Thanks for the comments
The Boat Network on this boat is from a fairly new generation B&G Vulcan Chart plotter .
The TCP GPSD thing was strange to me as well. On a previous boat, and the old Pi3 I used TCP, and it took me a long time to get the android to work on this boat, because I set it TCP, and when it wouldn't work, I changes things until it did work....with some help from an IT friend. I don't really know what the differences are.
I did try the USB GPS via signal K and it also never worked. I never tried the WiFi via signal K purely because of time constraints. I had plenty time at home to try the USB GPS though. At the moment the USB GPS works sort of. it shows satellites in the air, but no position or time data , which is another reason I think the Pi PSU is a problem
This weekend past I was on the boat again , and noticed a strange problem with the chart plotter. When the Pi was on, the plotter was having difficulties with GPS fix's. As soon as the Pi was powered off, the problem went away. Owner has never seen the problem before either. I have a theory that the 12v to 5v 5amp switch mode supply is possibly killing the RF in the vicinity of the Pi.
I will go assemble a linear regulator for the Pi (which is what I had in the Pi3, but only 1A capacity) and see if it makes any difference. I went with the switch mode for size and efficiency, but I know they are noisy. Never thought it would be this much of a problem.
