Man overboard drills play a really important role in Emergency Response Training on board any vessel.

Whether I’m responsible for a yacht, a large commercial ship, or a small workboat, knowing exactly what steps to take when someone goes overboard can mean the difference between a close call and a tragedy. Getting familiar with the best man overboard training not only helps keep everyone safe, but it also gives a boost of confidence for the whole crew. Here, I’m going to break down how to prepare for a man overboard drill, what to expect, and some effective man overboard rescue techniques that anyone working at sea should know. These skills aren’t just for the captain or senior crew – everyone onboard has a part to play in saving a life.

Why Man Overboard Drills Matter

Man overboard (MOB) emergencies are one of the most urgent situations that can happen at sea. If someone falls off the vessel, quick reaction and clear roles are super important. Every second counts. Without practice, panic can slow down a response, create confusion, or lead to mistakes in rescue techniques. That’s why regular Emergency Response Training—including well-planned man overboard drills—builds muscle memory and helps the crew work together smoothly. According to the International Maritime Organization (IMO) and real-world maritime incident reports, most successful recoveries happen when the crew is prepared, organized, and practiced. I always make MOB drills a top training priority, and encourage others to do the same, since even a few minutes’ hesitation can have serious consequences.

Understanding the Goals of Man Overboard Drills

The basic goal of any man overboard drill is to rehearse a fast, safe recovery of someone who has fallen overboard. During the drill, I want to make sure everyone on board knows their specific role, can communicate clearly, and understands the steps for rescuing a person from the water.

• Identify the emergency: How to spot someone overboard and raise the alarm.
• Initiate the rescue: Who throws life rings, who keeps eyes on the person, and who maneuvers the vessel.
• Recovery process: How to bring the person back on board, safely and fast.
• Medical response: What to do once the person is back on board and needs help.

The best man overboard training follows a structured approach that helps the team practice these points until it becomes second nature. But it’s more than following a script; being able to adapt to unexpected events can be just as vital as knowing the textbook steps.

How to Prepare for a Man Overboard Drill

Preparation is more than just gathering everyone on deck. Each time I plan a MOB drill, I make sure to set up the practical details first so the exercise feels as real as possible. Here’s how I prepare for a man overboard drill every time:

• Notify the crew ahead of time. I let the team know about upcoming drills so everyone is mentally ready, but I sometimes run surprise drills too, to check our real response in unexpected situations.
• Assign clear roles. Everyone should know their responsibility – from spotting overboard to handling medical gear after recovery.
• Prep all equipment. Life rings, MOB poles, rescue slings, and heaving lines are set out and checked for condition. On larger ships, the MOB boat or rescue boat is also checked and fueled.
• Review safety procedures. We do a quick refresher on standard man overboard rescue techniques, including signaling, maneuvering, and using safety gear, to ensure no detail is overlooked.

I always find that a strong setup ensures the drill goes smoothly and that training time is used well. Prepping also means testing communication devices such as talk-back systems and portables to guarantee every voice is heard when every second matters.

Key Elements: The Man Overboard Drill Checklist

A clear checklist keeps me organized. Whether I’m running a scheduled drill or a surprise one, I go through this basic man overboard drill checklist:

• Test the MOB alarm and check radios for clear communication.
• Ensure the bridge and deck crew are ready and alert.
• Inspect and position life rings, lights, and buoys for easy access.
• Review how to properly use the vessel’s rescue slings, ladders, or davits.
• If using a dummy or training aid, set it up and agree on the overboard signal.

For a downloadable and printable version of a typical MOB drill checklist, I often use examples provided by maritime authorities and pair them with vessel-specific requirements. You can also check out International Maritime Organization (IMO) guidelines for reference. Over time, experience will help you tweak the checklist so it fits your own vessel and crew’s unique needs.

