not going to be racing these things in conditions like that or in the open oceans, but still, mistakes may have been made...
However, Bertarelli has quite a bit of experience racing rather large cats, so maybe he wants it just like that, it is he who picks the venue, right? Maybe he'll pick San Diego and built it for the light air prevelant there.

My biggest fear would be like what was happening to the Orma60 tri's that started putting t-foils on the rudders to keep the sterns down. They worked great but when they let go she goes tits up in a skinny second.... ![[Linked Image]](http://www.sailinganarchy.com/fringe/2004/images/GitanaCapsizeNet.jpg) These forward foils are going to provide lift fine until the bows find themselves pointed down...then the foils only help to exacerbate the problem and keep things driving deeper.

They just need to trap farther back.

Columbia South Carolina, USA | No one thought the designers of the Fox were in thier right mind putting thier hulls on upside down, now all boats including monohulls are going for the wave piercing technology. These days the Tornado hulls look upside down!

Naples, FL | dude, you're on your own. the second you said i do and sold your boat you knew willy would never be free again. I'll probably be about the same size, too! But there is a very small glimmer in this tunnel. The oldest kid is doing well with swimming lessons this week. Can I tow an A cat with a Lotus Elise? I think the trailer would weigh more than the car.. but it would look awful sweet...
