I prefer the Map Tech chart books though they are not waterproof. I keep them in a flat, purpose designed, clear zipper bag. They are about $140 for the entire Fl. West Coast and the Keys out to the Dry Tortugas. Still, Waterproof Charts 33E is a must. The chart book is essentially two sets of charts, large scale for basic navigation and small scale for greater detail like in and out of check points, wilderness waterway and Florida Bay. These books also come with a CD to load on a laptop and selected charts can be printed onto waterproof paper. Pages are 16 x 21. Dave
