    Pure excellent these explanations. I've been sailing for almost 20 years and I've never received this information as clearly as I have looking at your videos.

    Hi there, nice video! Question: shouldn’t 8:20 be B, C and D as I thought the Cunningham also opens the upper leech and induces twist. I thought when close hauled one would tension the Cunningham to increase twist and thus depower as easing the vang would straight the mast, make full the sail and thus increase power.

    Hey, Yes i agree with you, depending on the boat, applying Cunningham can definitely induce twist. We'll call this an omission. The boomvang and mainsheet, however have a more pronounced effect on leech tension and twist.

    Try adding shorter telltales that are much closer to the jib's luff, like shown in Photo 2 here: gentrysailing.com/pdf-magazines/9-Achieving-Proper-Balance.pdf Also Figures #2 and #3 here: gentrysailing.com/pdf-magazines/10-Sailing-to-Windward.pdf These telltales are much better because they warn of impending luff and stall rather than signal that luff and stall has happened.

    I want to know what it is called when you lower the sail and tie it. It's called trim. That's not what you are saying.

    When you lower the sail part of the way and tie it, it's called "Reefing". Not covered in my presentation here but definitely a valid strategy for depowering your sail.

    I kept looking up trimming but I knew that wasn't it. I knew that wasn't what it was called. Thank you for understanding what I meant. So cool and Happy Sailing!

    The only part I disagree with is the depowering. It's the short shift and the extra trim to go even faster. But safer.

    2:12 - "the leech telltales are a little bit less important..."? - It is a steady, pervasive myth. ))) Sail 'quality' should not be determined by incoming flow, but by outgoing (deflected)...

    I agree that leech tell tales are important, but i stand by what I said about the order if importance. You can't helm a boat upwind only looking at your leech telltale, you can looking at the luff tickers.

    @@howarthsailing I think that when not alone, the helmsman should work with the jib tickers which are easier to read so it's faster to react. The team will manage the main-to-jib balance in order to have both tickers and telltale flying. What do you think about that ?
