Amsteel Halyard splice to shackle

[allene]

You have given me a lot to think about, thanks.

To describe my application more, the boat (built in 1955) is wood as is the mast so everything is external. The halyard is being flown off a spinnaker block and will fly an unhanked 150. We can't use spinnakers in our class but that is the only rule. The block is an antique, wood with bronze shiev. I would have replaced it but wasn't sure if I was going to use wire or rope and still not sure what I am doing is what I will end up with.

Anyway, the shackle I have is closed so I need to either put an open thimble, or as I was thinking, use the cover to allow me to not use a thimble at all. Maybe that isn't possible and I should buy a new shackle, I don't know.

I also want the cover for protection in case this halyard rubs against the headstay. This is a really unusual application and I am nervous about all aspects of it.

Perhaps I bought the wrong size LS. I will find out today when I try and make it all work.
