      Has anyone replaced the sheaves on the mizzen halyard? I think that when I used the halyard to pull the fuel tank I may have overloaded it. Each time I raise the sail it makes a horrible squealing noise. I don’t know what to tell the yard that I need, I guess they should know. I would like to make it a short trip to the cherry picker and it would be best if I had the part in hand when I get there.

      Linus,
      I replaced mine with Shaefer 62-018.  These sheaves are a little wide for the mizzen sheave box.  I had a friend put them on his lathe and narrow them to a hair under 1/2″.  This was the closest fit I could find in 2003 to the existing sheaves.  You could probably bet them custom fabricated.  I used Rig-Rite for my main mast sheaves, but others have had difficulty working with them.  There's outfit others have had success with.  I can't remember the name that company other than it had “sheave” in the name.
