I actually have two storage areas, besides the boat glovebox. West Marine
sells a Chart Book and a case for it. The case is a giant, heavy plastic
ziplock with a zipper arrangement. I also use a clear ~4" tube they sell
for a lot of the other charts and paperwork and clothespins to hold stuff
from flying about.

Put it in a zip lock freezer bag and keep it out of the
sun. It will even float if your boat sinks.
