Overboard means over the side of the boat and into the water. It applies to anything from a winch handle to a person, but it is the phrase ‘man overboard’, shortened to MOB and increasingly rendered as crew overboard or person overboard, that every sailor learns first and hopes never to hear. For the beginner the essential lesson is that a person in the water is a boat-handling problem before it is a swimming problem: the boat must be stopped, turned and brought back alongside under control. The experienced skipper adds a sobering detail: in cold water the first minute is dominated by cold-shock and gasping, not by drowning or hypothermia, and a casualty without a lifejacket may be lost in that minute regardless of how quickly the boat comes back.
Prevention Comes First
The best recovery is the one you never have to make. Lifelines, jackstays and tethers exist so that crew moving around the deck at night or in heavy weather cannot leave the boat. The rule on a well-run yacht is simple: clip on before leaving the cockpit whenever the skipper says so, and the skipper says so at night, when reefed, when anyone is on the foredeck in a seaway and whenever a crew member is alone on deck. Lifejackets are worn, not stowed, in the same conditions.
The Recovery Sequence
The instant someone goes over, the crew’s actions should be automatic, which is why the drill must be practised. Shout ‘man overboard’ so the whole boat knows. Throw flotation: horseshoe, danbuoy, a cushion, anything that floats and marks the spot. Detail one person to point at the casualty and do nothing else; a head in a seaway vanishes in seconds. Press the MOB button on the plotter so there is a position to return to. Then manoeuvre.
The quick-stop turns the boat immediately head to wind and tacks without releasing the headsail, so she heaves-to with the jib aback within a boat length or two of the casualty, then circles under control. The reach-tack-reach, or figure-of-eight, bears away onto a beam reach for a few lengths, tacks, and returns on a close reach with the sails eased to control speed. Under engine the boat turns tightly, but the propeller becomes lethal near a person in the water and must be in neutral for the final approach. Whichever method you use, the final approach is the same: slowly, on a close reach where speed can be controlled with the sheets, stopping with the casualty at the shrouds where the freeboard is lowest.
Getting Them Back Aboard
Lifting a cold, heavy, possibly unconscious person up a metre of freeboard is often the hardest part. A Lifesling or similar rescue collar lets you make contact by circling and towing the line to the casualty, then hoist them with a halyard led to a winch. Once aboard, treat for hypothermia and shock: horizontal, out of the wind, wet clothes off, dry insulation on, warm slowly, and keep watching them for hours afterwards.
Cruising and Racing Perspectives
The cruising couple faces the hardest version of this problem: one person left aboard, often the less experienced, with a boat under full sail and autopilot. Short-handed cruisers should practise single-handed recovery, rig the boat so sails can be depowered from the cockpit and treat the tether as non-negotiable.
Racing crews are more numerous and more practised, and offshore racing regulations require regular crew-overboard drills, specified safety gear and, in many events, personal locator beacons for every crew member. The Racing Rules of Sailing make the duty plain: a boat must give all possible help to any person or vessel in danger, and a boat that abandons a race to do so is entitled to redress. No trophy is worth a crew member.
Frequently Asked Questions about Overboard Recovery
Should I approach the person from windward or leeward?
The usual teaching is to make the final approach on a close reach and stop with the casualty on the leeward side, slightly forward of the beam, so the boat gives them a lee and drifts gently down onto them. In a big sea some skippers prefer to stop to leeward so the boat cannot be dropped onto the casualty by a wave. Practise both and know your boat.
Should I start the engine?
Starting it is usually right, because it gives options if the sails are a handful. Using it near the casualty is another matter: the propeller must be in neutral for the final approach and trailing lines kept clear of it.
How long do I have in cold water?
Less than you think. Cold-shock lasts a minute or two, useful swimming ability may be gone in ten to fifteen minutes in water around 10 °C, and unconsciousness from hypothermia may follow within an hour. A lifejacket buys time through every stage.
Overboard is the one word at sea that turns a good day into a crisis in a heartbeat. See also lifeline, jackstay, tether, heave-to and lifejacket. Clip on, wear the lifejacket, practise the drill until it is boring, and you will very likely never need it. If you ever do, the practice is what will bring your crew home.
