Interesting idea. But don't the hulls normally need to breathe, so as to avoid expanding in the hot sun?
I would think that something like this would have a designed max pressure and therefore have a relief valve built in to control over pressurizing. It would solve the problem with my Prindle 18 hulls taking on a little bit of water every time out, but I'd probably have to have a 12 volt air pump to keep a steady pressure.
