Was hoping to learn how it's possible to sail at triple the wind speed. Instead, we got three minutes of "It's exciting."
Yeah definitely agree.
Here's my basic understanding:
Sails work not only by catching the wind, but also by generating lift like an airplane wing. Ironically because of this boats are faster going across from the wind (aka beam reach) than completely down wind (dead run).
@@garrettg5130 I like your fancy words
I’d rather hear the thing drumming across the water than the dada music.
Big sails+ less contact with water = More push and less friction. There..., explained.
@@Lobos222 That does an absolutely terrible job at explaining how something moves faster than what's pushing it along.
Wish the music was a bit louder. Could almost make out what they were saying.
I liked the music. Added to the vibe.
@@Mike-gz4xn Yea. No need to hear the commentary.
@@mchase4 I can hear it fine. Surprised you couldn’t.
get back on fortnite and make some content for some 8 year olds creep.
@@zacksmith5801 You must live a sad miserable life
ok, FAST IS A STRAIGHT LINE, SURE.... BUT THE TURNING ABILITY IS MIND BENDING!
Its the formula 1 in sailing world
have you ever seen footage of a black marlin.. that is mind bending.. also mind bending is all stocks and cryptos are down... HEX coin $0.04 .. i got in a .45 so im down on my original investment but .. it will be mind bending that im buying the dip when we get to new all time highs. today is june 28 2022 the founder has a new coin coming soon called $PLS ... it will be mind bending when it hits $0.01 its not out yet but i sacrificed at 10000 coins for 1 usd. hope it comes out someday....
They turn quicker than anything bigger than a Lazer. Gives me hope for real tactics and deeper strategies. The races themselves, however, are set up to minimize tactics and strategy.
I was a kid in the 70's when a boat designer made a catamaran with a wing replacing the sail to break the sailing speed record. I don't think he saw where the idea would go at the time!
Was that "Crossbow"?
Would have been nice to be able to hear the dialogue over that pounding music bed.
at first I was skeptical of the ac75, but now I think they are fantastic boats, it is the most beautiful and exciting America's Cup of the last 30 years, congratulations to Team New Zeland for introducing this new way of sailing, bravo !
Introduced by Americans. Not NZ.
@@cranegantry868 team NZ created the foiling era
@@slooob23 I was never skeptical, but a lot of "purists" took a dump on these boats. Closed minded have a hard time dealing with change.
The mono hulls on foils is a NZ design
While everyone is focused on the foils the real breakthrough in this cup is in the rigging. There are hydraulic cylinders and lines going into the kiwi boom and mast that they are just starting to tweak
Because the speed changes are so rapid, sail shape has to match that speed, so you have to go from full to flat in seconds and it’s constantly changing,
I think this is the main reason the kiwi boat looses less speed thru the turns than the challengers while the straight line speeds are very similar
I cant believe there are still the old school sailing fans knocking these amazing pieces of innovation. Top end racing should be about maximising what technology is available at the time, so what if it isnt the same as it used to be, there are countless opportunities to watch traditional sailing races. This is cutting edge and how it should be. Amazing! Cant wait for the racing and can.t wait for a world series being developed for these boats.
Racing boats are as far ahead of regular sail boats as Formula one cars are from the regular grocery getter. And that's the way it should be. Hopefully there will be some technology transfer down the line to aid regular sailors but there will be no advancement if the sport is not allowed to innovate. As long as the boat lives in the water and is powered by her sails its all good.
You'll have to cope with the fact that not everyone thinks like you.
PS. Love these new boats.
I don't know much about sailing, but is there a traditional style of boat required for the America's Cup? I think there should be room for innovation, but this is more of a technology race rather than sailing prowess. Are there rules like stock car racing...meaning a set design and parameters? Thanks
It's because they are maximizing the technology at the expense of actual good racing
What is missing from the Americas cup is innovation and challenge. They are still sailing at a fraction of theory regardless of exaggeration and claims.
Talk about about how fast the boat is,and never tell the speed. Whats up with that?
It's really freaking fast, faster than the speed of sound that is how fast... plus the loud music over the dialogue makes it seems much faster, you can feel the wind on your face now...
