[Public-List] Mast Sheave

[Dwayne Back]

This was a rope halyard that slipped the sheave, 7/8 if I remember right.   There are what seems like metal guides that are loose that would "tighten" the line to the sheave, but I am unsure what the actual setup is meant to be.

Thanks,

Unfortunately having a wire halyard jump its sheave is fairly common.  Since you've got to address the sheave anyway, I'd recommend that you switch to a rope halyard instead of repairing the existing one.  

Wire will eventually cut any fair leads you put up there, unless you're very careful to be head to wind when raising or lowering the main. 

With the modern ropes that are available there's no reason to keep using wire.  

We've still got a rope to wire main halyard; I'm as careful with it as we can be.  (All our other halyards are rooe)I've got a rope sheave and plan to switch to rope... After I fix the steering cables... Then there's the list of house projects ...

Unfortunately in the time I was able to address the issue the main sail was significantly damaged by wind.  Apparently the halyard slipped beside the sheave wheel and wedged in between the wheel and mast.  Looking at the mast there is plates that seem to direct the halyard line to the wheel with screw holes indicating possible guides which I am lacking.  I am curious as to whether anyone else has had this issue and the appropriate correction as I am likely going to have to buy a new main and obviously I do not want a repeat occurrence.
