Anchor Alarm - The anchor guard for your boat
Get alerted as soon as your ship aborts.

Set the radius and click on Start to start the anchor alarm.
As soon as your ship leaves the radius, your device alerts you with an unmistakable alarm tone.
In addition, you can move the monitored area and correct it to the nearest meter.
The location history of the boat is recorded and can be seen from the small points.

With our remote monitoring feature, you can connect two devices together.
The sender remains on the boat while you are on land.
As soon as the sender leaves the area you will be alerted on the way.
(stable internet connection required)

With our anchorage search, you can search for anchorages in your area where other crews have anchored before. Try this module for free for 3 days!

No audible alarm.

When I get an alarm, my phone vibrates and I get a visual notice. But nothing audible. When I set my alarm clock, I get an audible. So my iPhone is working ok.

No audible warning

Great alarm that goes off by showing you on the screen which makes it useless for overnight. Imagine waking up to seeing "Ships Afloat!" On the screen but no idea how long it's been In that mode
