The quickest type of turn to recover a MOB is which maneuver?

• A. Round turn
• B. Williamson turn
• C. S-turn
• D. Figure eight

Answer: (A)

The quickest way to recover a MOB is to close the distance with a tight, direct turn toward the person and sail a small circular path around them. This round turn creates the fastest, shortest route back to the MOB because it uses a small turning radius and minimizes detour time, letting you come alongside quickly.

In contrast, the Williamson turn is a larger, broader maneuver designed to realign with the original course and bring the MOB to a favorable position behind or abeam the vessel; it takes more time and distance. The S-turn and figure eight are search patterns that spread out the vessel’s path and involve multiple course changes, which slows the return when speed of recovery is the priority.
