Man Overboard Recovery: Equipment and Techniques

Essential Equipment for Man Overboard

Having the right gear readily accessible is the first line of defense. Key items include:

• Personal Flotation Device (PFD) with harness and tether: The person overboard should already be wearing a PFD, preferably an inflatable type with automatic activation and a whistle. A harness and tether can prevent the person from drifting away from the boat, especially on a heeling sailboat[1].
• Throwable flotation devices: Devices such as a Lifesling, heaving line, or ring buoy with a drogue can be thrown to the victim to provide buoyancy and a means to pull them back to the boat. The Lifesling, in particular, is designed for easy throwing and retrieval[2].
• MOB retrieval aids: A dedicated MOB ladder, net, or shallow cockpit well can help lift the person aboard. Some boats install a dedicated MOB pulpit or a removable transom gate.
• GPS/Chartplotter MOB function: Most modern chartplotters have a dedicated MOB button that marks the exact location and can guide you back with a course-to-steer line. Activate it immediately[3].
• VHF radio: Use it to broadcast a Mayday and coordinate with nearby vessels or shore rescue if needed.

All this gear should be readily accessible, not stowed below. Conduct regular inspections to ensure everything is in good condition and you know how to use it[4].

⚓ Expert Tip: Before any offshore passage, do a full gear check: batteries charged, expiration dates current, spare parts accessible.

Immediate Actions: The 3 Ps – Protect, Position, Preserve

When someone goes overboard, your reaction must be swift and decisive:

• Protect: Shout “Man Overboard!” and alert the entire crew. Immediately throw a flotation device to the victim. If the engine is running, put it in neutral to avoid propeller injury, but keep the boat in gear enough to maintain steerageway if needed. Some captains keep the engine running at idle to maintain steerage, using a crew member as a dedicated propeller spotter[5].
• Position: Assign a crew member to keep the victim in sight at all times. Use GPS MOB button. Turn the boat around to return to the victim. There are two primary turn methods: the quick‑turn ( Williamson turn for powerboats, or a tack‑and‑gybe for sailboats) and the figure‑8 turn for larger vessels. The choice depends on boat type and crew skill[1].
• Preserve: Keep the victim warm and calm. If the victim is in the water for an extended period, hypothermia is a major risk. Have a heated survival suit ready if conditions are cold.

Recovery Techniques for Sailboats

Sailboats present unique challenges due to masts, rigging, and heeling. The recovery must be adapted to the point of sail:

Recovery on a Close Reach (Wind on the Side)

If the boat is on a close reach when MOB occurs, the usual approach is to turn the boat into the wind (head to wind) and then bear away onto the opposite tack, bringing the victim on the leeward side. This keeps the rigging and boom away from the person in the water[2]. The steps:

1. Shout MOB and throw flotation.
2. Release the mainsail from the winch (if possible) to allow free movement.
3. Turn the boat onto the opposite tack using a series of tacks or a gybe depending on wind direction.
4. Approach the victim on the leeward side, with sails luffing to reduce speed.
5. Heave the line or use a boat hook to pull the victim alongside.
6. Use the winch or a block-and-tackle to hoist the person aboard, preferably at the lowest point of the deck (like the companionway or a stern gate).

Recovery on a Run (Wind from Behind)

A person overboard while running may end up in the boat’s “vacuum” behind the mainsail, making recovery harder. The recommended technique is to bear away sharply, then turn the boat upwind to approach on a close reach, again bringing the victim on the leeward side. Avoid gybing with crew on deck unless absolutely necessary due to the danger of an uncontrolled boom swing[3].

In all cases, keep the propeller away from the victim. If using an engine to maneuver, assign a spotter to watch for the person in the water.

Recovery Techniques for Powerboats

Powerboats can maneuver more quickly and have less rigging to worry about. The standard recovery is a reverse turn (also called a Williamson turn) that brings the boat back on its own wake to the victim’s location. Steps:

1. Mark MOB on GPS.
2. Put the helm over hard in the direction of the initial turn (usually away from the victim to avoid propellers).
3. Once the boat has turned about 240 degrees, straighten the helm and maintain course until the wake is abeam.
4. Then turn the boat to approach the victim on the leeward side (relative to wind).
5. Slow to a crawl and use a ladder or assist the victim to climb aboard[4].

Powerboats with bow and stern thrusters can use them to fine‑tune the approach without using propeller thrust too close to the person.

Drills and Training

Practice makes perfect. The US Coast Guard and sailing organizations recommend conducting MOB drills at least quarterly, and ideally monthly when learning[5]. A typical drill:

• Have a crew member throw a buoy or weighted dummy overboard (or use a dedicated MOB training device).
• Call “Man Overboard!” and activate the GPS MOB function.
• Execute the recovery maneuver appropriate to the point of sail.
• Practice retrieving the object and bringing it aboard using the intended method (ladder, net, hoist).
• Time the drill; aim to have the victim recovered within 2–3 minutes in good conditions.

Record the results and identify improvements. Crew roles should be assigned in advance: spotter, thrower, helmsman, and retrieval crew.

Medical Considerations

Once the victim is aboard, assess for injuries and hypothermia. Even in warm water, shock and hypothermia can set in quickly. Remove wet clothing, provide dry thermal protection, and give warm, sweet fluids if the person is conscious and not injured. Seek medical attention as soon as possible, especially if there was a head injury or prolonged immersion[1].

Conclusion

A successful man overboard recovery depends on preparation, equipment, practice, and calm execution. By knowing your gear, training your crew, and mastering the maneuvers, you dramatically increase the chances of a positive outcome. Make MOB drills a regular part of your sailing routine.
