Anchor Dragging Alarms

Alerts before alarms and the watch keeper’s role

Alerts before alarms and the watch keeper’s role

AnchorGuardian uses a graduated model that reflects how anchor watch actually works on a well-run vessel. The watch keeper is the first line of assessment. The captain is the escalation point. The system serves both.

Alerts

Conditions are developing. The anchor is showing early signs of movement or increased load. Anyone monitoring has the information needed to assess the situation and decide whether action is required.

ALARM

The anchor has crossed the threshold that the captain himself defined as significant. Not a generic limit but a professional judgment, set in advance, for this vessel and these conditions. When this sounds, everyone on board knows it means something.

When the alarm sounds, both crew member and captain know it is real. That confidence built across every quiet night when the system stayed appropriately silent is what makes the response immediate and certain when it is needed.

Configurable for every vessel and anchorage

Configurable for every vessel and anchorage

Because no two vessels, crews, or anchorages are identical, AnchorGuardian puts threshold control in the hands of the captain. Parameters can be set around:

Force at anchor — monitor load progressively, flagging a gradual increase in conditions early rather than only at the point of concern.
Speed of anchor movement — distinguish between slow tidal drift and the sudden acceleration that signals the anchor has broken out.
Distance of anchor movement — calibrated to the actual swing room in a specific anchorage, not a generic default.
Rate of change — how quickly conditions are evolving, because gradual change and rapid movement are different situations that deserve different responses.
Chain angle

This level of control ensures the system reflects the captain’s professional judgment rather than replacing it. Alarm thresholds can be set to match the vessel and prevailing conditions, and with historical data providing additional context, captains quickly develop confidence in the alert and alarm levels that best suit their yacht.
