We made them at home
Tim, it was not that bad. Since the boat was in Florida last winter and we live in New England, we had to make molds scaling the small drawings provided by Beneteau and we cut them from standard sheets. Once cut, saw them and threaded an elastic around the perimeter. The V-berth sheet is very easy to place starting from the front angle. Placing the aft cabin sheet requires some technique starting from the port front end and sliding it under the cushions counterclockwise. The good thing is that once in place, they remain there for the duration of the cruise. If you want, I could e-mail you a picture of the molds. In the meanwhile, this one illustrates the V-berth at work.
