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. (by canboat)

Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

I live on a boat, any way to pull GPS data from dishy?
You need to submit a feature request to the OpenCPN developers -- https://github.com/OpenCPN/OpenCPN/issues -- Starlink provides location data in a proprietary undocumented interface. People have figured it though, developed sample code and documented it -- https://github.com/sparky8512/starlink-grpc-tools/blob/main/starlink_grpc.py#L154 It shouldn't be that hard to add Starlink support to OpenCPN but the developers may need Starlink hardware for code development and testing or they may need an active tester capable of running code from github.

Sailing Nerds: I need to learn about boat electronics...
Start with NMEA protocol specification documents. NMEA2000 physical layer is just CAN, really. There's an open source project already started to dissect the packets here: https://github.com/canboat/canboat/ . The wiki for that project https://github.com/canboat/canboat/wiki might help with getting started.
What are some alternatives?
When comparing OpenCPN and canboat you can also consider the following projects:
flipperzero-gps - Flipper Zero application for NMEA 0183 serial GPS modules.
Vanchor - An open source trolling motor. Features Hold heading, Hold Position, AutoPilot (NMEA APB & GPX). It still needs a lot of work but it's functional.
inav - INAV: Navigation-enabled flight control software
lysmarine_gen - 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.
