I’m making a simulation game where you can create a sailboat and sail around the North Sea, and this has been really helpful for giving me a better understanding of what I’m working on and what I need to simulate. Thank you!
OMG thanks a million. The instructions were crystal clear - amazing teaching skills. I read the book and saw other videos, but this video simplified the concept and made it clear.
Thank you for this! I have no boat and there is not one on my horizon. Of late I have been watching the many people who sail while making YT clips about their travels. It's a fascinating world out there!! They all speak the language of sailing and now thanks to you - I have some insight of what they are up against. Thank you so much!
I’m a volunteer teacher for my club, and your explanations are very helpful and easy to understand. I will ask my students to watch your videos. Thanks so much!
My man, this was incredibly detailed and eloquent! GREAT JOB with this explanation! I just went with a buddy of mine for the first time on his boat and this helped me a lot to understand the physics involved. Keep them coming ✌🏼
Wow thank you so much. I bought that Marineverse on Quest 2, but this has been the best tutorial without me pulling my hair. Tutorials in the game makes you wanna smash the headset
been hooked on everything sailing except real instruction because everything i've come across thus far hasn't resonated well, but you sir nailed it and i know i can learn to sail now. i hope i get someone like this on the water next spring. great work thank you
FINALLY !!!! Im an aircraft mechanic AP-IA. This my freinds is the BEST INST VIDEO EVER for explaning sailing. Wind, Hydro, Aerodynics, THIS GUY HAS IT ALL. I PROMISE. THANKS SIR.
I have been sailing for many years and have been asked many time to explain why I do things. Your teaching has given me the examples in how to clearly explain what and why I do things.
Thank you, very well explained. To have an educator that recognises people have different ways of learning right from the off is great. I was lucky enough to participate in a tall ships race many years ago. The rudiments of sailing were explained, but it was mostly necessary to just pull on lots of ropes until told to stop. Fortunately there were people who knew what they were doing there too! The similarity between a sail and an aircraft wing was something I only heard mentioned quite recently when watching a documentary on some crazy looking computerized hydrofoil racing boats which had solid sails. If only I'd heard it sooner, it would have made what was going on much less of a mystery. I also understand why we happened to do really well a little better, and why the crews of the sleek racing yachts that only just beat our ketch to the Canaries were cursing because they couldn't get the most out of them having spinnakers!
I don't sail, I would love for myself and my daughter to learn and I love watching your videos, you are very good at what you do. I hope you're going to upload more soon
Excellent. Thank you. From a physics perspective, I'd be interested to know how the keel creates lift in the opposing direction, as it doesn't change angle in relation to the bow, nor does it change shape. I would think that it would have equal pull in both directions and acts more like a stabilizer. I imagine that it could have something to do with the boat being slightly pushed sideways and the depth of the water on one side versus the other when the boat has some roll. Another interesting thing would be, when the boat has forward motion and starts to have wind build-up because of the motion, it seems that theres potential of creating a self induced no sail zone, capping the speed, how would someone adapt so they can achieve speeds faster than the real wind speed?
Two great points here! Let me see if I can answer for you: 1) You're right that the keel is symmetrical, but because sailboats often move through the water with some sideways (leeway) motion, like when you're sailing upwind, the water flows over the keel in an asymmetrical fashion. The water is actually going to move faster on the windward side of the boat, generally. So, while the lift from the sails will be on the leeward side of the boat, the keel lift vector will be on the opposite side. 2) As your boat accelerates forward, the boat starts to create its own wind, which will always come from the direction of the bow. When you put that wind direction together with the true wind direction, you get your apparent wind, which is what the sailboat will actually be utilizing. This is why you have to sheet in your sails when you start to accelerate, especially in a planing boat. The faster you go the more the wind moves "forward" and you have to sheet in more and more. As far as I know, hyper-efficient sailboats like the foiling F50s on Sail GP are able to point more upwind because of their rigid sail structure and lack of drag, but they don't accelerate to the point where they can no longer sail in a certain direction. They CAN sail faster than the true wind is blowing, due to them creating more apparent wind as they accelerate, but they can still sail anywhere outside the no-sail zone. While sailing upwind, their no-sail zone is essentially smaller because they can point more efficiently. Hope this helps!
This was such a informative helpful video for me. I'm a complete newbie and everything made good sense. I'd love more videos of sailing basics with equal attention and detail!
We really appreciate it! Will try and continually post new videos when we can. Maybe this can hold you over until then! 😂 ua-cam.com/video/o2qHa54WJP4/v-deo.html
The most clear, and precise tutorial on youtube so far... I completed three levels of sailing courses, just here to finesse my understanding. You are an excellent instructor. Will there be any upcoming theory videos like this?? 👌
The first thing to know is counter-intuitive. A boat is not pushed forward by wind behind the sail. The boat is sailed into the wind (against the wind). It is the difference between high pressure on one side of the sail and low pressure on the other side of the sail that propels the boat forward.
Nice catch! The answer is that there are a number of factors! The article below is a good one. The lift example we use isn't untrue, but it also doesn't get to the whole truth about flight. www.scientificamerican.com/article/no-one-can-explain-why-planes-stay-in-the-air/
Food for thought, to wonder what is the nature of this force. Even airplane engineers think there is uniscovered part nature of lif forces yet to discover. Victor Schauberger would probably know something abou it. He observed nature to understand. For sure there is good enought reason to start sailing :)
Is there a sweet spot between a hanging telltale and luffing? Can you measure the exact degree angle of sail in each condition and take the exact middle ground for optimal sailing efficiency? Or is the perfect efficiency spot truly at the exact borderline between luffing/not luffing while running a haul, and as soon as the telltale catches wind during a run?
There are a number of really good photo illustrations online about this! The best indicator is to use both your telltales (inside and outside) in tandem. If both are streaming, the sail is perfectly trimmed for the direction you are sailing. Depending on what you're trying to do though, there can always be variance: bow down vs. pinching

