I've decided to replace the running
rigging myself, starting with the halyards. Before I'm hoisted up the mast, I would like to have new sheaves in hand to replace the old. Does anyone know what size sheaves will fit on the mast of an 1984 Ericson 30+? Can I replace old wire sheaves with sheaves for 7/16"
lines? What is the width x ID x OD of the present sheaves? Or are they all so different for these boat I have to look first?
