Brilliant video, best and most clear explanation I’ve heard on this subject. Thank you

Thanks. I finally understood the concept as simple as it may be.

Thank you, very clearly explained. Please make more, as us beginners really benefit.

Great info. Thanks ⛵️😎

The first part of the  video is good if you assume that the wind will shift back the other way on the same upwind. However, in dinghy racing with legs that last only 6 minutes or so, one might only see one shift per upwind. In that circumstance, the boat on the left side of the course when the left shift happens actually benefits over the "lifted" boat on the right. The reason is that the left shift moves the starboard-tack lay-line farther away from the boat on the right, while the port tack lay line moves closer to the boat on the left side of the beat. The right call is still for the starboard tack boat to tack on the header. But they get a huge gain over the l lifted port-tack boat when they do.
Furthermore, the author does not properly draw the lines of equivalence (ladder rungs) starting about 4 minutes in. The lines of equivalence should shift with the wind. If you do that, you can see that the left-side boat moves farther up the ladder rungs as the wind shifts left.

Great visual. This is the explanation I've been looking for!

Really good video

Much Obliged sir, thanks. 👌👌

Great explanation thanks

thanks sir plz keep helping through ur videos

I have never sailed nor had the desire to. I only googled how opposing winds affect sail boats to use as an analogy for life. Man did I get that plus some. The more I learned the more I researched and the more it connected. Much appreciated.

This excellent. Thank you

Great vid.

Top tip👌

In order to reduce number of tacks, do you wait before tacking when experiencing a header? On a blustery night we could be tacking five or six times and spending the extra time with so many tacks. Is it worth it tacking on every header?

Huh. I couldn’t get more than half way through unfortunately. At minute 4: “In a left shift, the port tack is favored.”  That seems to be the opposite of what I understood to be true about ladder rungs. Or around minute 2, when you say the red boat is further from a mark after a left shift... but that doesn’t look true according to ladder rungs because the red boat is on the left course and therefore now a higher ladder. ... This is going to take some time for me to chew on. Thanks for the thought provoking video