@@BLINDCABBY ahh sadly i couldnt hear him. Good ear though thank you
also sailboats dont have a set speed like motorboats do, they you know, sail. use the wind. so their speed depends on the wind. i know hard to imagine right?
@@elementalgolem5498 not hard for me to imagine. I should have said roughly how fast.
@@dustyharris1061 they did say they go 3x the wind speed several times
It’s all fun and games until someone goes supersonic
That's right people, Kiwi's do fly! Just awesome combining aviation and sailing into one epic piece.
It is crazy to watch how fast these boats are and how quick and nimble they are. Especially the turn radius.
Using electric motors will do that...
Wow that was informative and exciting! I learned how to say exciting with 14 different accents. .......
mind bending what humans are capable of...you'd think we could all get along...excellent video
Maybe its good that WE dont get along so we come Up With great stuff
There is a certain group that has been devoted for a three millennia to hurting others and one tactic is divide and conquer. But if I named them I'd be immediately thrown off this platform because they run it !
I loved the old ac class boat that raced in 2000, '03 and '07...and i never liked catamarans to play America's Cup....
These new AC75 are, i think, the best compromise between the old mono-hull boats and the new foil technology.
I love them. They can have match race to extremely high speed and at the same time they look like the old ac class mono hull.
The only thing that disappoint me is the low number of challengers...i hope that the winner will keep the same boat format... :)
This is a very expensive class - highly technical to develop and build. Sad to see an AC without the Aussies, Japanese, French etc, but you need a huge backer to be able to participate with this design...
Io mi auguro tornino ai monoscafi in uso dal 2000 al 2007. Erano molto più lente, ma c’era molto più spettacolo.
Le World Series le ho trovate veramente noiose.
Inoltre molti team del passato hanno detto che torneranno solo se torneranno le vecchie barche
@@giancarlic1 Anche a me mancano i vecchi monoscafi e quel tipo di regate che avevano molto più fascino. Ed ero scettico anche io all'inizio su queste barche. Ma bisogna fare i conti con la realtà: ad oggi delle regate come quelle fino al 2007 le guarderemmo in troppo poche persone per giustificare un ritorno economico per gli investitori: lente e poco "televisive".
Oggi invece i team investono in tecnologie che stanno già avendo ricadute sulla produzione di serie, le barche che filano a 40 nodi permettono di avere tempi tv in linea coi tempi di oggi e soprattutto attirano un pubblico molto più vasto. Senza contare che una volta si spendevano milioni di $ per guadagnare mezzo nodo, oggi con la stessa cifra ne guadagni 5 di nodi di velocità.
Io penso che gli altri consorzi adesso si stiano un po' mangiando le mani visto il successo che sta avendo a livello di visibilità.
Infine, bisogna tenere conto che le World Series sono state una "scusa" per spettacolarizzare i test delle barche che sono andate in acqua un paio di mesi prima. Io sono stracerto che la Prada Cup sarà molto più spettacolare: stanno ancora imparando come portare al limite le barche e c'è un margine ancora enorme sul come sfruttarle in termini di tattiche sia di partenza sia di navigazione pura.
Vedremo ;)
@@tullochgorum6323 Every class in America's Cup is very expensive and this AC75 is no exception. And a huge backer/sponsor is not enough to be competitive. Take Ineos Britannia: rumors said that they have almost the double of budget than Prada, ETNZ and American Magic (stimated in 60million dollars), but if don't have the right people in the right places you'll not win :)
I think, as i already said to @giancarlic1 , that others competitors are regreting watching the visibility and the success that this AC edition is having.
I was skeptical, because i'm a old mono hull lover, but this boats with their speed made me think again.
Now i love them :)
@@alessioanzalone9759 In general I agree. I think they look better than the cats, and there will be more scope for tactical racing. The starts should be exciting! But this really is a technical class. The rigs, hulls, foils, rudder, hydraulics, software systems... It's a huge undertaking to get one of these boats together. Hopefully they will keep this class rule for a couple of cycles. As it becomes better understood the development costs should come down, the racing should become closer, and hopefully more teams will get involved.
