Ternabout, my 20-foot sloop, had halyards that were wire-to-rope and original to the boat. After 20+ years of use, they were stiff as boards. The rope section was 5/16” line and the wire around 1/16”. I looked around for replacements but couldn’t find any stock halyards the right size. After pricing custom made halyards with the wire to rope splices, I was sure that wasn’t the way to go, either.
