Set and Drift: See description below.
Wind: Wind (True or North) speed (kn or m/s) and
direction are displayed. Note that true wind is wind
relative to own ship heading. For further details, see
section 15.8 Wind Sensor.
Depth below trans: Depth from hull at bow and aft to
bottom. A depth alert value may be entered to alert you
to
Temperature: Water surface temperature.
Water current: Tide at current position.
AIS targets: Status of AIS data.
Set and drift:
Check the Manual box to manually set speed and course of drift.
Note that you can choose manual drift only if there are no automatic sources for SOG and COG. In other words, you
have neither a dual-axis log nor any position receiver available.
Angle = Difference between heading and COG
Drift = Speed component of the drift vector
Set = Course component of the drift vector
Vector defined by (SOG and COG) is equal to vector sum of vectors defined by (SPD and HDG) and (set and drift).
