You may want to look for an offending cotter pin (key to some). My tangs from
the mast top fitting to the fore and back stays are so close to the exit of the
halyards that I have to install the cotter pins upside down (the 'head' on the
low side and the tails upward) so the tails don't chafe the halyards. Not so
bad on the forestay because there are two halyards and they are not on center,
but the backstay is centered, right over the main halyard exit. If someone
didn't split the cotter pin correctly, it could stick into where the halyard is
exiting.

Subject: Re: Stus-List Severed main halyard -- speculation?
Back when my boat was built (1990) the main halyard was made of wire and rope
with a wire to rope splice. Some time ago a previous owner changed the main
halyard to all rope. One day, while we were running downwind the main halyard
parted and down came the main. As it turns out, the design of the exit for the
main halyard at the top of the mast is made for a wire halyard so has a
different design of exit than the jib and spinnaker halyards at the front of
the mast. There are bars on either side of the halyard exits at the front that
soften the exit that don't exist at the back.
I asked the local rigging shop for suggestions for how to prevent this from
happening in the future. His answer was "You don't really race the boat so why
not go back to a wire and rope halyard?" We did and so far no problems with
halyards since.

Thanks for the ideas. I have a rigid vang so it wasn't the topping lift --
good thought though. It must be, as Andy suggested, the sheave or the exit.
I am leaning towards the latter because the cut is well below the top of the
sheave and closer to where it might exit (or possibly below). There is just a
short stub of line above the shackle.

Maybe the main halyard spent time fouled on a frayed topping lift.
My topping lift recently gave up the ghost. Before that happened I had
noticed that my main halyard and topping lift were fouled. That was easily
fixed. Later on, my mast climber (who goes all the way to the top) told me my
(wire) topping lift had a few broken strands.

I had an interesting sail last weekend to Cuttyhunk, in my 1975
C&C33-1. I was blasting downwind in 17-22 kn wind under main and poled-out
jib. The ride lasted for several hours but was interrupted when I jibed the
main (in a fairly controlled jibe). To my great surprise the jibe resulted in
the main halyard parting about 3" from the headboard shackle. The amazing
thing is that the line looks like it was cut with a sharp knife -- the core and
outer braid were perfectly lined up and the cut is square. There is no sign of
chafe. Until the mast is down, all one can do is speculate, but does anyone
care to guess what caused the line to be cut so neatly? I am baffled.
btw, Cutty Hunk this time of year and with a full moon, is beautiful
and except for two other boats (one from Hawii!) there were no other cruising
boats in the inner harbor. I had to anchor though, the town moorings were
already winterized.
Cheers, David
