While you are on watch, you learn that a crewman has not been seen on board for the past three hours. Which type of turn is best in this man-overboard situation?

Correct Answer: Option A — Scharnow

A crewmember missing for three hours represents a delayed man overboard scenario. The Scharnow turn is specifically engineered for this situation, directing the vessel back along its exact reciprocal wake to retrace the trackline steamed during the missing period.
