Thank you. Finally understand how foil on boats finally works. I kept asking and no one answer, you are the only one that explained in a simple and perfect way that a novice in sailing would understand
Like a good skipper, communication is VG. (It also helps that the young lady also lived in the Hillfoots - if they can understand, then the explanation must be good).
All this wonderful technology of foils for sailboats reminds us what an incridible genius Éric Tabarly was. This French sailor was already using foils for real ocean races decades ago !
My 1st foiler I made in 97, published in ym and yw June that year, and coincidentally hobie brought out their tricolor, very similar to mine. Then I made hydroplanes with wig, very effective
[1:02] So the reporter understood the concept of drag from the sail. But, for some reason, she wasn't able to understand THE EXACT same concept when applied to the hull and keel of the boat? So we go with friction now?
Great , but contact with water disappears which in my opinion makes it 'less sailing'. OK, you go faster and it's all explainable. But for me being in and with the water makes sailing/surfing so beautiful.
Do foils only become more efficient when they lift boats totally out the water or can they still make boats more efficient by just lifting them a little bit?
@@JS-qg1ie you can get a little bit of efficiency but you really need to lift all the way out to make a significant difference. Sails and wings produce a force forward, sideways, and a torque trying to drive the sail toward the water. A foil needs to keep the boat from tipping over, and keep it from going sideways as well as lifting the hulls up.
I can barely stand on one foot, much less surf because I lack a sense of balance. How the heck do they keep these boats from tipping over? Is there some stability built into them like aircraft and conventional yachts?
Call me when the first foiling craft does the trans Atlantic race. In the mean time, I would kill for ten minutes just as a passenger on one Foiling craft. 45 mph on water with sails.
I Know Right!... just like the earth is flat, it's nothing new. I mean everyone knows about how nasa started and what "nasa" means which is "great diciver" which can be translated to "Liars".
Are the Brits going to win back the queens cup????? My sons grandfather races the small hydrofoil loud motored boats many moons ago I think before ww2 or after.. Good luck to all sailors. My dad raced a snipe and later the Canadian made keel sailboats... so, all boats to me are interesting.. thanks for reel..
No, not likely, at least not Ocean Liner size due the fuel to weight ratio. Additionally, foiling has the issues that you can colliding with underwater obstacles like whales, logs, ice, etc. It could be very useful for smaller applications like water taxis.
Oracle Team USA -> [6:11] OF COURSE!!!!!! This team is as American as the Bayern Munich is from Munich. Why don't be honest and call things by their name? The Oracle Team, the T Mobile Team, and so on. Corporations really do love the New World Order.
density of air to water is not "1000 times" but 784 times....... its ok for common man like me to round it up to "a thousand" but its not ok if a man of science, or a man posting/representing science, to be largely inaccurate like that
It's 784. 1000 kg/m^3 (water) divided by 1.275 kg/m^3 (air)yields 784. Therefore, at sea level, air is 784 times less dense than water. Expressed in another way, a volume of air at sea level has 0.1275% of the density of the same volume of water. Just look it up.
1000 is just easier for the general public to get their heads around than 784 . It's not like anyone who actually needs to know is going to get their figures for this CNN interview.

For all of TENET's complicated plot, this is what I wanted to know most when I got back home from seeing it!
Cool! I was in room with the towing tank when I visited Southampton in June 2015
very good ! bravi

Tabarly is God.
Amen to this, Tabarly is a prophet of sailing and literally the son of Poséidon. He didn't die at sea, he just went back home.

So we go with friction now?
Does anyone have an idea on what song is playing at the end of the video?
So many Aussie and Kiwi accents in this “American team”
Seriously... wtf
Sadly, sailing is just dying in the US for multiple reason, which is sad because it's really fun.
Its what they do best
Kiwi's are the best sailors in world.
@@HaysClark what reasons?
We came second a couple America’s cup ago to the US. Last time we won, and we’ll win again! Go New Zealand!
There is no "second" in the America's Cup. :D

This is cool and scary too.
Glenn Jerome Everette Damn it. Now I want a _Moth_. I've got the entire Sea of Cortez only about 75 feet from where I'm sitting to go sail it in, too.
Curses! Foiled again. *Twirls mustache
Do foils only become more efficient when they lift boats totally out the water or can they still make boats more efficient by just lifting them a little bit?
James Stimpson My guess is as long as friction with the hull and the water doesn't happen.. But then you don't want too high or you'll get air draft
Jojo Fruji Cheers, I did think that but didn’t know. 👍

@SixGun Al I should have added. "For displacement hulls". Foils on planing hulls are a more complex topic.
I doubt it'd help much until a certain point..

No. You just have to hike(lean on the side of the boat) in order to counter the wind pushing in the opposite direction
My great grandmothers grandfather won american cup. He stands statue in kalix, sweden

Wasn't the Atlantic crossed in a foiling craft in 1980?
it would be super cool if they figured out how to supersize this technology and using it to transport cargo
So for me … let boats compete to eachother. This is something else , almost different sport.
He misspoke. He meant much less resistance per lift at 4:31
I think he said much smaller resistance
I hate how everyone acts like hydrofoils are a new thing. The navy has been testing them since the 1940s. There's nothing new about them.
Adam Gronemeier
While it's true the idea has been around for a very long time, it's only recently that they've become more efficient and practical.
Engeneer Enrico Forlanini started to work on hydrofoils around 1900. Take a look at the Piaggio P.C.7 too.
I Know Right!... just like the earth is flat, it's nothing new. I mean everyone knows about how nasa started and what "nasa" means which is "great diciver" which can be translated to "Liars".
Well, considering the long history of boats it is new.
Yes that's true , but not with competition sailing !
Southampton foilers represent!
this is the only thing from cnn i will watch
Fake news
yeah no one care about your stupid opinion let me guess you think fox new is real hahah
Stick to faux 'news' then.
You guys are fucked, CNN is actual fake news, they have faced som mics legal trouble for this too.

So are we ever going to see superfast hydrofoiling ocean liners?
the current would not be strong enough to lift a 100 ton boat
No, not likely, at least not Ocean Liner size due the fuel to weight ratio. Additionally, foiling has the issues that you can colliding with underwater obstacles like whales, logs, ice, etc. It could be very useful for smaller applications like water taxis.
4:38 What's the name of this type of boat? Thanks.
These boats are called Moths.
@@sean_lundy Thanks a lot.
@@honeybabou6119 hydro-foil boats.
@@HighAway Sorry, I meant "model", not "type". Apparently they are moths (as said in the video, silly me). Thanks anyway!
@@honeybabou6119 i thought that dude were sarcastically rude to you. haha
Wth.. is this the future like that movie WATER WORLD? That's the 1st time I seen it!
Nah... America's cup is back in New Zealand... Kiwis now hold the cup and the right to defend
We are now doing it!
Go's to school, and plays Halloween theme song
For a moment i thought the presenter was blind with a "blind stick". I thought cool... a blind presenter...
the only thing of value CNN has ever put out
When are sailboats gonna fly!?!?
But how do you carry your family in comfort on one of those??

I don't like cnn but this is actually cool
On it the subtitle. Hahehi

A lot of these boats closely resemble the one from Waterworld xD

It's not 784, it is in fact 784.3137254901960784 repeating. A man of science shouldn't round down to the closest integer!
1000 is just easier for the general public to get their heads around than 784 . It's not like anyone who actually needs to know is going to get their figures for this CNN interview.
