Murray; I put that same ladder on my M-15 #249 last summer, based on archive reading. I'm of the "no holes drilled if any way possible" school, and just added some bolt tension to the hinge for sailing, and a bungee for hauling. I've thought of adding a dowel filler under the deck lip with a dot fastener or velcro, but haven't found that necessary as yet. Oh, and I used an epoxied plywood backing plate with stainless t-nuts, again per the archives. I wanted to drill above the water line, and so drilled parallel to the lower gudgeon bolt holes. My boat has a reinforcing section panel in that area, and it was tricky to measure inside/outside to be sure to hit that. I'd say I was lucky, and would mount a bit higher if doing it again, though others might like it low for graphics placement. Call it my absolute "no holes below the water line"rule. We M-15ers have that luxury. Oh, and I used some 12v electric wire I had around to pull the plate to the ladder. Being clumsy, but persistent I don't think string would have stood the strain.

Attached to the bottom rung is a nylon strap with a snap buckle at the end. When the ladder is stored, it is folded up with the bottom rung uppermost. The nylon strap goes from the topmost rung over the top of the transom and fastens on the other side. I have not seen any pictures of how the buckle is fastened to the cockpit side of the transom. I would appreciate a description of how the buckle is fastened or any pictures of the installed buckle. I know that I can count on this most knowledgeable group to come up with an answer for me..
