Once again my main halyard has jumped out of the aft sheave and wedged
itself between the mast and the sheave. This is getting ridiculous! What
solutions have others devised for this problem. I think one of the
problems is that the halyard comes down the front fo the mast, goes round
a turning sheave, then through a fixed eye on the cabin top to a
reel halyard (widow maker) winch. Does anyone else have this arrangement?
Was this standard on early boats?</blockquote><br>

I'm pretty sure it wasn't standard. Our boats are the same vintage - '66
- and mine has a single, large phenolic (!) sheave at the masthead
held by a stainless through-bolt with an aluminum sleeve around it acting
as a bearing. I don't know if it was original, but the sheave was
also held between two aluminium plates which probably were intended to
stabilize it and help keep the wire from jumping out. The sheave groove
is sized for wire with a wire rope combination halyard. When I had the
mast down a couple of years ago I thought about going with a different
sheave and all-rope halyard. Decided not to because the current rig
didn't show wear and it wasn't jumping out, so I just replace the
halyards with new wire rope. Rope will fit; I know of folks who
have done it using the new Stetson thin halyard lines.<br>
<br>
My rig goes to a winch on the mast and I've had no problem with it.<br>
<br>
I know some people replaced the single sheave with two smaller one
as you describe, so that is probably what happened in your
case.<br>
<br>
