Simply putting canopies on dinghies would have saved a lot of chaps, I reckon...never understood why they didn't.

Nine man dinghy , at Maryport, inflated ready to be lashed to deck of the "Two sisters"
They did, but when? I thought we had them but maybe confused, as I bought a R.A.F surplus one, for my boat after the war. Seem to remember a story of a a canopied dinghy being overturned once in a rough sea and the crew 'walking round' it inside to right it. Also seem to remember being told that as the floor, sides, and bottom were also inflated to insulate, as well as provide buoyancy.The body heat of seven men inside would prevent frost bite, even in the coldest weather. Was it called the Beaufort dinghy ? Any one know the true facts ? A figment of my imagination?
