Re: C&C 26 wire halyard replacement
I'm coming into this thread late but I'll add my two cents anyway. We bought a 1975 38 ft C&C in 2008 which had wire halyards. The wire halyards had plenty of meat hooks and I would continually cut my hands on them. That winter we took the mast off and replaced them with the T-900, which is very low stretch. They work great, but I probably didn't need to go to that extreme of a halyard. Stayset-x would probably be plenty. You'll have to learn how to put an eye in double braid line but there are plenty of directions available.
The sheaves at the masthead were tapered for the wire so I put them on a lathe and reshaped the groove to a U shape with a rotary file. They also had worn brass bushings that I replaced. The bushings are easy to replace. A good hardware store will have them. Find the right size and push them in with a press or a vice.
I haven't had any trouble with them since.
