J/30 Class Association Forums J/30 Forum The Boat, Sails and Equipment Replacing spin halyard sheave

I had the sheave box off today on Rhapsody. It is not a simple answer because there are multiple sheaves fore and aft. The forward sheaves are the same diameter as the main halyard sheaves. On Rhapsody these are riveted in. The aft sheaves provide separation of the halyards through the center of the mast, hence different sizes and locations. I left the camera on the boat but will post pictures that I took today when I return tomorrow night.
