Monitor Your Anchor and Boat Position
Set your anchor position and preferences in quick or advanced mode, then monitor your vessel and position history on the map.
View Live N2K Data
Pair Anchor Alert with the PredictWind DataHub® to monitor your boat’s NMEA 2000 network in real-time. Keep your instrument dashboard in your pocket wherever you go and anchor with confidence.
This feature requires an Anchor Alert Pro subscription or PredictWind Pro Subscription.
Works On & Off The Boat
Monitor your vessel and receive alerts onboard via the DataHub’s wifi network or head ashore and stay connected over your vessel’s existing internet connection.
The DataHub is compatible with Starlink, the Iridium GO! exec and other satellite connections to keep you connected literally anywhere on earth.
Set Up Alerts
Choose from eight alert types and customize the parameters which trigger your real-time alerts. The DataHub allows Anchor Alert to read your boat’s N2K network and alert you when conditions move outside your specified safe limits.
This feature requires an Anchor Alert Pro subscription or PredictWind Pro Subscription.
Resume Alerts
Phone battery die? Close the alert app by mistake? No worry! The Anchor App detects that an alert session is still running on the DataHub and allows you to recover and resume your previous alert session in the app.
Never Miss a Critical Alert
Apple has designated Anchor Alert notifications as critical, so they bypass your phone's Do Not Disturb, Focus and Silent Mode settings to ensure you always know when your boat is in danger.
Receive alerts when boats are too close
Keep your vessel safe and your mind at ease. Anchor Alert monitors nearby AIS targets via the DataHub, creating a safety zone around your boat (default 50m). If another vessel drifts toward your position, you’ll be alerted before it becomes a threat - while boats under power are intelligently filtered out. A closer 5m collision zone provides instant alerts if any vessel breaches your immediate perimeter, ensuring total peace of mind at anchor.
This feature requires an Anchor Alert Pro subscription or PredictWind Pro Subscription.
Save your last anchor position
Never lose your anchor again. If you're staying on anchor for days it's easy to lose your anchor position through intermittent monitoring.
The Anchor Alert app knows if you're still at the same anchorage so you can resume the previous alert session including the anchor heading and chain rode.
