Question 520Deck Safety70% to pass
A seaman is reported missing in the morning and was last seen after coming off the mid-watch. Which type of turn would you use to return to the track-line steamed during the night?
AI Explanation
The correct answer is A) Williamson turn.
The Williamson turn is a maneuver used to return to the track-line steamed during the night when a person is reported missing. It involves turning the vessel 180 degrees and then returning along the reciprocal (opposite) course, which allows the vessel to retrace its path and search the area where the person was last seen.
The other options are incorrect because: B) a 180-degree turn would not necessarily return the vessel to the previous track-line, C) the Anderson turn is used for different purposes, and D) the racetrack pattern is a more general search pattern, not specifically for returning to the previous track-line.
