P17 Wind Shift, Head or Lift

Indicates changes in the wind against a compass heading.

Spotting these wind changes is the key to fast sailing upwind.

The system automatically detects the mean wind direction by

averaging over a time period of 2 minutes to 60 minutes (this

time period can be changed in setup). However, to manually overide this

automatic calculation and set the mean wind direction:

1. If a Wind Transmitter is included in your Micronet system then simply

press the button; (the current wind direction is stored as the

mean wind direction and displayed for 5 seconds during which time

the and buttons may be used to adjust the value.)

If the mean wind direction changes, press again.

2. If you do not have a Wind Transmitter included, sail close hauled and

press the button then tack and, once close hauled, press the

button again.

If the mean wind direction changes then the instrument may be

updated press and holding the button while sailing on port tack,

the button while sailing on starboard tack or the button

while head to wind.

See Raymarine’s “Using wind shifts to your advantage” sheet for further

information.
