While at anchor watch, what should you be doing beyond simply confirming the anchor light is on and the vessel looks stationary?

A. Nothing further is required once the anchor is down and holding

B. Continually monitor the vessel's position with regular fixes compared against the plotted drag circle, swing circle, and available visual references — especially as wind or current increases

C. Only re-check position if another vessel reports a concern

D. Checks are only necessary every four hours regardless of conditions

A. The tidal height at the time of transit to confirm sufficient under-keel clearance

B. The yacht's fuel consumption for that leg

C. The colour of the seabed shown on the chart

D. Only the distance to the next waypoint

A. Assess the situation against the planned route and charted depths, take action to maintain safe water, and inform the Master if there is any doubt

B. Ignore it — ECDIS alarms are frequently false and can be left running

C. Switch the ECDIS to standby mode and navigate by GPS position alone

D. Acknowledge and silence the alarm immediately so it does not distract the helmsman
