vessel heading and speed information is available.
True and Apparent wind
Wind angle, direction and speed are reported as
either 'True' or 'Apparent' wind measurements.
• True wind — True wind measurements assume
the vessel is motionless in the water. True wind
readings are calculated using Apparent Wind and
STW values.
• Apparent wind — Apparent wind is the wind felt
on deck when the vessel is in motion which is
affected by vessel angle and speed.
With the vessel tied along side, True and Apparent
wind readings should be identical.

1. Wind direction (specified using compass points)
True Wind Direction (TWD) — The compass
direction that wind would appear to be blowing
across the vessel if it was not making any way.
Apparent Wind Direction (AWD) — The
compass direction that wind would appear to be
blowing across the vessel when it is making way.

2. Wind angle (specified in degrees)
True Wind Angle (TWA) — The angle between
the TWD and the center line of the vessel.
Apparent Wind Angle (AWA) — The angle
between the AWD and the center line of the
vessel.
3. Wind speed (specified in the chosen speed units)
True Wind Speed (TWS) — The speed that the
wind would appear to be blowing across the
vessel if it was not making any way.
Apparent Wind Speed (AWS) — The speed
that the wind would appear to be blowing across
the vessel when it is making way.
Note: True Wind readings require Speed Through
Water (STW) data to be available.
