You are about to relieve the OOW at the start of your watch. Under STCW A-VIII/2, what must you satisfy yourself of before formally taking over the watch?

A. Only that the vessel's position is correctly plotted on the chart

B. That you are, so far as can reasonably be ascertained, capable of carrying out watch duties effectively — and that relieving officers must not take over the watch until their vision is fully adjusted to the light conditions, among other standard handover checks

C. Only that the previous OOW has signed the deck log

D. Nothing specific — the relieving officer simply takes over at the scheduled time

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
