His hatches were similar to how one closes a roll-top dry bag with fastex buckles... Ralph Diaz wrote: That form of closure is pretty much how Feathercraft hatches have closed for a decade ... Another form of closure appears in the new Pouch single. Its back deck opens wide so that you can insert the full frame into the skin (instead of the traditional way of inserting frame halves and then extending the frame inside the skin). But instead of using velcro flaps and zippers the way other models that are now using this approach (various Nautiraids and the new Klepper Alulite) to close the rear deck, Pouch seems to be borrowing a page from Voyageur dry bags. The closure consists of two beaded edges across which you slide a slotted round bar to seal the edges together. Ralph Hoehn: This deck closure was actually inspired by the system used on the "Delphin" folding dinghy, built after the war at MTW in Rostock on the Baltic. Some of the Pouch guys have been in this business a long time :-). (The same set-up is also in use for attaching awnings to campers, incidentally.) The system is remarkably effective due to the fact that the greater the pressure on the deck -- from breakers crashing down on it like last weekend, for example -- the tighter the beads are forced against each other and against the inside of the slit tubing and the more effectively they seal. In effect you have the double security of a labyrinth seal and a compression seal. Ralph C.
