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!
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!
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!
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
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
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?? 👌
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
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! 😂 ruclips.net/video/o2qHa54WJP4/видео.html
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
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 :)

Whats the game called?
What's the name of the game? Can't wait for this
Name?
I want to play this simulation!
Link to the game?
Great video
Best explanaition on this topic on youtube right now
I'm just getting into the sailing community and learning and this was the best instruction I have heard! Wonderful job! Please make more videos!
We love to hear it, we have some in the works!

What a great story, and we're jealous! Sounds like a ton of fun. Thanks for watching 🤙

Many thanks for this lesson !! No one is explaining like you do !!!! 🎉🎉
I so appreciate it!

🙌💪Anything to help people get out there and more confident on the water! Thanks for the kind words!

😂
YOU TOOK THE TIME TO TEACH I JUST WANT YOU TO KNOW I AM GREATFUL
🤙
One of the clearest explanations of a complex topic. Wish we could delete a lot of the other videos on RUclips that talk gibberish.
Means a lot!
Awesome. Great lesson. Can't wait to get into sailing
Thanks!

Outstanding video. Thanks
Clear explanation! Thank you.
great explanation
Amazing explanation, best on youtube.
Super helpful. I’ve been at a sailing camp for a week, and only now I understand how it actually works. Thank you.
Yo! Thanks so much for the compliment and so stoked this helped!
The greatest account for the high pressure isn’t the Brunelli effect. It’s the distance the wind traveled along the sail sides.
This video helped me so much. Thank you.
So great to hear!
BEST class ever! thank you

@@sailinghickamharbor260 Awesome, thank you!
What does luffing mean? I used some translators, and they give different meanings. Could you please explain this word?
What about planes flying upside down? Lift is mysterious force

@@organic7771 The mystery makes it fun!
Paraglider pilot here - I find this video oddly satisfying😅
Ha! Welcome! Now I need to go watch some paragliding vids….
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
