OK end of the road for me.
For anyone who may be interested. I set up a fresh instal of the OP2 Image including SignalK
I allowed the Pi to instal updates
I then installed the SKSim plugin.
I also installed a physical USB GPS and setup an SK connection for it.
With GPS connection enabled I got SK paths in the dashboard and I also got NMEA into OpenCPN on port 10110
With SKSim running I saw SK paths in the dashboard but no NMEA sentences into OpenCPN
Seems to me its a SignalK issue
I dont know how SK paths are translated into NMEA 0183 but it seems that although SK will route incoming NMEA from a serial port and concurrently create SK paths , it will not create an NMEA sentence from a SK path generated by a simulator or route an NMEA sentence if its sent over TCP.
If anyone has any evidence to contradict then Im all ears otherwise. I give up
