What turn is the ideal method in reduced visibility?

• A. The Williamson turn
• B. The Hoyt turn
• C. The Anderson turn
• D. The Scharnow turn

Answer: (A)

In reduced visibility, the priority is to get back to the approximate location where the person went overboard and to pass over that area again so you can begin an efficient search. The Williamson turn does this by executing a 180-degree turn toward the side of the person overboard and then continuing on a reciprocal course that crosses the original track, bringing the vessel back through the MOB’s location. This creates a broad, systematic search pattern and a predictable track, which helps you spot the person more quickly and reduces the chance of missing them. Other turns may not bring you back through the MOB area as efficiently, making them less effective when visibility is poor.
