I'm a sailing teacher and I couldn't have explained it any better. I use the same airplane examples. In the future, I'll spice it up, though, by building some little models, too. Will be nice to watch for my young pupils! :)
although it's important you note that the whole bernoulli's principle thing is misleading and largely misunderstood. the actual source of the movement is from the angle of incidence of the 'wing'
Don't teach them this, it's incorrect. The only thing preventing square rigged sailing vessels from sailing into the wind was their rigging not allowing the yard arms to turn far enough to trim for sailing upwind. Viking long ships can sail pretty well into the wind, even with the rigging in the way, and modern square riggers that use free standing masts without standing rigging can sail pretty deep upwind. You can see videos of both of these things here on TH-cam.
I remember watching the Curiosity Show back in the 80s in German TV as a kid. I just realized how positively ambitious it was, in terms of introducing young people to science with a playful approach. And still is! After some decades it still amazes people. Many grown ups too, it seems.

Thank you for this video. I finally understand this topic now. I've always been interested in the age of sail and even though I read explanations of how tacking worked, I never understood it. Now I finally do. And you accomplished that in 5 minutes. Excellent work.
What a great show the “Curiosity Show” was - growing up in Australia in the 70’s this show introduced science to Australian kids in a way that was interesting and fun. Me and my brothers always still remember Rob and Deane and the catchy theme song 😀
An excellent demonstration which makes the apparent paradox very clear. But it should be pointed out that square riggers can sail partially into the wind, although not as close to it as a fore and aft rig. To do it, the yard arms were hauled hard to one side or the other, so that the sails were sharply angled to the wind coming more or less from the front. The wind blowing along the front of the sail 'pulls' the sail and thus the ship forward as before. However tacking one of the giant square riggers was an exhausting process as you can imagine!
@@CuriosityShow I know! Given how long it took in real life, you'd need an hour's slot. I wasn't complaining about your very clear demonstration, just adding to the conversation. :-)

I appreciate the non-patronising, non-glitzy approach to the education of young folk... the antithesis of Sesame Street. Oh, I'd already subscribed and am enjoying watching these exceptional programmes.
I just started sailing a couple years ago with a very small lightweight boat but what really surprised me was the ability of a boat to actually sail faster than the wind and oddly across or even slightly into the wind. It has really triggered what I think is going to be a life long obsession.
I love the physics of sailing as well! What I've heard about sailing faster than the wind is this; if the wind is blowing at 3 knots and the boat picks up speed, then the wind is now blowing at 5 knots, and so on. The only limiting factor is the drag of the boat and the sails.
Some friends and I went sailing in virtual reality a little while back. They were all under the impression that it was impossible to ever sail into the wind and that you sort of "just had to wait to go the other way". I'm no sailor but knew otherwise, and so had to figure out/teach them how tacking works, based only on my understanding that it was possible and very vague grasp of the physics. Once we got it figured out, we had quite a nice time exploring around the islands. This video improved my understanding just a little, so I might go back and have another try, to see if I can get the boat moving faster.
As a kid growing up in the US during the 80s and 90s, we didn't have Curiosity Show, but we did have have Mr Wizard. As a 41 y/o I still find great pleasure and enjoyment watching both shows. We need for children's programming like this.
Genuine thank you for explaining it like this. I always just assumed the -pirates- boat crew adjusted the sails so they'd catch the wind behind them and go that way, but I never imagined the sail itself forms a plane-like wing uses positive/negative pressure to propel it forward. It must've taken a super creative/smart person to figure that out.
I grew up on a harbor, where sailing was part of life. I never realized it was confusing to so many folks. Also thanks for the many memories this brought back.
Simple genius. The piece of paper tells most of the story for me. I have no idea why this came onto my YT feed but I am glad it did. I feel smarter :) Peace
My god, this has literally blown my mind. For so many years I have not understand how boats sail into wind. I always assumed it was something to do with air circulating within the curves of the sale, but it's completely the opposite. It's how the wind hits the outside of the bend that causes it to turn and then the centre board does the rest. Incredible
Awesome. Thank you. I knew this happens but I never understood the dynamics. I am very familiar with aircraft wing dynamics but never knew how the physics were connected. Thank you so much!
For a long time people thought Viking longships couldn’t sail into the wind because of square sails set perpendicular to the keel. Just as described here. BUT it turns out that they used long rectangular sails that could be fixed to the sides of the ship by ropes at very high angles close to in line with the keel and thus could sail into the wind. We modern people had assumed they were dumb and primitive but they were quite adept at sailing any direction.
This is so interesting! I did not know this before. I like this channel, because information presented is direct and straight to the point with practical examples.
Absolutely brilliant - have never understood this before. We used to have a show like this in the UK called 'How' before everything dumbed down and children were patronised rather than taught.
This was great. I've always wondered how ships sailed against the wind. I remember watching this show as a kid but I could never remember the name, just the question mark logo. It's fantastic to see these recordings published so they aren't lost. Thank you so much.
I suspect this fellow has passed on by now but I wish he knew he just gave me some new knowledge I really enjoy. So thanks to the YT channel at least. Very cool.
I live on a lake and have watched windsurfers for years now. They cross back and forth across the same section regardless of wind direction and it always amazes me.

