The yacht is due to anchor in a popular bay that is already crowded with other vessels at anchor. What additional considerations apply compared to anchoring in an empty bay?

A. Crowded anchorages are always too dangerous to use and should be avoided entirely

B. Allowing sufficient swinging room relative to neighbouring vessels (considering different scope/chain lengths and vessel sizes), checking the anchor position and depth carefully before dropping, communicating with nearby vessels if proximity is a concern, and maintaining a more attentive anchor watch given the higher risk of close-quarters situations if vessels swing differently

C. None — anchoring procedure is identical regardless of how many other vessels are present

D. Only the size of your own anchor matters

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

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

C. 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

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