What's your hull number? I have #38, also a 1974 M17. Some things have no doubt been changed on my boat by previous owners, and by me since I got her, but I'm happy to share specifics of my '74 rigging if you have specific questions. Re the masthead, I don't know if my sheaves where changed out from original wire-halyard ones, but I imagine they must have been. She came with all-rope halyards. They use the full width of the sheaves, and the sheaves use the full width of the masthead casting, but there is no significant binding or excess friction. Both halyards are same size, green (main) to starboard and red (jib) to port, I would say they are 5/16. Main sheet is 3/8" and I like it that fat, smoother on the sheaves under tension, easer on the hands when pulling against lots of tension. Mine came with a 3-turn mainsheet block setup, but with the mid-boom sheeting of the early M17's that is inadequate purchase in strong winds. I have changed mine to 4-turn setup. Luckily my boat came with two traveler blocks, one all ready to go for the 4-turn setup, so I just had to buy a two-sheave block for the boom. Came with original 80% and 150% jibs with nice fat soft old style 3/8" sheets. I am using 5/16" for my new furling jib. Most everything else is 3/16", either existing or that I have upgraded or installed - outhaul, reefing lines, furling line, etc. So far all the above is double braid polyester. For my topping lift I'm using 3/16" single braid polyester, which is a bit thinner and lighter than 3/16" double braid polyester. My topping lift is fastened at masthead, runs through small cheek block near aft end of boom on port side, and then forward to small clam-cleat with fairlead on port side of boom. The cleat is roughly opposite where my clew reefing line cleats are on starboard side of boom. This puts topping lift control handy from forward portion of cockpit, same location you would be working with reefing lines, and halyards if led to cockpit. I've seen some topping lifts with control point in very inconvenient locations (like a cleat a ways up on the mast, or some setup at aft end of boom). Not recommended...if you need to adjust the topping lift you have to move away from tiller and the rest of your control lines to a potentially less safe location (cabin top if cleat on mast, aft end of cockpit if on end of boom). cheers, John On 03/19/2019 05:56 AM, Gerry Lempicki via montgomery_boats 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
