Leroy,
There are three side shrouds leading to the chain plates each side of the CM26. I release the front one on each side and attach both to the top of the frame. The base of the a-frame is attached to where the shrouds were connected to the forward chain plates. I then connect the main sheet (block and tackle with cam) to the bow and top of the a-frame. The two rear shrouds on each side are never disconnected. They serve as stabilizers, preventing the mast from swaying side to side any more than 3-4 feet when the mast is down close to the rear rail. The mast tightens to no sway as you raise it with the frame. After clamping the line in the cam I disconnect the forward stay and lower the mast. I have lowered the mast down on the water by myself in 3' seas and managed to target the roller in the middle of my rear rail without incident. I use the mainsheet for this because it gives me length to lower it from the cockpit and I can hold the mast with control. It was an experiment which I did by myself to see if I could handle stepping it without help. Now I do it alone all the time with confidence. I've timed the a-frame lift to 15 minutes if all goes well. The a-frame stores neatly under the cockpit.
