About OpenPlotter

OpenPlotter is a navigational aid for small and medium-length boats. It is available as ready-made Raspberry OS images or can be installed in parts on a Debian-based Linux system. It bundles OpenCPN for chart plotting, AvNav for browser-based charts on other devices, and XyGrib for GRIB weather files.

It connects to NMEA 0183, NMEA 2000 and Seatalk 1 networks, uses Signal K for data exchange, and offers a Wi-Fi access point, headless access and custom instrument dashboards.
