J/30 Class Association Forums J/30 Forum The Boat, Sails and Equipment Running halyards through sheave box

I ran them over both when I cleaned up the mast on Rhapsody. I believe the aft sheaves are there to help position the halyards inside the mast. If you have the spreader bar fix, make sure the halyards run on the correct side (fore/aft) so the halyards don't chaffe. It's been so long, I can't remember which it was, but you'll know if you got it wrong!
