I spent the summer in the Chesapeake leaving Naples, Fl mid May and returning this mid October. The most valuable Navigation/Planning Aid was charting software from Italy called Aquamap. ...
Mind you, it only runs on the iOS platform which would be an iPad, which makes a welcome ancillary addition to your normal MFD. However one word of caution, the GPS in the iPad may not give you the necessary accuracy to navigate the ICW, as mine did not. You may need a remotely located GPS.
AquaMap runs on Android devices, too. No issues with GPS accuracy; our Samsung tablets always seem to be at least as accurate as our installed plotter/GPS.
