To anchor the gooseneck downhaul you need one of these cleats (available from Dwyer) that goes in the mast slot at the base of the mast. You are right about the mainsheet and blocks. That o.e. 3 part system is a little underpowered and a lot of us have upgraded to a 4 part system. The two blocks with the snap shackles are the jib/genoa sheet lead blocks. They attach through the various slots in the aluminum toerail, and can be moved more forward or aft to adjust sail twist. The Forespar branded pole is a whisker pole for the jib or genoa, a nice bonus. It is used to keep the sail from collapsing when running downwind. The "probe" goes in the sail's clew cringle and the clip attaches to a loop that should be about 3 feet up on the front of the mast. I do not recognize the custom whatsit but it probably is supposed to be used to secure something for trailering. -----Original Message----- From: montgomery_boats <montgomery_boats-bounces@mailman.xmission.com> On Behalf Of Gerry Lempicki via montgomery_boats Sent: Tuesday, March 19, 2019 6:28 PM To: montgomery_boats@mailman.xmission.com Subject: M_Boats: M17 Rigging OK, I'm learning by leaps and bounds here. I really appreciate the help. It makes more sense now that I know the opening was already lowered. So then the gooseneck would be inserted and raised up a bit in the mast...but where would that line from the gooseneck have been anchored to keep the boom down (resisting the sail and halyard pulling up)? I'll attach a couple more photos to show more.I found what I assume is the mainsheet with two blocks. I'm guessing the larger block with cam cleat attaches to the traveller on the forward cockpit sole, and the single block goes on the eye about midway on the boom. Correct? And how would the jib sheets be run back on the M17? I did find 2 separate single blocks; I'm not sure where they were used. I also have a telescoping forspar; it has what a would call a probe on one end and a clip on the other end. Gee, I'm almost ready to drop the mast again, install the halyards (I found 2), raise the mast again and hoist the sails. Then I can take real measurements for the new mast. Oh, there was also a custom whatsit in a locker (see photo). It's made from a pvc glue in coupling and two jam or V cleats; any idea what this was for?