my God......finally this has always been a tiny nagging question in the back of my mind that only pops up when I see a sailing ship, and wonder how they get around when the wind was blowing the wrong way.....I usually forget about it and never really cared enough to seek an answer.....I never thought a crazy little show from NZ would give me the answer! these guys were brilliant
Many thanks, but the crazy little show was from Australia, South Australia to be exact, and it wasn't so little, being broadcast in 14 countries and winning the world's top award for TV for young people as well as many Australian awards. We did fim in NZ, though. - Rob
@@CuriosityShow oh well very good to know. I wish I grew up with this in the united states instead of Barney and other stupid shit. we did have Bob Ross and bill nye
Amazing that they figured this out before Bernoulli discovered the principles that make this work. I think it was a long time before anyone applied this to other things like aeroplanes, imagine if they had tried to understand why this works sooner.
The air pressure demonstration he gave is known as Bernoulli's principle and basically dictates that the higher the speed of the fluid, the less pressure it has! This principle is easy to see when carrying an umbrella on a windy day: some umbrellas will fold upwards!
It’s kind of a misconception square riggers couldn’t sail into the wind. They certainly could, when the sails were turned to the side they would act just like fore and aft rigging, the main limitation to square riggers when it comes to upwind performance was the fact the degrees the square sails could be angled were often limited by the rigging itself, and tacking was difficult and required precise coordination by the crew. Most square riggers could sail 70 degrees into the wind, which is terrible windward performance compared to fore and aft rigging, but they could still sail upwind if they absolutely needed to.
yes, if I recall, historical accounts often tell of tacking into the wind to either make short distances, or sometimes to avoid being blown into reefs and such
@@nmarbletoe8210 tacking into the wind allowed a navigator options. The progress would be slower compared to riding the winds, but it also meant risky anchorages for layover could be avoided, and it made planning the needed supplies for a voyage more predictable. Plus the crew is much less likely to mutiny if it was assured of even slow, controlled progress to a friendly port. A starving crew is an unhappy crew, after all
@@oVoidhawko yes! it was very important! now, it is true that the modern sail plan is better at tacking than anything else in history, except maybe the proa. i'm not really a sailor i just hang out in the harbor a lot
@@nmarbletoe8210 haha, I trust that means you can at least swim, right? :p On that tack, I think we can at least agree those old maritime lads were straight up ballers.
What he doesn't say is, since you are effectively increasing the speed of the wind over the sails as you start to move into the wind faster and faster, it can* actually be faster than sailing with the wind.
@@CuriosityShow I loved shows like this when I was a kid (still do) because you present the information in an easy to understand way using common terms not a load of technical jargon. I have taught many people how to use power tools, woodworking, finishing, and I never made it complex. Keep it simple stupid (KISS). Last summer a 25 year old came to me and said I should be a teacher because I explained things so well. I learned from shows like yours!
Only to a certain extent. It is impossible for a ship to sail directly head-on to the wind. That would be what's known as "In Irons," and the ship would come to a dead stop after inertia. You always have to sail across the wind, hence the zig-zagging, but how close against the true wind, how sharp an angle towards the wind, is your tack.
+Melody Reitsma My pleasure. Here in Adelaide, South Australia, we have recently saved the wonderful City of Adelaide, the oldest and most complete clipper ship in the world, which is moored at Port Adelaide. These sailing ships are fabulous, and the seamanship required to handle a square-rigger must have been astounding - not many can do it now.- Rob
How a vessel sails into the wind was finally explained to me, and I was amazed to see the cork boat actually go forward toward the straw!

