Excellent.

Thank you!! 🎉just started sailing, wasn’t sure what to do with this line.

👍

Thanks for explaining..

Although concise, it's too much to take in as a beginner.

I personally find the "accelerated air -> depression/slowed air -> pressure" explanation counter-intuitive. The cause and effect seems to be the other way around: the wind is blowing against the sail, the sail blocks the air from escaping, thus air pressure builds up. On the leeward side the sail blocks the air from coming in (the one trapped windward's), thus depression builds up (perhaps then the air from a higher pressure region rushes in, resulting in an accelerated air flow).

Nice explanation, thanks. Only one important matter was missing though. You shouldn't apply backstay without increasing main luff tension because draft in mainsail moves aft which is just the opposite of what we need. First of all is to apply Cunningham tension BEFORE applying more backstay tension.

Very nice...one recommendation...please turn up the volume at your end. With my speakers at 100% I still had to use CCs. Thanks.

Can you reef with backstay tension on?

Can you do one on the downhaul, its missing from your series? Cheers.

At 5:28 it says that as the wind speed increases, the apparent wind moves forward. Not quite right, it moves aft. As boat speed increases then the apparent wind moves forward. I think....

Great explanation- but what does Roach mean?? Do you mean Leech - the aft side of the sail???

Thank you! It is the first time I understood how to do such a maneuver.

Some of your diagrams are back-to- front eg. 1:57 vs 2:15. Boat pointing left/ boat pointing right ?

Excellent explanation on how to use the Cunningham, thank you.

No volumn... can't hear anything... Fair Winds...

Cool explanation! Here on a 15yr old YT video 🙃

Excellent explanation. Tks

Amazing video

3:57

So you never got to sail trimming the main and head together?

Having take a one inch strip off and exactly parallel with the (old) luff, when that snagged on a spreader, I prefer the outside Gybe. Thanks for the tip. I must learn to tolerate testosterone more and rub shoulders with some racers to pick up more of these things.

Thank you Alexander! Good balance of easy learning and more in depth (physics) explanations. Much appreciated!

Excellent video! Very well done and explained. Thank you.

Before the gybe, sheet the main all the way out. And don't pull it across during the gybe. It won't impact at all. The sail will luff before reaching the end of the sheet and the spreaders, if you are very alee before it swings. When the winds are high, you want spinnaker to fill on the new side before the main swings. This will be the end of broaching on the gybe.

How would you install a Cunningham on a inmast furler?

14 years later and this video’s instruction is timeless!! Thanks.

The definition of the "I" measurement is incorrect, albeit only slightly

Brilliant tutorial and so important

Chad

So am I right to assume that loosening the backstay tension will flatten the upper half of the sail?

What? No peel?

Poor english comprehension ... the wind is higher the higher up the mast? No the wind is (stronger) in general at altitude

Gracias

Awesomeness

Awesome!

these are amazing videos, thank you so much~ I was absolutely baffled about what the "ropes" on the boom is supposed to do or what they're even called

Excellent clear explanations.

Eye opener to new beginner sailor

Good video but misuses the term 'roach' when he's actually talking generically about the 'leech'. The leech is the aft edge of any sail. Main sails are not usually a perfect triangle and any additional area aft the straight line from the head to the clew is called the roach.

Thank you M

I really like these videos and the punchline of this video is spot on, but there are a couple of BIG AND IMPORTANT ERRORS in this video. (1) The first is his statement that tensioning the backstay on a fractional boat will not increase headstay tension, when in fact it will add a lot of tension to the headstay. This is something that's easy to measure, is related to headstay 'sag', and sailmakers use adjustment in the amount of headstay sag to make jibs more versatile. (2) The second is his statement that tensioning the backstay on a masthead boat will not bend the mast, when in fact how much it'll bend the mast depends on the mast and the backstay adjuster. I'm currently racing on a 37-foot masthead boat that gets about 4 columns (~24 inches) of mastbend when the backstay is on fully and we reduce bend from the maximum by playing the checkstays.

Fantastic breakdown, thanks.

Never have I heard such a clear explanation for these things. You're a great teacher

Great explanation, thank you. It’s hard for me to understand how curving back the mast actually flattens the sails, though, I know that’s what it does. It seems like that would create more of a camber.

To anyone watching this, Please ignore this explanation it is very far off from the true physics of what’s going on, and will not deepen your understanding of driving w/o a rudder. It’s all about how a tightly trimmed mainsail rounds you up into the wind due to the fact that your center of effort has been moved aft, and vice versa with a jib

Excellent video mate, thanks for that!

I need a Cunningham. I need a boat first, but after I get one: Bam! Cunningham!

Good video but confused by the use of "arm that is pulling the boat." Did you mean the sheet that is attached to the boom and traveller?

Really lie your videos ! Very useful ! Thanks a lot :)
