We have had a problem this year with the halyards jumping the sheave and jamming. Finally this weekend after having to miss the 3rd race day we hauled Tim to the masthead.
He tied himself off and replaced both jib and main sheaves.
Back in the cockpit we examined the sheaves he's taken off and saw that they had very shallow "U" grooves which were allowing the 8mm vectran easily to jump the groove.
The new sheaves have a deep "V" groove. Problem solved? We sure hope so.

Derek, are you running internal halyard with single sheaves at the top or the original 4 sheave setup?

There is a divider between the pairs of sheaves. When I was redoing the masthead (and found the divider missing), I easily fabricated one that was taller than the original and made it impossible for the halyards to either jump sheaves or jam.

If you need an extra, I have one. I went to internal halyards with single sheaves front and back. I also have extra wire sheaves. I had this problem trying to run rope halyards with the stock wire sheaves.