*THE AMAZING THING* is watching the speedboats, trying to keep up with them...
Really gotta thank the brilliant engineers who made it possible for anyone to drive dish hair yacht. Bless you math......bless you. 👏🤔
Bet the Vikings would like to have had a few of them
Why? Cant transport anything on it
And I daresay the viking long boats were perfect for what they achieved, crossing the north sea and infiltrating rivers carrying lots of angry people with weapons ....this thing isnt any of that
@@oftin_wong just a comment wasn't meant to be a debate.
@@leonbachman5345 fair enough they would marvel at it for sure
@@oftin_wong yes. It would have been like looking at a space ship.💫💫😳
@@oftin_wong make it bigger and you have all those things but faster
Love it!
This is freaking....awesome
They are so fast, the speed is unspeakable! LOL Crazy boat design tho.
These look incredible.
If Columbus had had one of these he could have made it to the Americas in a little over two days. A couple of peanut butter sandwiches is all he would have needed.
Makes no sense. There were no peanuts until he planted them when he got to America.
@@bubbahyde322 that’s the style of UA-cam analysis we never see in Parliament......

If Columbus had one of these the whole crew would be dead a third of the way across
Astounding.
When I was very much younger, I had a Comet that I sailed on Skaneateles and a Lightning that I sailed on Hopatcong. I thought I was going fast. I probably made 4 knots with a spinnaker
Yea Timothy, but it was fun and you loved it.
@@charlesclements4350 and you did not have to be very very wealthy
Wealthy, what is that? Never heard of it. I know what minimum wage is.
Sailing Hopatcong in nj is excellent
WOW! Imagine the evolution of these boats at the next America's Cup!!!!
Captain Cook's offspring...haha love it
I remember when America's Cup boats did not climb up out of the water. I remember when foil boats would drop back down to displacement speeds in the corners....Ooohh so long ago
This is incredible !!!
Its amazing! I would love the opportunity to be able to race on one of those!
Rosalyn Mayfield if you are a woman I'm sure it wouldn't be hard to get on. I mean it might be hard but that's what the rich guy wants. A long hard ride. ;)
Stopped by to say kool shot from above ,besides a great looking craft
Now thats a serious sail boat ⛵
Amazing!
Physics: exists
The crew of this vessel:
We don't do that here
They don't know about it, then it doesn't exist. Proceeds breaking the speed of light.
Someone should ski behind it. 😁
I volunteer as tribute! Just to see if it could be done. It would be so awesome.
...Using water skis with foils of course ;)
yes yu can buy ot

I just hope they never collide at full speed.
Yip that would be a formula One wreak on water.
If you can see, to sail on a regatta today there is not the same like one houndred years ago. today is like "the foggy mountain breakdown" song .. but, I love the technology that make possible America's cup
I wonder about that too. This sport just got a lot more dangerous.
That would definitely be a spectacle
And they sometimes do!
The results are spectacular with guys flying through the air and getting hurt & caught in the rigging, etc; not to mention doing hundreds of thousands of dollars worth of damage to boat & sails.
Excellent stuff bro
Now that’s a rich man sport!
It's rich thanks to all the sponsors on the sails and hulls - the actual sailors are only rich men due to success and they may only enter the sport due to sponsors from grassroots origins. The sport is still just as impressive and intense as any other sport
I can buy a small, decent sailboat for $2000 where I live. It can't do what this boat does, but sailing doesn't have to be as expensive as these boats.
@@pistolen87 I think De Nguyen was talking specifically about the America's Cup. Years ago I did wind tunnel testing for a couple different America's Cup teams and got a small peek behind the scenes. The people behind these teams were billionaires. I doubt that has changed.
Also, after having owned a comparatively affordable boat myself for a few years, let me tell you that the initial purchase price is just the start. I don't regret buying the boat, but it was not an inexpensive hobby.
@@willdejong7763 All true, I just wanted to share some counter arguments to the statement that sailing is ONLY a rich mans sport. This kind of sailing certainly is, but not all kinds sailing is. Of course, everything is relative and if you live far from the sea or a lake, participating will cost more and unforseen costs and repairs can come up, but I just want to make the case for the people who feel discouraged by this statement.
