Which statement best describes the use of markers or radar in MOB search?

• A. Markers are used to ensure a faster hull speed.
• B. Radar should be turned off during MOB search.
• C. Markers or radar help track the MOB search area and coordinate with the crew.
• D. Markers replace the need for shouting.

Answer: (C)

Using markers or radar in a Man Overboard search gives the team a shared reference frame and keeps everyone aligned on where to search and how to move next. Dropped markers or floating buoys mark the last known position or the edges of the search area, so crew members can see at a glance which sectors have been covered and what area remains to be scanned. This visual reference prevents gaps or overlap and helps coordinate movements, timing, and shifts of responsibility.

Radar adds an electronic lookout, especially in low visibility, by showing objects on the water and tracking drift patterns. It helps you confirm the MOB’s location or the general area to search, monitor progress, and communicate a consistent picture to the whole crew. Together, markers and radar support deliberate, organized search patterns and clear teamwork.

The other options don’t fit the situation: hull speed isn’t about locating a person in the water, radar isn’t something to turn off during a MOB search, and markers don’t replace vocal or radio calls—you still need to communicate clearly while using markers or radar to maintain the shared reference.
