Laptop chart plotting is so much easier to use than messing around with chart plotters and entered waypoints and routes! Point and click is all you need.
More or less any laptop will do.
Set your laptop up for minimum power draw. Use a separate screen (we now have a Currys Essentials 16" TV that has a VGA input, runs on 12 volts), and switch the laptop screen off. Get a wireless keyboard and mouse that runs off USB. Serial interface USB adapter for NMEA input/output, plus a second one if you have AIS engine. You keep the screen switched off except when you need it.
We use OpenCPN with some legitimate C-Map NT+ charts, and worldwide (dubious origin, but no reason to suppose inaccurate) charts.
That is exactly how my waterproof RC80 works