An Overview of How to Conduct Man Overboard Drills

Running an effective man overboard drill takes a step-by-step process. I try to mirror possible real-world scenarios as closely as possible, while still keeping everyone safe during training. Here’s how I usually conduct a man overboard drill:

1. I announce “Man Overboard” and signal with the MOB alarm.
2. The spotter points continuously at the person or dummy in the water to maintain visual contact.
3. Another crew member throws a buoyant aid toward the person in the water and activates the MOB marker (if available).
4. I or another qualified person take control at the helm and steer with a Williamson turn, Anderson turn, or Scharnow turn. The maneuver depends on the vessel, and practicing different approaches helps everyone feel prepared for anything.
5. The rescue boat team (if available) prepares and launches the MOB boat or rescue gear.
6. Crew coordinate over the radio, updating everyone about position, actions, and the progress of the recovery.
7. The team retrieves the dummy (or person) using lifebuoys, ladders, or slings, following real-life recovery steps.
8. We simulate post-rescue medical care by moving the person to a safe area and doing a mock assessment for hypothermia or injury.

Drills aren’t complete without a wrap-up discussion. After the action, I talk things over with the team, asking everyone what felt clear, what caused delays, and how we can tighten up the process next time. Honest feedback lets us fine-tune techniques and communication both.

The Most Common Man Overboard Rescue Techniques

There’s more than one way to recover someone who has fallen overboard. The method I choose depends on the type of vessel, sea conditions, and how many people are on board. Here are the core techniques I practice with my crew during every Emergency Response Training:

• Throwing a Life Ring: The most immediate action. I instruct someone to throw a life ring or buoy with a line as soon as anyone shouts “Man overboard!” This keeps the person afloat and marks their position.
• Ship Maneuvering: Turning the vessel with the right technique is really important for lining up an approach without creating more danger. The three recognized turns are the Williamson turn, Anderson turn, and Scharnow turn. Each one has a specific time and place, so I always review which fits our vessel before each drill.
• MOB Boats: On large vessels, launching a designated rescue boat is often the fastest way to recover someone. I make sure the crew can launch and retrieve the MOB boat smoothly and safely. In smaller boats, quick maneuvering alongside may be more practical.
• Recovery Devices: Using a rescue sling, Jacobs ladder, or specially designed lifting devices helps minimize risk of injury during recovery. We review how each device works, and I ask team members to practice securing and lifting a dummy with every type we have onboard.

I remind everyone that whatever technique we use, good teamwork and constant communication are what save lives. It’s also essential to adapt on the fly. Sometimes, a strong current, cold weather, or equipment snag can change the game – being flexible and thinking clearly in the moment is invaluable.

Essential Gear for Man Overboard Drills

Having the right equipment is absolutely necessary for both effective training and real-life emergencies. For man overboard drills, I always double-check the following gear:

• Life rings (with lines attached)
• MOB marker buoys and DAN buoys
• Throw bags or floating lines
• Rescue slings or MOB recovery cradles
• Rescue ladders and portable steps for retrieval from the water
• Signal flags or air horns for visual and audible alerts
• MOB alarms and automatic tracking systems (for larger vessels)
• First aid kits, blankets, and emergency medical equipment

I personally check each piece of gear for good working order before a drill. If anything’s worn or damaged, I’ll replace it right away to avoid future problems. Up-to-date equipment can save a life, so regular inspections are just as important as the drill itself.

What to Watch Out For: Challenges During Man Overboard Drills

There are common issues that can come up, even in a practice scenario. I always keep these in mind:

• Weather and Visibility: Bad weather, high winds, or big waves make MOB drills more realistic, but they can also increase the risk and slow everything down. I do a quick risk assessment before starting. Don’t forget, night-time or fog drills prepare the crew for the toughest possible situations.
• Fatigue and Distraction: Drills run during long shifts or after hours can make the team slow to react or miss steps. I schedule drills when the crew is alert and focused for everyone’s safety.
• Panic and Communication Breakdowns: Even in training, stress can cause confusion and mistakes. I run through the drill step by step and keep communication clear and simple. Practice helps calm nerves and gives the team a blueprint to follow if real trouble happens.

Working through these details in practice helps us deal with them better in real emergencies. Even small glitches in a drill can be learning opportunities, helping prevent much bigger mistakes down the line.

