Gerry: The masthead sheeves will have been made for wire to rope halyards - what was 'all the rage' back when the boat was built. Wire was used to reduce stretch. For the main halyard use 1/4" line. For the jib use 5/16" line. Below is a link that will download a rigging spec sheet hosted on the MSOGphotosite.com that may assist you. John Manfredi put this together for a newer build boat so some things are different. http://msogphotosite.com/Scripts/Information/downloaddocument.php?id=199 Anything else let the group know! :: Dave Scobie :: M17 #375 SWEET PEA - m17-375.com :: M6'8" #650 :: SV SWALLOW - sv-swallow.com On Tue, Mar 19, 2019, 5:58 AM Gerry Lempicki via montgomery_boats < montgomery_boats@mailman.xmission.com> wrote:
Hi everyone, I bought a 1974 M17 over the winter. It needs some work to be ready to go. I’m figuring some things out, but I am confused about how the running rigging was originally run and set up. And actually what size/material was used too. The sheaves in the masthead have fairly small grooves. It doesn’t appear that I got any halyards or lines with the boat. I see the rigging instructions for the M-15; is there anything similar out there for the M-17? I’ve had no luck searching. Or a list of materials needed to replace all running rigging? Thanks for any input on this. Gerry
