What should a navigator look for when assessing if an anchor is dragging?

When assessing if an anchor is dragging, a navigator should focus on their position relative to the drag circle. The drag circle is the area around the anchor point where the vessel can swing while remaining anchored. If the vessel moves outside this drag circle, it indicates that the anchor may not be holding effectively, which suggests that it is dragging.

Monitoring the position of the vessel in relation to this circle is crucial, as it gives a clear indication of whether the anchor is maintaining its grip on the seabed. A change in position, especially if it's towards the shoreline or into deeper water, could signify that the anchor is not holding, prompting the need for reevaluation or a potential re-anchor.

While the depth of the water, weather patterns, and type of anchor used can play roles in the overall anchoring situation, they do not provide the direct and immediate indication of whether the anchor is dragging. The drag circle specifically addresses the performance of the anchor at that moment, making it the most relevant factor to assess.
