Small addition:
I guess you need to enable the SignalK to NMEA 0183 on the Pi4 (Openplotter).
For GPS RMC should be sufficient.
But I have no idea if there is a plugin that converts back SignalK AIS data to 0183.
But if you have the NMEA data available on your Pi3 it would be easy to configure an additional SocketReader in AvNav to get the data directly from the Pi3, port 10110. You yould even limit this to AIS data by setting up a filter there (assuming you route the position data via SK on Pi3->SK on Pi4->plugin->0183->AvNav).
