Wow, John- more excellent info pertaining to my boat's set-up. Thanks very much! This is all really clarifying a lot of the stuff that was clear as mud in my mind. And in your second email too. I really appreciate all of you typing these messages out to help me figure this out. Even though the guys that will be helping us have a lot of sailing experience, I don't believe they have 45 year old Montgomery set-up knowledge like this. It really helps me prepare the boat properly.

Your mainsheet block bail looks identical. Your tack reefing strap eyes and clamcleats look identical also, though mine are placed somewhat differently (closer to each other, staggered vertically, and close to mast track/aft edge of mast rather than forward more on mast). Looks like your mast has a bent mast gate opening that is below gooseneck. Mine has milled (cut out) opening that is above gooseneck. My halyard cleats are euro-style shape and placed at 90 degrees on side of mast rather that towards aft edge of mast (cleats identical to your halyard cleats were the original jib sheet cleats on my boat). The small cheek block and small clamcleat on port side of your boom are for a topping lift. The line (I'm using 3/16" single braid polyester) is fastened to the aft portion of the masthead casting, on the port side, runs down through the small cheek block, and forward to the clamcleat. That small a cheek block would not be installed for reefing the main and as Dave said the clew reefing lines for mainsail are normally on starboard side. I moved my small cheek block for topping lift aft, as it was IMO too far forward on the boom. Yours looks more aft than mine was originally, but hard to tell from close-up. My boom has two larger cheek blocks on starboard side for clew reefing lines (and had two horn cleats also, which I replaced with clamcleats). Doesn't look like yours has any of that on starboard side? So I've no idea what that eye strap type thingy on your starboard side is for. Nothing like that on my boom. Mine has a short line with spring clip attached to the backstay splitter ring, for clipping to the rear of the boom when the boat is rigged up but 'asleep'. I also use it to hold the tiller up out of the way when not sailing but using the cockpit space (at anchor, in a slip, whatever). cheers, John
