I was like "this is good info..."until I saw that floppy. Any "UPDATED 21st century data"?

Jeffrey 1957 - 7 years ago

Great video,thank you.....Cheers.Jeffrey

If one will disregard the explanation of how a wing works with the air flow, which is still used today in sailing classes , then the rest is good info still to today.

Faci Alexander - 7 years ago

Go and measure th distance on each side of the sail please. You may find out that the equal time theory does not hold up.

For fun on the water go to boatingfriendslist.com....Thanks

WOW, great info here... but I took a trip on the wayback machine to my 6th grade computer class at https://youtu.be/TttqFylquFs?t=6m6s

It's a basic lesson, but it isn't for basic people. It's great. Thanks.

You are a great teacher. I am greatful for the tutoring me. This was exactly what I learned in my first Sailing Lesson. Thank you, once more you have help me understand the physics of sailing.

Robo Robot - 7 years ago

Based on the comments, apparently this guy didn't explain the physics of the sail very well. I'd maybe take it with a grain of salt.

Ajmal Mian - 8 years ago

waste of time .you may be a great sailor but you can't teach so give up

James N - 8 years ago

dude this video is like 30 years old, I highly doubt he's sailing, the guy may be dead at this point

Excellent video!

Sailing Miss Lone Star - 9 years ago

Great video! We are selling our power boat and switching to sail later next year. We are currently cruising the Caribbean and I always love catching up with your channel! https://youtu.be/-QpAMvKhFzU

As a beginner to sailing, almost 10 minutes of my life wasted. This is not for beginners at all. Why do i need to know about a racing main sail!!!
Sorry, but very disappointing.

Jon Knight - 8 years ago

+Liofa whatever, but I'm not the only person that wasted time on this.

Liofa - 8 years ago

I don't even sail, but I understood it... Maybe you're just not that smart?

Calvin Smith - 9 years ago

The explanation at 0:48 is total nonsense.

"The parted particles have to meet at the other end..."

No they don't. They don't meet. And furthermore, the air on both sides travels exactly the same distance. Actually, the air touching the sail doesn't really move at all.

Andin Briwel - 8 years ago

You should create a video explaining this, especially the part about how air in wind is not moving.

Human Footprint - 9 years ago

Awesome!: what a pro! thanks for this great vid series. :):)!

John Beasley - 9 years ago

yep, the program came on floppy disks, I have had a copy of this video for about 20 years, North Sails

That's a computer? Damn! History is a relevant subject.

stevedeb5960 - 9 years ago

Excellent instructional video, very helpful. Thanks for post :-).

Mike Albanese - 9 years ago

Too bad this is far from the basics. From a total beginners point of view 90% of the sailing jargon and terms went over this boys head. A basic sailing video should explain sailing terms and then how to apply them. This video missed that for me anyway. Guess I need a basic sailing video.

number9express - 9 years ago

Someone needs to wake up Bernoulli from his slumber and tell him he's full of it, I guess.

Hugh Jass - 10 years ago

I had no idea how old this video was until I saw them feeding the floppy disk into the computer. Wow.

Andrew White - 7 years ago

I was just thinking the exact same thing! Hello Floppy Disk at 6:06

onelonleyfarmer - 7 years ago

holy cow 5 1/4 floppy!!

Matt - 7 years ago

ROFL yeah i am only 30 and when i seen that i was like hmmm yeah this video is old....

Zoltán Szabados - 9 years ago

about the mid 1980's

Peter Worsley - 10 years ago

Your explanation of how a "wing" works is wrong. The theory about the airflows travelling different distances and "having to meet" at the trailing edge has been discredited. Think about it, how then could an aerobatic plane with a symmetrical wing section fly? see: http://www.grc.nasa.gov/WWW/k-12/airplane/wrong1.html

Leonard Milcin - 7 years ago

Not actually right. The thrust is created by the air being deflected from its normal course. The thrust is maximised when the deflection is organized (so all air is being deflected in roughly the same direction and the vectors add instead of subtracting -- nullifying the thrust).

It is important to understand that the volume of the air deflected behind the sail can be much greater than the volume of air deflected before the sail. The sail works like a scoop -- scooping some air and moving it aside -- but this is only a fraction of the potential. The rest is generated by the low pressure behind the sail. That's why correct positioning of genoa is so important, not because it moves a lot of air by itself, but because it assists the main sail in moving the air behind it in an organized flow.

mytube001 - 7 years ago

That has nothing to do with it. How a wing works has been known for at least a century. This video is old, but not that old... :)

Liofa - 8 years ago

To be fair this film was made about 30 years ago...

Shahana Perveen - 8 years ago

and no modern jet fighter would fly lol

MISTERComaToes - 8 years ago

+Peter Worsley No, no no little pixies lift an airplanes wing by flying across the surfaces passing very quickly over and under the wing! If your way was true they would never meet on the far side of the wing! Pixie's get very lonely if separated and they rush across the wing on either side to meet at the trailing edge. It's Orville and Wilbur's greatest discovery!

Bor the Wolf - 9 years ago

+John Luftenberg Yes, and according to the BS theory an airplane cannot fly upside down. Please tell those brave Airforce Pilots not to fly upside down in a dog fight, the theory says it is impossible!

John Luftenberg - 10 years ago

+John Luftenberg Though in fairness, airplane wings and boat sails is an apples to oranges comparison since a wing is a solid airfoil and gets at least some of its lift from deflecting the incoming airstream downwards.

John Luftenberg - 10 years ago

Absolutely correct, and my thoughts exactly. Amazing how much misinformation gets passed along as if it were factual.

Buck Turgidson - 10 years ago

56 seconds in and it's clear the narrator has no idea about aerodynamics!

cptCory - 10 years ago

Finally a "Sailing Basics" video that actually is instructive. Thumbs up! :D

Lovre Peović - 10 years ago

There are a ton of wrong statements about aerodynamics of the keel.

spelunkerd - 10 years ago

I came back to this video because I don't quite understand the principle of how heeling causes the keel to act like a sail underwater, allowing the boat to move to windward. How does that effect differ from weather helm, where automatic turning into the wind is from the center of effort being aft of the center of resistance?

Très bonne vidéo ! merci

jimloesel - 11 years ago

This is a really nicely put together video explaining sail shape. I liked the way you explained that a deep sail is like low gear and a flat sail is high gear, I never heard it put that way and I found that comment really helpful.
