During normal operation:
1. Use the

available pages.
2. Press and hold the
Tack
button for 3 seconds
to reset the maximum wind speed to the current
wind speed values.
Note:
All pages except for the
Current wind
speed
page are temporary and will time-out after
8 seconds.

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.
Switching between true and apparent
wind information
You can switch the unit between displaying True or
Apparent wind information.
During normal operation:
1. Press the
True / App
button to switch between
true or apparent wind information.
• In
True
mode the indicator shown in 1 above
will be displayed.
• In
Apparent
mode the indicator shown in 2
above will be displayed.
