On the topic of knot vs splice: https://www.youtube.com/watch?v=bLZUfPZbU3s
Seems pretty clear cut to me ...

No doubt...A splice will nearly give you the same strength as the line, where a knot is almost half as strong.
I think the reasoning for knots on halyards is ability to retie if you happen to chafe through. Simply cut and retie. You're not going to be putting breaking loads on your halyard, so the line breaking is not the issue, chafe is.
Personally I like eye splice on halyards. I just have enough length to cut off the old chafe.
I read somewhere that some guys put axle grease on the splice and sheave before the start of a race. Sounds messy but better than chafe. I'm sure there are more opinions on this.
One of the reasons I like the fisherman's bend for halyard shackles is that there are 2 wraps around the shackle eye to spread load and chafe. An eye in the halyard only provides 1 loop and since it tends to be loose, I think can work more than a tightly tied fisherman's bend and chafe The more bearing surface, the less chafe. Check out a few boats on your dock. Those that just loop the mooring line's eye over the cleat vs. those that feed it thru and then over both horns.
The fisherman's bend is used to attach line to chain in ground tackle, so is a very strong knot. I don't think most of our boats' halyards face anything like YouTube test shows. I've never had a fisherman's bend even appear to slip and had to cut every one off because I couldn't untie it. The halyard tension on a Wyliecat is great for a 30 foot boat since the sail is essentially the size of a standard 30 footer's main and jenny.
I don't know about axle grease? It's important to match line diameter with sheave radius and size to avoid wear. And check the sheave surface to make sure it is smooth and not nicked. Sheaves wear out, too.
Sounds like a plan to me. Just got a new main. I gonna try your way.Quote:

I don't think any of the halyards come close to breaking tension.
