Sounds like you're gonna be cruising around the Chesapeake so the first place to start is the Maptech paper chart kit for the Chesapreake Bay. This also comes with a chart CD (for PC) for the same region that lets you:
1. Plan weekend trip routes
2. Print out the "maps" & routes for the trip.
3. Use on board as a chart plotter if you have a laptop and GPS you can attach.
or buy it here online for $90.
