Re: Mainsail halyard shackle

A halyard knot is a slip knot - how does that work as a ladder rung?

An anchor hitch is also a good knot for this purpose and can be used with high tech lines.

Re: Mainsail halyard shackle

The knot is the bottom of the triangle...or box.
It creates the bulk and stiffness.

You sort of hit on it, in your description of the Buntline. It is way more likely to jam than a halyard knot. You should be able to get a halyard knot untied. At worst, you use a spike.

Re: Mainsail halyard shackle

The halyard knot also makes for a spiffy and fast stopper knot.
Also useful for grabbing/hand holds and climbing.
Under extended heavy load i would consider it a permanent knot. Ginsu it and tie another.

Re: Mainsail halyard shackle

Maybe I'm missing something. This is what I think of as a halyard knot, and it is a slip knot. I'm not sure how it acts as a stopper or ladder or hand hold or similar. On second look, I can see it acting as a stopper knot, albeit a large and complicated one.

Re: Mainsail halyard shackle

We could very well be talking about different knots.
To me, what ive used, is in my feeble mind similar to a whipping..with something left out.
Its not promoted as i did, only as an 'ending', but it has more viable uses.
So i guess 1st thing is agree on the same knot...
Iirc, animated knots shows the halyard knot.
Another possibility is that ive been doing it all wrong...

Re: Mainsail halyard shackle

I have been using a bowline this whole time. Directly to the head of the sail. Never gave it much thought.

Looking at the dynamics of the illustrated halyard knot/hitch, I wonder if it might not be the best choice for folks like me who skip the shackle. Seems like it could twist and or chaffe the sail with the absence of a shackle.

What gives you that impression? Think itís roughly the same size knot as a bowline, with a smaller loop.

I use a bowline to tie the sheets to the Genoa, because the loop isnít size restricted. One advantage of the halyard knot is that it will cinch down on the shackle or head of the sail and take as little room at the masthead as possible. When the head of the sail is extremely close to the sheave or block, this matters. In some cases, it even requires a splice, as the neck of the splice has to enter the sheave/block.

Re: Mainsail halyard shackle

I reverse all my working lines. I specíd them longer than needed to allow resplicing. Even having done this I feel the main halyard is the one line I never,never want to fail. It would be a major headache on passage and a catastrophic event if someone is up the mast. So it gets replaced on a schedule.
This year it was replaced and went with dyneema. It has a chaff sleeve around the eyesplice and up for ~5í. At full sail both the block and splice are covered. Itís in a solid cast block. Bending metal makes it weaker. Shackle pins are weaker than the shackle. The pin gets a last twist with a pliers then a bright zip tie on passage. The end is filed to be smooth. If itís not there the sail comes down and we look. Itís yet to come down for that reason. It goes up for days and doesnít come down so this isnít an inconvenience. In weather this is one thing I donít want to worry about.

Maybe just because I havent tried it. Most of the boats I have owned had spliced eyes.

The one or two I have owned without spliced eyes seemed to be tolerant of bowlines. I am willing to give the knot a try though.
