Anchor Alert - How to set Alerts

Use your boat's GPS, wind and depth instruments connected via NMEA2000 / N2K to the DataHub to set precise alerts in Anchor Alert

Written by Matt Crockett

With Anchor Alert Pro, you can set real-time alerts based on the N2K / NMEA2000 data received by the DataHub from your boat's instruments when connected and powered on.

Using Anchor Alert Free, alerts for Drag and Swing are available based on your mobile device's internal GPS; all other alerts require Anchor Alert Pro.

Anchor Alert Real-Time Alerts

Anchor Alert includes real-time alerts for:

  • Anchor Drag and Anchor Swing angle tolerance

  • The Anchor Scope Ratio, based on depth and wind speed ranges to chain rode length.

  • Wind Speed, Wind Gust and True Wind Direction

  • Tidal Depth - minimum and maximum depth.

  • AIS Alerts

How to set Anchor Alerts

By default, after the initial setup of Anchor Alert, alerts for anchor drag and swing are enabled and set to Ready. These alerts will activate when you start an anchor monitoring session.

How to configure additional alerts in Anchor Alert ready for use during anchor monitoring:

  1. Tap the Alerts icon in the bottom centre of the screen.

  2. Tap the alert to be set.

  3. Set the desired alert tolerance using the slider.

  4. Tap the switch at the top right of the screen to enable the alert (blue).

  5. Tap Save in the top right of the screen.


Returning to the main Alerts page, the Alert status will be set to Ready. Ready alerts are set to On status when an anchor monitoring session is started.

Important Note: To disable alerts in Anchor Alert your device must be connected to DataHub Wi-Fi before you disable and save the alert.
