What is the basic MOB (man overboard) response sequence?

• A. Shout, throw a flotation aid, keep sight of the person, alert others, and execute recovery per local procedure.
• B. Immediately swim to the person
• C. Turn off engine and wait for someone else to act
• D. Get back to shore and call base

Answer: (A)

When a person goes overboard, the first priority is to establish a quick, organized response that keeps the casualty buoyant, visible, and within reach while the crew coordinates the rescue. The best sequence starts with shouting to draw the person’s attention and confirm you see them, which also helps keep them calm. Immediately throwing a flotation aid gives instant buoyancy support and creates a visual target so others can spot the casualty more easily. Keeping the person in sight at all times prevents losing track in waves or dark conditions, which is crucial for a successful recovery. Alerting others on board mobilizes the team and resources, ensuring the rescue is supported with additional help, equipment, and communications. Finally, executing the recovery per local procedure ensures the maneuver is done safely and consistently with the vessel’s trained method, using the proper equipment and steps for bringing the person aboard or bringing them to a safe position without putting rescuers at unnecessary risk.

Swimming to the person, turning off the engine and waiting, or returning to shore to call for help all delay action or remove critical control from the scene, increasing risk to the missing person and the crew. Following a defined MOB procedure on site is what maximizes safety and effectiveness.
