In reply to: Steve M-32 Pyxis 's message, "Rope Halyards" on - Tuesday - 11/ 6/07 - 1:49am

Have been meaning to post the same question for days as am considering a similar upgrade this winter.

I have photos and measurements for the wire sheave currently in use on Murre's main and mizzen (will get and post later in week). It's solid bronze but it's "v grooved" for the 5/32nd (or 3/16th?) wire and much too narrow to accommodate the 3/8ths line necessary for an all-rope halyard.

I've worked on the main masthead a bunch. There ain't much to the box, and as the sheave load is borne mainly by the stainless mast head fitting, and as the box would need to be enlarged only by roughly 3/16th of an inch, it “feels” like a pretty straightforward swap.

But then again, if I’m wrong, the whole thing comes crashing down…

So I’m with you … anyone else done this? :)

Last year at the sailboat show I asked the question to the right person who told me to use only rope instead of rope and wire because he said the wire is brutal on wood. So find a place where you can hook up a block single, double or triple depend on how many ropes you want to run and forget about the wire and rope thing he said. So that's what I did for mizzen mast to run the topping lift and the halyard on a doubble and I'll do the same thing for the main halyard.
Hope this will help you gentleman. So you can do it in the same way the jib and spinnaker halyard are being used. If you need to see it I could sent you pictures of how I did the one on the TAYGETA mizzen mast.
Ardian.
