Wind Hold

You can set the autopilot to maintain a specific bearing relative to the current wind angle. Your device must be
connected to a NMEA 2000 or NMEA 0183 compatible wind sensor to perform a wind hold or a wind-based tack
or gybe.

With the wind hold engaged, select Options > Wind Hold Type.
The wind hold type changes from Apparent to True, or vice versa.
Engaging Wind Hold
Before you can engage wind hold, you must connect a NMEA 2000 wind sensor to the autopilot.
Although a NMEA 2000 wind sensor is preferred, you can connect a NMEA 0183 wind sensor to the autopilot to
use wind hold.
