Thanks Jeff H I know you can put a sleeve on the line, just not sure how to go about it. I will investigate further, this is a winter project since I need to replace the sheeves.
A couple more problems with wire halyards is that they tebd to get little wire hooks that are hard on the hands and also when you are boosting a halyard at the mast you run out of rope and get a few feet of wire.
You can purchase wire to rpe halyards already made up to standard lenghts that are not that expensive. I bought two last year for jib halyards until I can get to the all rope lines.
