$WIMWV

Summary
NMEA 0183 standard Wind Speed and Angle, in relation to the vessel’s bow/centerline.

Syntax
$WIMWV,<1>,<2>,<3>,<4>,<5>*hh<CR><LF>

Fields
<1>    Wind angle, 0.0 to 359.9 degrees, in relation to the vessel’s bow/centerline, to the nearest 0.1
           degree. If the data for this field is not valid, the field will be blank.
<2>    Reference:
           R = Relative (apparent wind, as felt when standing on the moving ship)
           T = Theoretical (calculated actual wind, as though the vessel were stationary)
<3>    Wind speed, to the nearest tenth of a unit.  If the data for this field is not valid, the field will be
           blank.
<4>    Wind speed units: 
           K = km/hr M = m/s
           N = knots
           S = statute miles/hr
<5>    Status:
           A = data valid; V = data invalid
