Halyard to wichard shackle knot

[geem]

Nothing wrong with that providing your halyards are considerably over specified, as a bowline reduces line strength a more than a halyard knot, and a lot more than a splice.
Almost certainly they will be well over specified on a cruising boat, but worth bearing in mind.

Halyard knot on the shackle is a simpler solution if you are regularly removing the halyard from the sail.

We remove our 10mm dyneema mainsail halyard after every sail. It's been the same halyard for 37,000nm. I like the bowline as it moves the halyard on the sheeve slightly each time. We have cut the end off a couple of times to remove wear, on the old stretches mainsail. It has yet to occur on the current Vectran mainsail as its only done 5000nm

10mm dynema would comfortably meet the description of “over specified” I suspect!

But easy on the hands. Anything less is painful

I’d also want to know what’s causing that amount of chafe…

As it's at the end, Luff too long or has stretched would be the obvious answers.

I'd be surprised if you have room for a halyard knot in the space of the Witchard shackle, but you could change the shackle.

Why not splice? It will be smaller and less palatable to whatever is hungry at the top of your mast.

We have exactly that Wichard shackle and a dyneema halyard and there’s plenty of room for a halyard knot on ours.

We’ve got 12mm. I never worry about it breaking. It’s easy on the hands though.

We have 10mm Marlow racing dyneema. I never worry about it breaking either
