True Wind Gauge
This gauge uses needles to indicate the
true wind speed and direction relative to
north. The long needle points to the wind
speed, and the short needle points to the
wind direction. There is also a digital
readout at the bottom.
To view historical, true wind speed data, right click the gauge. A graph will appear
as shown. To return to the True Wind gauge, right click the graph.
Pitch and Roll Gauge
This gauge uses arrows to indicate pitch and roll. The
average angle of pitch and the average angle of roll is
displayed digitally in degrees.
NOTE: For pitch and roll values to be completely accurate in
a boat, the sensor would need to be installed at the vessel’s
center of gravity—at the waterline. However this is not
recommended because it would interfere with GPS and
weather readings. Remember that the higher the sensor is
above the waterline, the greater the error in the pitch and roll
readouts.
Compass
The Compass displays the true wind direction, the
apparent wind direction, and the heading. No historical
data is collected.
• Apparent wind direction is indicated by a black/white
needle and a black/white digital readout on the left of
the gauge. The port and starboard indicators (P and S)
always appear regardless of the compass orientation.
• True wind direction is indicated by a red/green needle
and a red digital readout on the right of the gauge.
• Heading is displayed as a blue arrow in the center of the gauge and indicates
the direction that the vehicle/vessel is moving. The heading is also digitally
displayed in the lower center in blue.
• Port and Starboard Indicators appear when the Compass is orientated in the
Front/Bow Up mode. A letter “P” representing Port or an “S” representing
Starboard will be displayed to the right of both the true wind direction and the
apparent wind direction digits. The letters reference where the wind is coming
from relative to the front of the vehicle/bow of the vessel.
