- ORACLE TEAM USA resumes it's San Francisco Bay training program to near-perfect conditions, and the presence of two newly arrived challengers in Luna Rossa and Emirates Team New Zealand. With only a few months remaining until America's Cup racing begins, the testing program carries on at full speed. [ © Amory Ross / ORACLE TEAM USA ]

As an old sailor, from the Navy to small sail boats. I have seen what I thought was everything. This stuff however is out of this world. Wow what I would give to ride on one of these machines.
ОЧЕНЬ КРУТО - драйв,адреналин !!!
Amazing...
Awesome beast!
Go Oracle Team USA!
yes
Феноменальная , слаженная работа команды!!!
These guys keep getting better and better -- learning how to keep the cats at max speed all the time. It will be interesting to see if these 72s will be able to foil upwind in strong breezes.
thea and earth are so small. true true smilingly smally. not only thea and mariya know .
Красавцы
as far as I know they cannot be adjustable while sailing so they have to be set before the sailing or at very low speed. having said that I'm sure they play with the angle of the whole foil angle.
Flying on port tack at 0:45. Windward foil is lifted; see it drop at 1:13. Neat, huh?
Yes, Yes, Yes :):):)
The music for this video is awesome!
Are the main foils computer controlled or manual?
We have plenty of wind up here in the Great Lakes . How about you bring it up here in Michigan. We would love to see you race up here in the Detroit !
yes at this stage Team NZ seem to have a clear advantage foiling up wind, not sure what Oracle are doing wrong on the wind but they are running out of time to get it right...
There is a lot of running involved to..... ;)
I think the best foils are the curved ones because, if they start to come out of the water, they lose lift.
Yeah, but surface piercing foils are prone to ventilation. The effect is where air gets sucked to the top of the hydrofoil and sticks, due to the underpressure. This causes the hydrofoil to lose lift rapidly as the flow of the inccomming water is seperated from the hydrofoil. Also, a curved shape is less efficient as it's lift vector is never straight upwards. This could be useful ofcourse! The J-shaped foils on their boat have inverted hydrofoils. When their main T-shaped foils get pulled out of the water, the J-foils are used to restabilize the boat so it won't roll over. Very useful when sailing!
what music?
MURRIICAAAA
or something like that i think
Darude - Sandstorm
хуйня музыка - лучше блять тишина :))
What are the sailors turning the handles doing?
raising, lowering dagger boards. Trimming, easing sails. The position on the boat is called a grinder.
Thanks! Do the dagger boards have the foils on them or are those separate?
The dagger boards are straight at first and then curve into a a foil shaped like an oblong "U". They are shaped in a special way so that when the boat is in the water, they create lots of lift upwards. As the dagger boards come further out of the water, the foils are shaped to create less lift. This makes an equilibrium point and then the boat stays level on its foils.
Go to 0:45 second mark. Windward foil is lifted.
2:15 What happened to Andrew?
I had one of these but I couldn't afford the payments
Wind walkers, sea stalkers.
Nice Yank accent from Down Under
thats what i'm saying, its not Team USA, more like Team Aussi-American
Still ORACLE! (Y)
its an airplane
nobody is foiling upwind
AC75 are much more beautiful!!
