Got it working 
.
Now I have a headless nmea and signalK server, giving the gps, ais and compass data. The server is running openplotter without X on a readonly filesystem. Due to the readonly fs I can just switch off the power, without risking damage to the SD card.
And for configuring it is easy to login over ssh, start the xserver and then use a VNC viewer to do a graphical setup.
If needed, I can make a small document of how I did it.
Todo: some small adjustments and get the airpressure in nmea
