SignalK distinguishes the following concepts:

Apparent wind angle, negative to port
True wind angle based on speed over ground, negative to port
True wind angle based on speed through water, negative to port
The wind direction relative to true north
The wind direction relative to magnetic north

( 
https://signalk.org/specification/1.4.0/doc/vesselsBranch.html#vesselsregexpenvironmentwindangleapparent 
, but link broken, search /vessels/<RegExp>/environment/wind/angleApparent )

I'm not sure it's all really necessary.
