Re: Mainsail halyard shackle

Let's see, sailed from St Pete to Norfolk, SF to Newport beach 3 times, SD to French Polynesia and back to Hawaii, SF to Kona and all the sailing in between with tied on halyards. Yeah, I think knots work just fine for halyards.

Re: Mainsail halyard shackle

Halyard knot on double braid is a no brainer.

Not so simple with high tech like dyneema - no way one should just throw in a typical knot like a bowline on those.

Re: Mainsail halyard shackle

I have been using a 'halyard knot' for all four, for over 15 years. We have a main, jib, and two spinnaker wing halyards. Way back when, I replaced all the original wire-to-rope halyards with T-900. I remove them and wash and end-for-end each one, every few years. No problems.
Our main halyard shackle is like the second one in the OP's post.

While you could tie the halyard directly to the headboard, I was suggesting you tie it to the shackle.

Re: Mainsail halyard shackle

Mark has a point about splicing used double braid when you end-for-end. If your halyards run inside the mast, you would not be able to presplice both ends and be able to pass the new halyard through the mast fittings.

My halyards have an in-line loop at the bitter end (can use multiple passes with whipping line). I pull the internally run halyards at the end of the season, replacing them with 1/8 Dacron braid messengers. That gets the halyards out of the weather during the winter and you can wash the them to remove dirt and salt and keep the halyards soft. I have not had a chafe problem.

Re: Mainsail halyard shackle

IMHO All the above comments have good merit.
1. The simplest is a Halyard knot weather tied to a shackle or direct to the headboard.
2. Splicing in new double braid or dyneema style line is very easy like a cup of coffee, to splice older double braid can be difficult once it looses its flexibility.
3. It is not a bad idea reverse - end for end you halyards from time to time, but if you are getting chafing on your lines then there are other issues that need to be addressed.

Yup, but as you said, those are simple as brewing coffee. So no problem, there is an easy solution, one way of the other. No excuse no to trim the end of the halyard.

Re: Mainsail halyard shackle

Honestly, this is my first time seeing mention of a halyard knot. Currently I'm using a buntline hitch on my halyards to attach the shackle, with the plan to just cut it off and retie if needed since the knot only takes up a few inches of line. It's compact enough that chafe really isn't an issue.

Any merits of the halyard knot over a buntline hitch, or vice versa?

Back to the OP - I had the second shackle in your pic for a while. The previous owner had them attached with bowlines. I wanted less chance for chafe and a little more room before the knot hit the masthead (I have a little 22' trailer sailer), so I used a compact knot.

Re: Mainsail halyard shackle

Side note on the halyard knot...
Can also make a long one to be used as a ladder rung for dinghy or boat...ok barefooted.
