challenger series to be raced in these: a one-design 45 foot hard-winged cat.
AC45 First Sail Auckland 16 Jan 2011 (http://www.youtube.com/watch?v=G0qXv1-ImGw&feature=player_embedded#normal)
the cup race to be raced in 72 foot box-rule cats. Box rule is just that... your boat must fit in the dimensional box set, but other things are open. The 72 cats should be awesome.
oh...and it's going to be in San Fran bay. ;D
Last year while we were on vacation we crewed on an America's Cup boat as an excursion to a Cruise down in Cabo. It was absolutely awesome! [thumbsup]
how fast do those things move on crisp open water....30 knots?
30 is being discussed as a top end. they've done more than 20 in less than ten knots of wind already.... and it's only been a few days of testing the first hull. (in ten knots of wind I can go ten knots...but only in the perfect direction. most cruising sailboats would be doing about 5)
The hard wings on these aren't as complex as A cat wings or the wing on the BMW trimaran in AC 33. But the one-design aspect is interesting.

What do you sail? A-Cat?
I can't wait for the 72 ft cats.
nothing so exotic. Corsair 28.

I'd make the beast with two backs that thing up so bad...
No shit. I was thinking of the carnage from pitching my little 19, I'd snap all sorts of shit on one of those beasts.
I'm hoping it looks like the extreme 40s.

This bay is going to get very small very fast.

Yay. My boss gets to spend more of
the company's his money but at least it'll bring huge crowds to town right by where I live.
Why couldn't Larry have been into motorcycles? :'(
that is going to be sweet!
i have always preferred the 1 design races.
day 2 (TWO!) of testing on the water and they're over 27 knots on the first 45. ;D

frikin awsome!
Interesting... I'm gonna go ahead and assume that's a stabilizer on the port shell? Ot would make sense if it's used to attain a higher control of the balance when flying?
are you talking about the dagger boards?
Yeah that's just the daggerbord (keel) pulled up to reduce drag.

Interesting, didnm't know that was possible. Though, at the speeds they are attaining, I wonder if they taken into account the aerodinamic consequences.

PROS
A daggerboarded cat will sail consistently higher into the wind than a cat with keels. Typically between 5 to 7 degrees higher. This added speed and pointing ability represents a significant safety feature when cruising because it enables you to claw off a lee shore or to arrive at an upwind destination with far greater alacrity. Sometimes you cannot “run for cover†â€" you must “beat for cover.â€
A daggerboarded cat, all things being equal, will sail at least 2 knots faster, on average, than a catamaran with keels simply because it isn't carrying the enormous fixed hydrodynamic drag (i.e. wetted surface) of two long and deep fixed keels. This added speed is a significant safety feature for long-range cruising. Not only are long passages cut shorter, reducing exposure to adverse weather, but should one encounter adverse weather it is much easier to either run from it or avoid it entirely with proper weather routing. A faster boat always increases one's options, and therefore increases safety, when cruising.
A daggerboarded cat typically draws 2 to 2.5 feet less water than a cat with keels. As such, the sailing grounds and potential anchorages available to a cat with daggerboards are considerably larger than those available to a keel cat.
In extremely severe seas daggerboards enable the skipper to adjust the balance of his catamaran by raising and lowering the boards. When sailing in large cross-seas you typically raise the leeward daggerboard entirely and lower the windward board half-way to prevent being tripped over by a breaking wave. A keel cat is stuck with the keels down, all the time â€" as such, there is no way to prevent the boat from “tripping over herself†in storm-force conditions.
the stuff quoted above is realy about cruising catamarans and the pros and cons of mini keels versus boards..
the boards on these boats are asymetrical... airplane wings sort of. They are designed to keep the boat from slipping downwind, just like any daggerboard, but they are different each side. This is coming to cruising boats too but as everything it's a trade off. symetrical boards can be switched if one breaks while in the middle of the ocean.
Much less drag in the air than in the water, which is why one is pulled up.
There has been some dissappointment among enthusiasts that the ac45s don't have curved boards... curved boards are being used to create much lift as well as resist leeway. More lift on the leeward hull means more sail area can be kept up. The ac45s also don't have canting rigs. So these aren't cutting edge boats realy in terms of every go-fast tech bit already out there... but look like great training boats for the upcoming 72s.
I soooo want a ride.
dream boat. Wife thinks, (and I have to honestly agree) it's a little on the hot end of the speed/crew/cruising continuum.

notice they are being lazy and leaving both boards down. (not an issue with symetrical daggers but these are asymetric. No huge loss, but if racing would raise windward one.
That's a giant rotating mast in carbon.
Hugo LeBreton, the guy who builds them, invited us to sail when we were in Europe last summer. Still kicking myself for not scheduling the time in.
gotta stop looking at sailing vids with all this snow out the window. :'(
This is really interesting. I've actually been thinking about taking sailing lessons in New Orleans, partially because it looks incredibly fun, but also because "tacking", "going large", etc seem really mentally challenging.

exciting!
and people said the prestarts wouldn't be exciting. This is going to be just crazy on the 72s.
