In Sally Oak just after the bridge on the right from thown, was a guy who had bought some old army bridge pontoons made out of marinply, he sold one to me for 25 quid, I made a two birth boat out of it, with a small cooking stove, and a porta potty, I had just 3 ft to make a deck with, covered it with a frame and plywood and canvas, painted it blue and white, sold it for 150.pounds, it was 12 ft x 6 ft and 1.5 ft deep, I was going to put two together and make one long boat, but the guy had sold the lot with in three weeks, and I could'nt find any more. there could have been a good business if I had stayed with it...J2..this was back in 1963..