Absolutely! Newton's 3rd Law, Bernoulli, + other things. There's a lot happening. Here is a great article on the complexities of lift and how there's still much we dont know: www.scientificamerican.com/article/no-one-can-explain-why-planes-stay-in-the-air/

Oh gosh the old 'a sail is an airplane wing' thing again. As shown in the drawing, an airplane wing is 2 feet thick so the path on one side is different than the other. A sail is less than a millimeter thick so the path is the same shape and distance. This video can be helpful, in the same way that if someone taught you the sun goes around the earth you'd know to expect dawn in the morning. But it's not accurate. Just look at the explanation of thickening/pressure/speeding up. Think of the leading edge of a jib sail - it has no such thickening squishy bulb part. This really isn't even the way an airplane wing works but that's a different problem. Look if this video helps you make the right decisions sailing more power to you but I wouldn't suggest you take it too seriously as science.
@@charlesbechtel9976 oh there's a pressure diiference - absolutely. I'm in no way saying that NOTHING in the video is true. Life isn't always binary, some things are complicated. That's why i said the video can still be useful even when inaccurate.
@@markm417 Hey! We appreciate the comment. The sail works similarly to an airplane wing, not exactly like it, but to give people a reference point of something else they can compare it to, we talk about the airplane wing. It's a strong visual which aids in people remembering what's happening. I don't think we say in the video that the comparison is 1 to 1 or perfect, but the main point, that the curved shape aids in creating pressure differences, is accurate.
What's also true is that the drawing I made is of an asymmetrical airplane wing, but there are also symmetrical wings. There's more to lift than just the pressure differences, but once again, it's an "INTRO" to sailing theory.
Correct! But they both utilize similar principles, and because most people are more familiar with airplanes, comparing and contrasting methods of creating lift can be beneficial to understanding what's happening with your boat!

The greatest account for the high pressure isn’t the Brunelli effect. It’s the distance the wind traveled along the sail sides.
Bernoulli's Principle. www.google.com/search?q=bernoullis+principle&oq=bernoullis+principle&gs_lcrp=EgZjaHJvbWUyBggAEEUYOdIBCTEwNzA4ajBqOKgCCrACAQ&client=tablet-android-verizon&sourceid=chrome-mobile&ie=UTF-8
A sail begins to luff at the top first, so watch the top of the sail and steer the boat to eliminate that luff
Paraglider pilot here - I find this video oddly satisfying😅
Ha! Welcome! Now I need to go watch some paragliding vids….
The “sheet” does not refer to the sail. It is a rope. To sheet in means to pull on the rope.
What does luffing mean? I used some translators, and they give different meanings. Could you please explain this word?
Flapping in the wind, instead of having a nice full and smooth sail.
How does a plane fly upside down ?
it never does. it is rapidly tacking between two CH positions. But you see it flying upside down :D
