The Predictor is updated every three seconds internally and the status of the predictor
is shown with [Status] as shown in the table below.
Note: The ship speed must be 0.5 kn or higher. The predictor may not be displayed
or may not work properly if the speed is lower than that value.
15.6 Anchor Watch
The anchor watch feature checks to see if your ship is drifting when it should be at rest.
To set the anchor watch:
1. Select the [Anchor Watch] page.
2. Set the alarm radius (in nautical miles) with [Drag Circle].
3. Drop the anchor then click the [Drop Anchor] button.
4. Click the [Start Anchor Watch] button to start the anchor watch.
If your vessel travels more than the distance set here, the corresponding caution is
generated.
To continue to use the anchor watch, click the [Clear Anchor] button to set the alarm
about your current position. To stop the anchor watch, click the [Stop Anchor Watch]
button. The caution is not generated even if your ship drifts more than the distance set
with [Drag Circle].
If your ship drifts more than the anchor watch setting, the Alert 495 “Anchor Watch
Setting” appears.
