3.1 Using Track mode
Note: You can only use Track mode if you have connected the
autopilot to a suitable navigation system providing SeaTalk or
NMEA navigation information.
The autopilot system can receive track information from either:
• a SeaTalk navigation instrument or chartplotter (see page 50 for
information on connecting to SeaTalk), or
• a non-SeaTalk navigation system transmitting data in the
NMEA 0183 format (see page 51 for information on connecting
NMEA equipment)
In Track mode, the autopilot maintains a track between waypoints
created on the navigation system. The autopilot makes any course
changes necessary to keep your boat on track, automatically
compensating for tidal streams and leeway.
Selecting Track mode
CAUTION:
When you enter Track mode, the autopilot will bring the boat
onto the track in a controlled way. The closer the boat is to the
correct heading and track, the quicker the autopilot will settle the
boat onto the new course. To avoid an unexpected turn,
approximately align the boat with the required track before
entering Track mode.
To select Track mode:
1. Start with the autopilot in Auto mode.
2. Press

direction the boat will turn to reach this waypoint.
4. Check that it is safe for the boat to turn onto the new course.