It always has been. The .1% just keep getting richer and richer.
First time I planed a dinghy I thought I was hot shit.
These boats are amazing!
I saw a race a year or two ago and it was like Private Ryan Goes Sailing! It was 40+ knots the camera is shaking bits of cowling are flying off!
I was expecting an explanation, how can they go at 3x the wind speed?
because a sail isn't like blowing on a napkin, its more akin to wind, the wind over the sail applies a force, through the mast, to the hull of the boat. So you can get, through pressure forces, a force pushing the boat which, because they have so much little hull in contact with the water, and thus drag, is relatively very high.
@@pinkyfull Ha?
@@duerandaggi Google it. Sails aren't sails, they are big vertical wings.
@@pinkyfull Gee, what a great idea, thank you!
Sails are not directly pushed by the wind, that would actually limit the max speed of the boat to something less than the speed of the wind. The wind just gets diverted in a different direction. This change in direction applies a force to the sail. If you have a big sail, the quantity of wind you can divert is big, that means that the mass of the wind you forced to change direction is big. If the mass of your boat is less than the mass of the wind you diverted, and the friction of your hull doesn't dissipate that energy, you'll get an acceleration and a final speed greater than the initial wind speed. In another way, think of a teeter tooter: if a light person sits further along the arm she could balance an heavier person who sits closer to the center. Now think about the heavier person jumping on the teeter tooter, in a point as further from the center: the lighter person would be thrown in the air with a speed greater than the speed with wich the heavier person landed on the teeter tooter. In physics it's called conservartion of momentum.
Literally cutting through the water. Wow!
"One must admire the speed. These boats are very: fast, quiet and unique. Nature's wind power is truly extraordinary." 👍
*whilst not showing one single clip that conveys just how fast they are.
Someone else’s taste in musuc is the main subject here.
Whole lot engineering went into these sailboats!
wow so damn cool, ...
Look what a winged keel in 1983 has lead to
When I used to race RC tunnel hulls and hydros, I got “called” all the time by competition. Judges would always want to look at the engine. It was stock. The loser/caller was allowed to buy the engine which they often did. I’d drop on another new stock engine and still win. It was the boat hull, turn blade and the tuned prop. Well within the rules. Just before race and after inspection I’d nonchalantly swap the prop for a dog performance one, because people loved to copy. Not giving away what I developed lol. Hydrodynamics is the name of the game. Sometimes just a very subtle change makes things just fly.
I love how the American has an Aussie accent.
Dean Barker? He's a kiwi
I was about to say the same thing. He is just the skipper for the American team and that’s why the US flag was next to his name.
Congratulations gentlemen. Great job on mastering this new technology. I wonder how long before we can buy little boats I can do this. Like a dinghy racer
Moths mate. That's what they modeled these on.
Look up, windsurf hydrofoil it is fun, relatively easy and exiting. Speed up to 38 knots on foils:-)
I heard they already have small ones being used at the moment
@@Beanione Moth. Been around for years...
You can do so right now. Foiling moths are available now.
That's just awesome regardless of what anyone says. 😳😃
Jungle Jargon yup ... some rich men buy sports teams and race yachts and other rich men build subs that can go to the deepest depths and build rocket ships to take people to outer space. Everybody needs a hobby. I play cribbage and make comments on youtube.
@@donvandamnjohnsonlongfella1239 LOL!
ITS ACCELERATING at HIGH SPEED. !!! 👏👏👏
I remember when Cup sailing had sailboats in it.
They’ve always been pushing the tech farther and farther. Traditional keel boats are obsolete.
@@Vl7248 So is yacht racing then. These things don't belong in that category. I'm fairly certain if some competitors revived more tradional boats in a different, more traditional class, they would be immensely popular. Perhaps more so than these things. I'm not suggesting you are wrong, I just wish you were.
