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.

Subject: Stus-List 34+ genoa halyard
Several years ago, I replace the wire/rope genoa halyard on my 34+ with 3/8”
Maxbraid. 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
