Main Leech Line

I noticed my mainsail started flogging along the leech badly when I was beating into 30 knots on the third reef.

Anyway, what I did eventually was tie a small line to the leech line and tighten it to the reef clew.

What I don't understand is, why it never did this before, and why the leech line is normally only tightened at the bottom of the leech. How are you suppose to set this when reefed?

Re: main leech line

A good mainsail has a separate jam cleat for the leach line at each reef point.

Re: main leech line

It's quite surprising that your sail only has a leech line cleat at the clew. Most mains have a cleat at each reef point. Is there any way you can add them on? They certainly are necessary. I was double reefed just yesterday and had the leech line cleated tight.

I think we sailed past each other then (Sunday) near Clover Point - I got overexcited when I saw the boat name as I have your book and started hollarin' 'I HAVE YOUR BOOK' at you as we passed (much to the amusement of the three other people on board)

That's neat. I remember you well. You had the roller furling sail with the blue stripe. I don't think I would have heard you above the wind anyway, but I had my ear buds in, listening to Jackie Evancho sing some opera.

Your note here is apropos, because your main leech was fluttering, and I remember thinking that you should have tightened your leech line just a bit.

Great day for sailing. I saw 29 knots of wind and hit 14.5 knots with the chute up after turning around at William Head.

Re: main leech line

Yup, I didn't know what that weird cord hanging from the sail was until this thread I'm ashamed to say (I half thought it was a manufacturing defect). I'm looking forward to giving it a go next time out (along with my new traveller that can now be adjusted under load)

And it was a great day for sailing! I'm still getting used to sailing in higher wind speeds so it was great practice

Re: main leech line

I just tied it to the clew grommet with a smaller line using a prusik knot. I think this will work well, and I am also very confused how the sail worked fine for so long without this... Maybe the leech line got stuck from friction in the sail, but now that the sail is beginning to stretch and disintegrate it slipped.

Re: main leech line

boatalexandra,

When you replace the mainsail, one option is to have the leech line adjusting "string" led over a block at the head of the mains'l, to the clew, with drop lines, longer for the 2nd reef, shorter for the third. This has kept us from having leech line creep and flutter.

The leech of the main takes most of the stress, and wears out first.
