What is the purpose of anchor signals and the anchor watch concept?

• A. To monitor weather only.
• B. To determine optimal anchor type.
• C. To alert to risk around anchoring and ensure safe operation while at anchor.
• D. To coordinate with other vessels about anchoring positions.

Answer: (C)

The main idea here is that anchoring requires ongoing vigilance and clear signaling to reduce risk. Anchor signals help other vessels know you’re at anchor and to keep clear, while the anchor watch is the dedicated effort to monitor your own vessel and surroundings so you can act before problems develop.

Having an anchor watch means someone is continuously looking out for changes that could affect safety—wind shifts, waves, current, tidal movement, or a drifting anchor—and for approaching traffic or hazards around your anchored vessel. This vigilance helps detect dragging early, so you can adjust the anchor, increase or shorten scope, or depart and re-anchor if conditions worsen. It also supports safe operation at night or in restricted visibility by ensuring you display appropriate signals to indicate you’re anchored and by maintaining awareness of other vessels that might come close.

So, the purpose is to alert to risk around anchoring and ensure safe operation while at anchor. The other options miss the core point: weather monitoring alone, selecting an anchor type, or coordinating anchorage with others do not capture the safety focus of signaling and watchkeeping while anchored.
