David,
I had exactly the same problem with the new genoa halyard I installed before my trip to Bermuda last year. The outer layer of the halyard chafed through in just a couple of weeks of offshore sailing. As you noted, the chafe was a few inches above the furler swivel. The culprit seemed to be the halyard restrainer installed for my roller furling. That restrainer was what I think of as a “Harken type”, with a sheave mounted in a metal yoke that could swivel from side to side (bad description, but you can google the Harken halyard restrainer to see what I mean). In my case the halyard seemed to be chafing on the sides of the yoke as the sail moved around when sailing. More tension might have limited the chafe, but it would have also made furling more difficult. When I replaced the halyard, I also replaced the restrainer with a boom bale that spans the front of the mast and through which both of my genoa halyards can be run. So far no recurrence of the chafe, though it is still early times.

Every year since, the casing of the Maxbraid has been worn through by the end of the season. I rarely lower the sail so don’t konw how fast it is happening. I have not worried too much about it as the inner casing seems fine, but clearly there is a problem. I have had not had the mast down since I bought the boat, but two riggers have gone up and looked at it and neither could figure out what the problem was. Neither thought the sheave was the issue, but the place where the wear is occuring is about 8” above the furler swivel and roughly where the halyard enters the mast. Has anyone else had a problem like this and found a solution? Thanks- Dave S/V Aries 1990 C&C 34+ New London, CT
