I have two pipe berths that are the only bedding on board my 22ft Bolger sloop. The dimensions were taken off of Phil's plans. They are 24" x 6'2". I'm 5'11" 210lbs and they fit me fine. I used 1 1/2" galvanized pipe and had a local welder bend and weld the ends together into a continous loop to give me a good strong frame. I painted the pipe with spray primer and several coats of enamel. In the nine years they've been aboard there is no sign of corrosion. I had a local upholestry maker sew the canvas using 10 oz. canvas for the cot and 13 oz. canvas as a 1 1/2" border to support the grommets and prevent ripping. The cots have a vinyl binding sewn in all the way around to protect the raw edges. The grommets are spaced at 3 inches apart. They are laced onto the cots using 3/8 dacron line in half hitches all the way around with one continous line that is tied off where they meet. The berths are attached to the sides of the hull by epoxying small blocks with concave grooves at the top to support the pipes. I put polyester straps over the blocks to hold the pipes in place. These straps are just to hold the pipe in place and let the blocks take the weight. The inside of the berths are supported from the cabin ceiling by two adjustable straps. This way you can adjust the cot to the heel of the boat.They also act like lee cloths. The cots stay folded up and out of the way until needed. They fold down quickly to sleep or rest on. You can store your bedding material and clothing behind them when not in use. I've spent up to three weeks on board using these cots. You could make them a little wider for more comfort if need be.
