Another Idea
Alan: What I did was just change my jib halyard to rope, and left main halyard with the wire / rope combination that it originally came with. We had a problem similar to the one Ed described. We had to wrap wire around the cleat to the jib, and then up to the downhaul cleat under the boom, and then back to the jib cleat, to get rid of the extra wire, when we use our drifter that goes all the way up to the masthead. When we converted to all rope, this solved this problem. But, it created another one. We couldn't get the halyard tight enough since we didn't have a jib winch. I added one and don't know how I did without it. A benefit of an all rope jib halyard is it doesn't get stuck on the spreaders when you are using it. I originally ordered a stronger line something like Spectra, but it was too stiff to coil-up when the sail was up. I had to return it to West Marine, and get something softer, and less strong. (That's probably when I realized that I needed a jib halyard winch). Anyhow, there is a spacer between the sheaves at the masthead, and I remade this spacer from thin stainless steel. I think that the original one may have been about 1/8 inch thick aluminum. The one that I made was probably between .035 and .050 thick stainless steel. I made the replacement sheaves from delrin, but you can probably buy them. I don't have any problem with the wire halyard for the main. It's strong, and offers less wind resistance than a rope main halyard would. Remember that the main halyard runs down the front of the mast. Aldo
