Go MusicHello,

Although the "widowmaker" reel is not generally considered ideal these days, jambing halyard sheaves is not among its many vices.   The problem is likely due to wear in either the sheave or its cheeks which allows the wire to jump off.  The cure is to replace the sheave and have a close look at the slot in the mast through which the halyard exits.   If the aluminum is eaten away (it likely is), you will have to rivet or screw bolster plates on both sides to act as guides.  Easy fix, I've done it on many yachts.

And no, you won't regret going to rope halyards (and float-testing the reel winch).

  Hello,
  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?
   
  Will a rope sheave fit in the mast head? I am considering going all rope. Maryland Marina, who has a good rigger, is recommending replacing the sheave since the bearings are probably shot and out of round and the sheave apears scored (looking at it with binoculars), and going to a wire/rope combination with a winch on the mast. They think all the current turns contributes to causing the jumping out because the lay of the wire is constantly being turned. I don't mind adding a winch as I like to raise the halyard from the mast anyway and want to do away with that dangerous and old reel halyard winch.
   
  Any thoughts appreciated.
