Sleipner (aka Side-Thrust) bow thruster support?
Sleipner (maker of bow thrusters) uses a CAN network to communicate between the control panel and the thruster. Their wiring diagram shows a network that looks a lot like a NMEA 2000 network, and in fact, their "s-link" documentation says:
Main advantages include:
- Round, compact and waterproof plugs with unique keying to avoid faulty hookup
- Unlimited number of commands or information transfer on a single cable
- Proprietary Sleipner commands, but built 100% on NMEA 2000 standards
I have a pi with a CAN hat on my network. I think I'll see if any PGNs come over the wire from the thruster.

How important is galvanic isolation?
I'm considering using a Pi with a CAN hat that also provides power. However, that hat doesn't provide galvanic isolation. But that may not be important because it does provide power, so the only ground that the Pi will see is from the NMEA network.

Basically, the Pi will only be attached to the NMEA 2k network for power and data, and will not be connected to any other power source.
Or is this a bad idea? If so, I'll use NMEA 2k-to-ethernet bridge, and connect the Pi and the bridge to my ship's wifi hotspot.
