Previous boat didn’t have a chart plotter. We used OpenCPN with a waterproof, daylight readable tablet at the helm, connected via WiFi to the hardwired pc at the nav station. The NMEA bus, AIS, Radar, and autopilot were connected and viewable. We also could download animated GRIB files on the chart. We controlled the autopilot with routes. Using TeamViewer as the connecting app, we could see the screens on any device, android, Apple, or windows. With OpenCPN’s most recent update, allowing split screen, and a refined control menu, it rivals pretty much any chartplotter.
