Almanac, Environmental, and On-boat Data

The chartplotter must be connected to the peripheral devices listed below to capture the data shown 

on the wind speed graph.

Apparent Wind Shows wind direction data based on the flow 

of air experienced while on a boat in motion. 

This is the Apparent Wind Angle, which is 

calculated in reference to the bow of the boat, 

and is represented in degrees port or degrees 

starboard.

A wind sensor.

True Wind

Shows wind direction data based on the 

flow of air experienced while on a stationary 

boat. This is the True Wind Angle, which is 

calculated in reference to the bow of the boat, 

and is represented in degrees port or degrees 

starboard. For the most accurate data, the 

Wind Speed Source setting should be set to 

).

A wind sensor and a speed sensor; or a wind 

sensor and a GPS antenna.

Ground Wind Shows wind direction data based on the flow 

of air experienced while on shore. This is 

the Ground Wind Angle, which is calculated 

in reference to north, and is represented in 

degrees clockwise. North can be true north, 

magnetic north, or grid north, depending upon 

the configuration of the Heading reference 

 

A wind sensor, a water-speed sensor, a 

heading sensor, and a GPS antenna; or a 

wind sensor and a GPS antenna; or a wind 

sensor, a water-speed sensor, and a heading 

sensor.

2.  Select the type of wind direction data included on the graph (Apparent Wind, true Wind, or 

Ground Wind).

The chartplotter must be connected to a water-temperature sensor or a temperature-capable 

transducer, to capture the data shown on the water temperature graph. The chartplotter must be 

connected to an air-temperature sensor to capture the data shown on the air temperature graph.
If you have turned on and configured the water temperature alarm (

2.  Select the type of temperature information included on the graph (Air temp or Water temp).

The chartplotter must be connected to a barometric-pressure sensor to capture the data shown on the 

atmospheric pressure graph.
