I have a Raymarine SeaTalk network with a SeaTalk-NMEA converter. I
know I have wind speed and relative direction (relative to the bow)
and water temperature among other things of no particular interest. My
chartplotter calculates true wind direction and I believe puts it back
on the network.

I'll do some snooping and research and see if I can identify the
specific sentences.
