Skipping a Waypoint – SeaTalk Navigators Only
If you wish to advance to the next waypoint before you have arrived
at the target waypoint, press TRACK for 1 second. The Waypoint
Advance information for the next waypoint is displayed.
Advance
While the waypoint advance alarm is sounding, Track mode is
suspended and the autopilot maintains the current boat heading.
1. Check that it is safe to turn onto the new track.
2. Press the TRACK key. This will cancel the waypoint arrival alarm
and turn the boat towards the next waypoint.
Unless the Waypoint Advance is accepted in the above manner, the
alarm will continue to sound and the current heading will be
maintained.
Dodges
Full control is still available from the keypad when the autopilot is in
Track mode.
Initiating a Dodge Manoeuvre
In track mode, dodge manoeuvres are accomplished by simply
selecting the desired course change using the course change keys
(-1, +1, -10 or +10).
Cancelling a Dodge Manoeuvre
Once the hazard has been avoided, the course change selected for
the dodge manoeuvre should be cancelled by selecting an equal
course change in the opposite direction.
Note: Provided the vessel remains within 0.1nm of track, there is no need to
steer back towards the track.
Safety
Passage making in Track mode removes the chores of compensating
for wind and tidal drift, and will aid precise navigation. However, it
is important to maintain an accurate log with regular plots.
Position Confirmation at the Start of a Passage
At the start of a passage you must always confirm the fix given by
the position transducer, using an easily identifiable fixed object.
Check for fixed positional errors and compensate for them.