@@joeespo177 chariot racing eventually went away... fashions fade to make way for new ones
@@Vl7248 no not at all for every one of these machines
there are thousands of boats racing every weekend
on rivers, bays and lakes all over the world
@@radioboys8986 then you have exactly what you want. The big money wants to play with new toys.. let them. It’s spectacular
If magellan or columbus saw these, they would have a heart attack
I could understand that a boat can sail at 70%, 80%, even 90% of wind speed, but never at 300% wind speed. It's mind-blowing!!!
it´s physics, not mind-blowing drugs.
Roughly explanied, when the wind goes across the sail, it creates a low and a high pressure zone on the sail which accelerates the air around it making it faster than the actual wind speed. Works just like the wings on an airplane
@@kiruba1337false. It’s actually because of what is called “apparent wind”. Look it up
@@kiruba1337 YEP you have a constant pulling force due to the low pressure, if there were no resistance it would just KEEP accelerating. so the issue is reducing the drac to as little as possible.
My great grandfather is the only known sailor other than the captain and such on US boat Vigilant . He was on the Vigilant which beat the Valkyrie in 1893. I was able to run down his picture from the America's cup museum and compared it it known picture of him. You can look him up on the America's up database. (Well. Looks like they have moved it when they updated the web site.)
Notice how many names change in that list but only a couple never leave. Warren buffet is the man
That thing is flying
Came for a physics lessons. Left with talk of rooster tails for speed indication
Look at that baby fly!!!
Can't wait to see these boats in offshore races..... Surely it will be spectacular,... and the records tumble.
Absolutely [pirate vocabulary] beautiful! How well does it scale?
Oggi inizia lo spettacolo
Sailboats works like airplanes, they don't do what they do because they are pushed by the wind that moves below the wing or sail, they do it lifted by the lower pressure of the wind that travels close to the top surface of the wing or sail, in the case of sail, that means the the wind had to come at angle against the boat so as it sails this wind will become apparent wind at lower angle to the boat, so that wind will run on the front of the sail at lower pressure than the wind that run on the back of the sail, the difference of pressure between the front and back of the sail generate a force that pulls the boat forward, if the sail is big and rigid enough the force will pull hard enough to make the boat sails faster than the surrounding wind.
I wonder what speed record on water is only under wind power, and if these boats or any can go any faster.
I guess it would take a radical new type of design in order to really start pushing boundaries in the boat industry I suppose.
But I absolutely love these flying machines they look spectacular and very very exciting to watch.
The speed record is way faster than these AC75 boats are capable of > 65 knots... ua-cam.com/video/R4ogWm0-dzQ/v-deo.html
Radical design, for sure. Horses for courses as they say.
@@jamesaron1967 one way to go faster on water
check out ice boats
Waka Waata yup they got a new design it's called an airplane ... get some the Nuge!
someday, even cruising boats may have this tech. i can already picture 100foot ships with giant versions of this in some day in the world of tomorrow, this has to be the coolest water based mode of transport invented in the modern era-nay ever! even the thought of fully automated 20-30foot sailboats like this bringing the families and adventurers of tomorrow around the world. what a sight to see this being born!
🔥🔥🔥🔥
Lets not forget who invented this class of boat .. and all the naysayers who were raving about the catamarans
And we thought Bermuda was fantastic !!
Luna Rosa Cup and Prada Cup? I like sailing, but, I would be lucky to get into the Aqua Velva cup.
Seems like these boats are more advanced than the course they run in. Any chance someone is thinking about redesigning the course?
With their speed I think a circumnavigation around a small island would be cool.
Isn't that how the America's Cup first started out? Yeah, maybe a returned to the past with these high tech boats/airplanes.
Awesome wish I had a boat
keep testing the sailing envelope!
So how fast do they go anyway?
This is so cool. I can't wait till they introduce motorcycles to the Tour de France- it will be a great leap forward in the spoort of cycling
Still only uses the wind, bro. That's still sailing.
uses wind and moves oh so close to the water, definitely sailing, bro@@scrumpymanjack
@@albertootero1697 whatever.
Guess boats can be any shape now cause they don't even sit in water..
well, they do don't they?
