How Did Oracle Team USA’s AC72 Capsize In The “Death Zone”?!?!?

“Sailing Tips”
When the AC72s of the 34th America’s Cup first lifted off on their foils they attained great speeds of more than 50 miles per hour, or close to three times faster than the wind, which few of us could ever have imagined. In fast these boats turned out to be much faster than even the designers…

I try to make my videos succinct and appealing to a broad audience, so there are sometimes details that are omitted from the final release, but which may be of interest to some:
• The AC72s follow a “box rule” which establishes overall dimensions and gives teams freedom to design and implement different solutions (e.g. wing designs). The full rule can be viewed at https://www.cupinfo.com/en/ac34-americas-cup-2013-ac72-class-rule-01.php
• The AC72 rule initially allowed for different sized wings, but was later amended to a single wing as a cost-saving measure.
• The final wing dimensions were 255-260 square metres (2,745-2,799 square feet), 38 metres (125 feet) high, built in two sections which could be disassembled, with the lower section between 18-19.9 metres (59-65 feet) high.
• AC72 wings were relatively simple and “low tech” compared to more modern AC50 wings.
• The “death zone” differs boat-to-boat, but is at approximately 95-105 degrees off the apparent wind, or just below a beam reach.
• Above the “death zone” (i.e. sailing upwind) the helmsperson can steer towards the wind to depower the boat.
• Below the “death zone” (i.e. sailing downwind) the helmsperson can steer away from the wind to depower the boat.
• Inside the “death zone” steering alone cannot reliably depower the boat and the only alternative is to ease the sheets, but if the sheets cannot be eased for any reason bad things happen!
Lets be clear here about how the USA won this particular series, they had software that took over control of the aspect in the horizontal that gave them their advantage, according to the rules they were completely fraudulent in their victory, so ….not "somehow?", they fucking cheated, same as they cheated in the pre series and had points or races taken off them! They couldnt compete without cheating!
Capsize in a catamaran is much more dangerous than a monohull, and while I know a trick for righting a Hobie (small light boat) it still requires another boat to assist at least in Bay conditions.
Technological multimillion boats that aren't' sea worthy. They ruined the America Cup with this crap that nobody watches any more including most sailors.
God know how the hell they ended up with these type of boats competing for the cup.
Ridiculous boats.
It's not the course that's the problem. It is that the boats are all designed with "death bows." Hydrofoils inevitably ventilate and/or cavitate – and then they fail. Putting a bow like a stiletto on these boats is just plain stupid. These bows were designed for displacement hulls. Not flying hulls. At least they've moved away from these a bit with the monohulls. But not because the ability to realize the failure in design.
Sad seeing that beautiful ship all busted up.
I would guess the hydraulics on the sails didn't work. Or the driver failed to keep the boat under the mast.
The USA's seem to be making a habit of capsizeing AC boats. They flipped one in NZ last year and now this one. The
Larry Ellisons wallet shifted to one side of the boat.
Why would you show me that! I feel just like I did when Bambi's mother died 😔
…….
SF Bay will kick your booty if you aren't careful.
How can a boat be faster than the wind that is moving it forward In the first place?? 😮
I wonder if they should force teams to have a moving element on the wing to quickly stall part of it to prevent this from happening.
went looking for the limit ….found it
I was your thousandth like
This is incorrect, the best part of rigid wing sails is that you can actually INVERT the top of the wing to ease off sail, that’s why wings are so much better, you can control each element on their own and precisely, unlike a sail. Delete the video this is such garbage
When asked how did it feel to spend $100,000,000 to win the America's Cup. Larry replied much better than spending $100 million and losing.
I miss the AC 72's do they ever race and where are they today?
Just a few million dollars…. Just a few.
Thank you for the explanation for us newbs.
Thanks for very clear explanations.
Actual capsize not caught on camera …. So if you’re here for that you’re gonna be disappointed lol 😂
My face when something bad happens in "the death zone" :/
Death Zone. lol. Never heard of that in 40 years of sailing.
It’s not really sailing it’s drag racing on winged tennis courts. Very nice if you like that sort of thing
