Waterproof charts that are easily folded, and sharp in detail? Yes, it is possible. Maptech is the company that has accomplished this, and you are the lucky recipient of their product R&D.
The two-sided chart opens to a manageable 24" x 36", and is a compilation of the most up-to-date NOAA Charts available as of 04.28.99. It even show what type of fish is prevalent in what area.
Great for planning a trip to this area, or if you just want a reminder that you have been to some of the nicest cruising grounds (grounds?) around.
