Deck General · Anchoring — Dragging
A reliable way to detect that the anchor is dragging is to:
- AWatch the radar antenna
- BTake and monitor bearings of fixed objects (and ranges), checking for a changing position✓ Correct
- CSound the whistle
- DCheck the fuel level
Explanation
An anchor watch fixes the vessel and monitors bearings/ranges of charted fixed objects (or a GPS anchor-watch alarm and the lead line). A steady drift in bearings or increasing distance from the let-go position signals dragging—pay out more scope or re-anchor.
Authority: Bowditch; anchor-watch practice
