Paper towel unrolling?
One thing to think about re paper towel holders. Unless you have a way to apply some friction to the roll of towels, they will unroll in a seaway. I solved the problem by making my own towel holder from a dowel and a couple of pieces of lightweight decorative chain. The chain attaches to the bulkhead and holds the roll against the bulkhead just enough to keep it from unrolling without interfering with towel sheet removal when needed.
