Just forget about your normal ideas of preserving storage
space and wasting it.
Because you are often outside of internet
range, download every single
chart for every region you might find yourself in. Get the big open water
charts, the coastal charts, the harbor and approach charts, all covering the same region. Download every available file you can.

Get all of them. Every single