Heck yeah!! Kid friendly and accurate and....it WORKS!! Been trying to demo this in my kitchen, and The Curiosity Show got me that last little ooch.
It’s kind of a misconception square riggers couldn’t sail into the wind. They certainly could, when the sails were turned to the side they would act just like fore and aft rigging, the main limitation to square riggers when it comes to upwind performance was the fact the degrees the square sails could be angled were often limited by the rigging itself, and tacking was difficult and required precise coordination by the crew. Most square riggers could sail 70 degrees into the wind, which is terrible windward performance compared to fore and aft rigging, but they could still sail upwind if they absolutely needed to.
I mean, yeah, even the model has square sails...
yes, if I recall, historical accounts often tell of tacking into the wind to either make short distances, or sometimes to avoid being blown into reefs and such
@@nmarbletoe8210 tacking into the wind allowed a navigator options. The progress would be slower compared to riding the winds, but it also meant risky anchorages for layover could be avoided, and it made planning the needed supplies for a voyage more predictable.
Plus the crew is much less likely to mutiny if it was assured of even slow, controlled progress to a friendly port. A starving crew is an unhappy crew, after all
@@oVoidhawko yes! it was very important!
now, it is true that the modern sail plan is better at tacking than anything else in history, except maybe the proa.
i'm not really a sailor i just hang out in the harbor a lot
@@nmarbletoe8210 haha, I trust that means you can at least swim, right? :p
On that tack, I think we can at least agree those old maritime lads were straight up ballers.
What he doesn't say is, since you are effectively increasing the speed of the wind over the sails as you start to move into the wind faster and faster, it can* actually be faster than sailing with the wind.
Wow.. the best video I seen on sail physics.

I always knew how to sail into the wind, never knew why...great explanation!
Many thanks - lots more at th-cam.com/users/curiosityshow - please spread the word and subscribe if you haven't - Rob
@@CuriosityShow I loved shows like this when I was a kid (still do) because you present the information in an easy to understand way using common terms not a load of technical jargon. I have taught many people how to use power tools, woodworking, finishing, and I never made it complex. Keep it simple stupid (KISS). Last summer a 25 year old came to me and said I should be a teacher because I explained things so well. I learned from shows like yours!
Excellent explanation!
Fascinating stuff!
FINALLY an explanation I understand!
Thank you :)

Wow. I has no idea that sails could propel a ship toward the wind. Thanks a million
No problem. Lots more segments like this at th-cam.com/users/curiosityshow - Rob
Only to a certain extent. It is impossible for a ship to sail directly head-on to the wind. That would be what's known as "In Irons," and the ship would come to a dead stop after inertia.
You always have to sail across the wind, hence the zig-zagging, but how close against the true wind, how sharp an angle towards the wind, is your tack.
Amazing vídeo.
Greetings from Portugal. 🇵🇹
Many thanks - give it a go yourself, and subscribe to th-cam.com/users/curiosityshow for more each week - Rob
What a great video. Thanks for the detailed demonstration
My pleasure. Lots more at th-cam.com/users/curiosityshow - Rob
Thanks for this wonderful video, it answered my question perfectly!
+Melody Reitsma My pleasure. Here in Adelaide, South Australia, we have recently saved the wonderful City of Adelaide, the oldest and most complete clipper ship in the world, which is moored at Port Adelaide. These sailing ships are fabulous, and the seamanship required to handle a square-rigger must have been astounding - not many can do it now.- Rob
+CuriosityShow I dream of going to Australia one day :)
+Melody Reitsma And you will be most welcome - lots to see and do - Rob
Very enjoyable presentation--now I understand. Thank you.
