At a risk of teaching you to suck eggs!
A couple of questions
Have you read https://openplotter.readthedocs.io/en/latest/
If you are around Felixstowe or Harwich you obviously will have strong ais signals.
Are you using the internal patch aerial or an external aerial?
Are you able to see the connections on the SignalK app webpage?
I don’t have a Moitessier Hat, my SignalK connection is shown as OpenPlotter SDR AIS, I also don’t know if you need to calibrate the Moitessier Hat AIS as you do with usb SDR.
Are you getting all the other data from the hat?
I use a usb SDR but haven’t been able to test it yet with my rpi4, OpenPlotter2 and the latest SDR VHF app as I live a long way from the Essex coast, that I know so well. But did have ais working last season on my rpi3b+ with a homemade dipole aerial at about 2m off the deck with a range, depending on the vessel, of up to 5 miles or so.
