1098. You are on watch and the Pilot has the conn. The Master has temporarily gone below. The Pilot orders a course change which you are certain will put the vessel into imminent danger. Which should be your initial response?

The officer of the watch must immediately countermand unsafe orders from the Pilot and promptly inform the Master, as the ship's safety remains the responsibility of the ship's officers. The officer's primary duty is to prevent immediate danger, followed by reporting the situation to the Master; log entries and alarms are secondary actions.