Advanced Tips for Getting the Most Out of Man Overboard Drills

Once the basics are in place, I look for ways to get even more value from our drills. Here are some tricks I’ve picked up over time:

• Run drills at different times of day, including at night, to prepare for reduced visibility and fatigue. Introducing unexpected situations makes each drill unique.
• Switch up roles so everyone gets a chance to practice each responsibility. It’s important everyone knows each station, not just their main one—smaller crews especially need this flexibility.
• Use training dummies that are weighted and float realistically to make the rescue feel authentic. The more lifelike the dummy, the more confident the crew will be in real emergencies.
• Integrate medical response training by simulating cold water shock, unconsciousness, or injury as part of the drill. Add CPR and recovery position practice for complete realism.
• Ask for honest feedback from everyone after the drill, then use it to improve our checklist and procedure. Encourage quiet crew members to share ideas—they often have great observations.

This variety not only helps the crew master the basics but also builds adaptability for real emergencies. Changing up location, speed, or order of actions keeps everyone sharp, so when the unexpected occurs, we’re not starting from scratch.

Frequently Asked Questions About Man Overboard Drills

How often should I conduct man overboard drills?
Most maritime authorities recommend practicing MOB drills at least once a month, but I find that more frequent short drills, combined with formal full drills, keep the team sharp. For commercial ships, it’s a legal requirement to conduct MOB drills at minimum prescribed intervals; always check your flag state’s regulations and make sure you’re in compliance. If in doubt, more practice is better than too little.

What’s the best way to train a new crew member on man overboard rescue techniques?
I start with a walk-through on deck, explaining each piece of rescue equipment, signaling systems, and basic turns. Afterward, I invite the new crew member to observe a drill so they can see the whole process in action. Gradually, I let them take on more responsibility during the next drills, always with support nearby for questions. Confidence grows with experience, especially when it’s reinforced by hands-on training.

Can MOB drills be done while underway?
Yes, and in fact, practicing under operating conditions adds the most value. I make sure everyone is briefed in advance and there are enough people to safely operate the vessel. Safety always comes first, and practicing with the vessel moving gets everyone used to handling realistic situations where the boat is not anchored or docked.

What reporting or documentation do I need after a drill?
After each man overboard drill, I record the names of those involved, time and location, key actions taken, and notes about what went well or needs work. Many vessels keep a training log or safety management system for these records. Documentation helps track progress over time and provides proof of training for inspections and audits.

Man Overboard Drill Best Practices for Different Vessel Types

Every vessel is a little different, and I adjust my drills to fit. Here are a few things I keep in mind for different boats:

• Sailboats: I prepare for MOB drills by practicing with the boat both under sail and under engine, using harnesses and jacklines for safety. It’s crucial everyone knows how to quickly tackle sails to slow the vessel and change direction if needed.
• Commercial Ships: MOB drills involve more people and specialized gear. I verify crane or davit operation for life rafts and MOB boats. The complexity means detailed planning and plenty of backups are required.
• Small Workboats: With fewer people, I pay close attention to working lines and approach angles for lifting someone from the water safely. Fast action can be lifesaving in these scenarios.

Matching the drill to the actual vessel makes it much more relevant for the crew and gives a boost to real-world performance. No two boats handle exactly the same, so even experienced crew benefit from tailored training.

How Regular Drills Build Safety Culture

An ongoing routine of man overboard drills helps create a safety-focused atmosphere on board. When I consistently lead MOB training and encourage crew to share their suggestions, I notice stronger teamwork and more attention to detail. Regular Emergency Response Training also shows inspectors and authorities that we take safety seriously, which can affect insurance, reputation, and even legal compliance. It really pays off on a day-to-day basis, not just when something goes wrong. Crew members learn to trust each other and speak up if something seems off during operations, reflecting a culture where safety always comes first.

Wrapping Up: Why Consistency and Practice Are Key

Practicing man overboard drills does more than just meet legal requirements; it helps make everyone on board feel more confident and safe. I can see the difference in reaction time, teamwork, and problem-solving every time we run a drill. The crew learns what to expect, how to communicate, and how to work together quickly in an emergency.

If you’re looking to raise the level of emergency safety on your vessel, consistent, realistic man overboard drills should always be at the top of your list. The best teams treat drills as real-life practice, not just a tick-box exercise. Prioritizing these exercises is a proven way to protect lives at sea.
