bunks and they work well. I would suggest that you make up a small 4 part block and tackle about the size you would expect to see on a Sabot or small dinghy and install it between the pad eye and your top line. I use one with a jam cleat. That way you can release it and get in and out easy. Make the line on the blocks long enough to completely drop the top of the canvas all the way down. It takes some adjustments but it will work. I would make the cloth at least a foot above the cushion and the full length of the bunk and lace the top line through grommets places along the top. The lee cloths you buy from someplace like West Marine are always short and either your feet fall out or your pillow ends up sliding out. I have used two methods for the attachment of the bottom. I have used a 1.5 X 1/4 inch strip of teak wood and sandwiched the cloth between it and the bunk and screwed it down. That's fine if you're not going to remove it. You just lay the cloth under the bunk when not in use. That's what I do for the bunk we use most of the time at sea. The other way is to put grommets in the bottom also and drill small holes at the bottom of the fiddle that keeps the cushion from sliding out. Then I loop a small line through the holes and grommets along the bottom and tie it off at the end. I use that method on the other bunk when I have extra crew and need to remove it easily. Tying the cloth to the hand rails on the overhead is a PITA and makes getting in and out slow and painful. Good luck with your project.
