"The original sheaves were grooved for wire/rope halyards. I’m replacing my original halyards with all-rope Novabraid Argus,"
Randy, The original masthead sheaves on my 78 30 mk1, handle both wire AND rope. Same with the other C&Cs of the same age in our marina who switched to rope halyards over the years. The mast head sheaves have a dual groove design. The wire sits in a narrow slot at the bottom and the rope sits on top of that. The sheaves on the bottom are rope since the wire normally never reaches them. Unless the sheaves are in bad shape you likely don't need to replace them. Just attach the new rope to the old halyards and pull them through. All the boats around have spent their lives in fresh water so the sheaves were in good shape. Depending on your boat I would inspect them. Roy 78 C&C 30 Mark 1
