MWV - Wind speed and angle (PAS 102)
When the reference field is set to relative, data is provided giving the wind angle in relation to the
vessel’s heading and wind speed, both relative to the moving vessel.
When the reference field is set to true, data is provided giving the wind angle relative to the
vessel’s heading and wind speed, both with reference to the moving water. True wind is the vector
sum of the relative apparent wind vector and the vessel’s velocity vector along the heading line of
the vessel. If represents the wind at the vessel if it were stationary relative to the water and
heading in the same direction.
