Ok, so the foils are lifted and lowered by battery powered hydraulic rams. Presumably the controls of mainsail, jib etc are also hydraulic, are they also a component of the battery powered system? If so, then are the grinders simply replacing the battery energy used by the hydraulic pumps by turning battery charging alternators or dynamos? How long can the batteries power the hydraulics without being charged before they run out of power? Must the boats finish with fully charged batteries? The grinders are obviously working hard almost all the time I'd love to know how the whole battery, hydraulic, charging system works. Does anyone know of of a web site or video that explains it?
Яхта Luna Rosa Prado -это любовь ❤️ с первого взгляда. Грациозная и восхитительная как Италия, быстрая и взрывающая самые невероятные ожидания. Самая дерзкая мечта моей жизни -ступить на борт этой яхты. Мечтая об этом - слезы льются ручьем из моих глаз. Это настоящая любовь моей жизни ❤️💗💕💖😘. Спасибо создателям этого творения. Этот шедевр на ровне с творениями великих Итальянцев, таких как Микеланджело 😍
The upper foil surface longer than the lower in the elongated droplet shape assists the laminar flow, but is not the main reason an aeroplane or the AC75 flies. It is the angle of attack of the foil towards the direction of flight that creates lift. Think of a simple kite with nothing more than a single plane keeping it in the air, just like the first stick, wires, and cloth skin aeroplanes could, or a paper folded aeroplane can fly. Amazing machines those AC75s have become! I just find it a pity that it became accessible for even less teams. I hope to see more teams than just four competing in the next America's Cups to come
At a guess you would have multiple sonars to detect the heights and gyroscopes combined with accelerometers fused with software like an extended Kalamn filter. This would control the flaps to maintain lift, pitch, roll and more.
Double main creating a "tacking wing" was invented in Catamarans in the late 1970's and sailboards in the late 1980's....were too heavy for both back then.
Are you talking “camber induced rigs” for windsurfers in the late 80’s early 90’s? If so I remember they might have been heavy for the smaller boards, but on long race boards they were rock solid fast and stable. I know what I found more effective!
Same here. These are so fun to watch with outrageous speeds. But the races are over so quick. I was on the water in 2000 in NZ with traditional monohulls. This lasted about 2 hours and you could follow from mark to mark. Not anymore.
To my knowledge. They are generating hydraulic pressure so that the trimmer can adjust the sails. Might be wrong but that was their purpose in the past on other boats.
Very good and thank you. I am curious though, and in debate with a number of friends, to know what the equivalent HP the sails are generating to propel these beauties to 50kts? Any thoughts, scientific or otherwise?
The old farts of sailing are still complaining about the high tech of this AM Cup, they want to go back to boats doing 4 to 7 knots speed, how boring. Lets embrace the new tech and time and hopefully the young ones take up the sport.
Frankly this looks more fascinating than F1. I'm a physicist, and i love that learning the rules of the universe and combining it with finely tuned engineering, regularly results in completely absurd outcomes. Like boats doing ridiculous speeds on wind power alone.
There is so much future in sailing. With that said I would watch races of the real old boats ( with modern TV tech however) - fascinating strategies and all . . . .
@@Logarithm906 these boats use same technology as an F1 car, the wings, ailerons, speed thru aerodynamics and fluid dynamics (air is a fluid before anyone comments)
Here is what I don't understand. Last Cup, one team changed the grinders from arm crank to leg crank. Makes sense as the legs are the biggest most powerful limbs in the human body. Forward to current Cup, I see everyone is back to arm grinders. Why?
There was a change in regulations and it is no longer allowed. I guess since they won, they reveiled their edge, so there was no reason keeping it there any more, since all would copy in the future.
I don't understand much about sailing but I follow the America's Cup for many years (since first italian challenger Azzurra) and I don't understand some controversies I've read (about the boats); too many people are nostalgic, they say that these boats don't sail but fly, talk about the dear old boats, the "true" match-races, the Spinnakers and bla bla bla. I'm not more a guy (unfortunately I add) but I really don't understand, time passes, everything evolves *(not my eng, sorry)* because this shouldn't happen for sailing and (firstly) to the America's Cup? It seems very silly (a nonsense).
After watching this.... not a single mention of eight guys `pumping iron`, as a total land-lubber no clue was forth coming as to the technicalities the crew performed..!!!!
@Zack Cawvey Oh lordy no! Compressible and incompressible fluids do NOT "act similar". And cavitation is in general a very bad thing - outside of supercavitating torpedoes of course - as it causes drag and surface damage. Are you saying that the hydrofoils are cavitating?
I believe the regulations state that the batteries that power the hydraulic system can only be charged by human effort, so they're effectively just on a human hamster wheel
i still not fully understand these sail racing boat how it work, i understand how to lift work, but how to use wind and sail to make forward movement and go freaking fast like a moto powered speed boat??if i rotate the boat 45 degree to look it, is easier to understand??so if take the all part off the boat , but only have that big main sail, when wind hit main sail, create uplift force like a airplane, in theory the boat will keep running circle right?? sorry for my poor english.
A simple explanation is like this: an airplane wing installed on a plane in horizontal position, and when the wing cuts through air, an artificial wind is created which lifts up the plane. Now if you install the same wing on a sailboat but 90degrees up in vertical position, what do you expect? There is a natural wind blowing into this sail, the same aerodynamic effect would now push the sail/boat forward instead of upward (remember the 90 degree change in angles of the same wing), as simple as that.
They hit 45 Kts just before the capsize . The 50 Knot barrier has been broken a few days ago. That's sailing 4 times the wind speed. These are truly fantastic boats and have to be seen to be believed.
If the cantilever arms are run by batteries, why have those idiots playing patty cake. Replace them with batteries. Or at least replace them with a bike mechanism, so only one is needed, instead of two.
"Whilst the batteries control the main foils and rudders, everything above the waterline, including every sail control, is powered by the onboard grinders using pedestals supplied by official Winch Systems" - www.ineosteamuk.com/en/articles/271_The-grindhouse-rules-powering-the-AC75-with-Harken.html
I think they wanted to keep the illusion of it being an athletic sport and not just an engineering and driving battle. And to make it look like they are still pulling ropes to trim the sails (which they definitely don't) Realistically each of these guys can output a maximum of 300W of power over a time of 3 hours (could hit 400W if they were to use their feet instead). So to replace them with a battery you'd need one with a capacity of about 300(watts)*8(grinders)*3(hours)*3(safety factor)=21,6kWh, which would weigh about 90kg with modern battery technology. Thereby saving close to a ton of weight (both the grinders and the grinding fixtures)
@@danielweston9188 "High-speed Sailing drones" sounds like something I'd definitely watch. I wonder how much faster they would be than the current boats
@@johnharrison2741 Is that correct? The video said the hydraulics are battery powered. So could they be turning generators to charge the batteries, not turning hydraulic pumps? I've not been able to get a clear answer about this.
@@douglasburnside I am no expert, but as far as I know the foils and rudder are powered by batteries that power hydraulics for this system only. Everything else (above the waterline) is powered by humans turning pedestal grinders, that provide hydraulic power on a separate system. The hydraulic power is stored in accumulators, so that it is available to do multiple functions on demand and re-charged when there is low demand.
Grinding coffee thats why ineos isn't going so well because they just want a cup of tea, & as the video says they (I think they mean Team UK) keeps swamping techs! Really I would expect better quality creations from Prada but ...
Next teep : Canard configuration ! ..... Get Burt RUTAN involved, and adopt the Canard configuration ! Same hydrodynamique lift for less drag. No horizontal bearing surface at the rudder as it is now, but instead, a "small" bearing surface at the front (at the "nose", the bow ), (with elevons ....).

