Default True "true wind" & the Raymarine ST60, or other

The Raymarine ST60 wind instrument uses the masthead windvane and
anamometer for apparent wind. It uses the SOW from the Tridata paddle
wheel and the COG from the autopilot to compute true wind.
No gps input needed.

That will not account for set and drift. It will give you true wind
relative to the boat but not true wind. relative to the mark you are trying
to get to.
