A concise ChartPlotter/Navigator. A cross-platform ship-borne GUI application supporting * GPS/GPDS Postition Input * BSB Raster Chart Display * S57 Vector ENChart Display * AIS Input Decoding * Waypoint Autopilot Navigation

CAN Boat provides NMEA 2000 and NMEA 0183 utilities. It contains a NMEA 2000 PGN decoder and can read and write N2K messages. It is not meant as an end-user tool but as a discovery mechanism for delving into NMEA 2000 networks.

With BBN OS you can build a central boat computer. BBN OS is free and open source. It is based on commonly used community supported open source projects such as SignalK, PyPilot, OpenCPN, and others. BBN OS graphical user interface will let you build a cockpit front-end to all functionality of the OS from chartplotting, dashboards, weather, etc.