@@grantober1726 Actually they very well could. There is no human strong enough to directly trim such a huge sail too... Yet they use the grinders to power the winches that do so. Hydraulics and leverage are an awesome invention
I think the main reason the designers went with airfoil was to speed up the races since the races of old took so long and were boring as fuck to the average viewer
Foiling is the best thing since the winged keel. I don't think it's safe having the foil up in the air . Crew will get chopped up if a colission happens .
These Yatchs throw a very Interesting Idea at Flight and Planes. Should we Look at Designing a Plane with Both Horizontal and Verticle Wings ???. Also we Urgently need High Quality Fast Passenger Sail Ships, so Hopefully some of this Technology Transfers to that area.
Then it won't be sailing sport. The yacht must be controlled by human muscle power and brains, and only devices that facilitate physical activity are allowed. With electronics, it will then not be a sport, but a personal transport for rich people.
But seriously, why not use that motor in the water? Isn't the whole point of sailing racing missed when you use an electric motor to harness wind power instead of sails and manpower? I know there are still sails and men, but that whole rig is designed to capitalize on what they're able to achieve thanks to the electric motors which are able to lift the wings.
Great video. Cleared a lot of grey areas for me. Thanks, Prada.

Yea but we all used to watch the old boring races and now fuck all watch it. Remember the red socks!!!
Speed = broader spectator interest. Gonna be something when two of these collide at 50kts.

I guess, this foil wings will kill a lot of fish!
Ну вот и наконец американцы догнали старые советские технологии! Молодцы, даже людей в космос начали запускать.
Foiling is the best thing since the winged keel. I don't think it's safe having the foil up in the air . Crew will get chopped up if a colission happens .
Hypothetical. Crew could get eaten by a giant octopus 🐙
@@fburwell3629 can't sue an octopus. Can sue Prada, rich boat owners, organiser etc.
These Yatchs throw a very Interesting Idea at Flight and Planes.
Should we Look at Designing a Plane with Both Horizontal and Verticle Wings ???.
Also we Urgently need High Quality Fast Passenger Sail Ships, so Hopefully some of this Technology Transfers to that area.
It is possible that the next step will be controlled by computer + motor.
Then it won't be sailing sport. The yacht must be controlled by human muscle power and brains, and only devices that facilitate physical activity are allowed. With electronics, it will then not be a sport, but a personal transport for rich people.
But seriously, why not use that motor in the water? Isn't the whole point of sailing racing missed when you use an electric motor to harness wind power instead of sails and manpower? I know there are still sails and men, but that whole rig is designed to capitalize on what they're able to achieve thanks to the electric motors which are able to lift the wings.