180 degree turn unimaginablly fast just a second WOW! It is out of the world capability and capacity. 100 knots Really!!!
It should be a legal requirement that every video like this has at least one tripod shot of the vehicle moving SO WE CAN ACTUALLY SEE HOW FAST IT IS. Please leave your drones and dubstep at home
I love the broad Aussie accents in the British and Italian crews!!
The crews are multi national, the boats are national. Best crews available.
Anyone wondering how: it's basically a hydrofoil craft, which a known to lower drag to the point they're lightning fast.
No clickbait here. The title does not say how it’s possible to sail faster than wind speed. Kind of simple really, think how a fan blade pushes air by moving across with the angled blade, blowing a stream of air slower than the blade is moving. Now think of it in reverse. The wind blows on a rigid sail, and the boat and sail move across at a faster speed than the wind. The triangle formed can predict the approximate ratio, - direction of wind, direction of motion, and the sail.
They broke physics
how fast are they going
Just when I thought it was a great time to be a dolphin...
Crazy i heard every word
If it’s sailing at triple the wind speed then what’s pushing it along (the force)
i cant understand how you can sail faster than the wind?
The sails function like airplane wings. Instead of lifting a 100,000 pound aircraft into the the air, the air flow around the sail pushed a 16,000 pound boat across the water. There are dozens of sail boat classes that can sail faster than the wind. The AC75 happens to do it to the extreme.
Think about this, Lawrence - hold a grapefruit seed between your thumb & forefinger. Now squeeze. The seed will be shot forward totally out of proportion to the force applied. It's a question of how the force is applied.
While hydrofoils enable a sailboat to rise out of the water thus getting rid of the resistance between boat & water it's even more impressive when an iceboat on ice can sail close-hauled over 100mph in a 25 knot wind.
There is also the matter of hydrofoiling large ferry boats in use around the world for the last 40 years that rise up on their foils & speed along at 50mph.
the sails are shaped like a planes wing. They create a pressure difference. so on top of the regular wind the boat is sucked into that pressure difference and raises in speed.
Aliens, the lot of them
I realize it's just advertising, but it's very weird seeing a tire manufacture advertising on a boat...
Same deal with the aircraft manufacturer.
Saling at Triple the Wind Speed is very realistic at light wind. I measure 12 knots board speed at 4 knots wind on my hydrofoil. But my board speed becomes similar to wind speed at 30 knots. Modern kite foilers can do 4x wind speed. It is actually confusing experience to go faster than wind. Wind is 4 knots and you feel apperent wind 12 knots and you start thinking that wind is picking up but it is just your speed.
Looks like these boats are doing 45+ at 15kts of wind, very quick. Not sure how they'd do at 30kts though!
@@jg-tz4fn With 30 knots of wind, the AC75s would have to use smaller sails and/or stay home. For safety, the race has an upper limit of 21 knots of wind. If winds are higher than that they delay the race until winds die down.
When the fastest boat is just a plane without wings (in the air).
Planes aren't powered by wind though.
One wing is in the air the other in the water!? Hasn't changed in many millennia.
Actually the sail has a wing like format, they are using 2 sails combined to give it the shape of a wing
It is a new sailing dimension, but probably rough on the dolphins...slice and dice.
How much?
What direction does the wind need to be from for maximum boat speed? From the side?
As a basic rule apparent wind velocity must be perpendicular to true wind velocity for max boat speed, because that maximizes apparent wind angle, when both boat speed and true wind speed is kept constant. The optimum twa in practice is less than 1 degree off that basic rule, because apparent wind speed also matters. In light air twa is slightly smaller and in heavy air slightly larger, therefore there is a windspeed when basic rule exactly matches with zero error.
How does it go faster than the wind?
Man, this is like an example of how not to edit. Booming sound with whispers. Fast, frequent, jarring transitions. Changing interview perspective every 30 seconds. And, most of all, it doesn't fundamentally answer the question it proposes.
Why is it that we are shown 600ms second flashes instead of really being shown things
in perspective.. (rhetorical)
I'll take the old style boats any day
0:46 ah yes the ffulaffulapp a siestem
Personally, my favourite of them.
