In my experience, man overboard is the most likely emergency in recreational sailing, and one of the deadliest. Not because procedures don't exist — they do, and they're well defined — but because almost nobody practises them before needing them. In the moment, improvisation kills.
Why man overboard is so dangerous
Three factors make this emergency especially critical in Chile:
Water temperature. In the southern channels and Patagonia, the sea sits between 6°C and 10°C year-round. At that temperature, a person without an immersion suit loses the ability to swim in a coordinated way within 10-20 minutes and can die of hypothermia in 30-90 minutes. There's no time for slow or hesitant manoeuvres.
The difficulty of night rescue. Global statistics are consistent: half of man-overboard incidents happen at night or in reduced visibility. Finding a person in the water at night, even with a light, is extraordinarily difficult without an active locating system.
The difficulty of getting them back aboard. Hauling an unconscious or hypothermic person onto a keelboat with more than a metre of freeboard, in a seaway, requires specific equipment and prior practice. Without a boarding ladder or a hoisting system, it can be impossible.
The first 30 seconds
The first 30 seconds after the incident are the most critical. The actions need to be automatic:
- Shout "Man overboard!" — alert the whole crew immediately
- Throw the lifebuoy — no need to aim, as close as possible without hitting them
- Designate a spotter — one person whose only job is to never lose sight of the person in the water. This person points with an extended arm and never lowers it
- Press MOB on the GPS/plotter — log the position at the moment of the incident
- Reduce speed and manoeuvre
The most common mistake: not designating a dedicated spotter. Everyone watches while the manoeuvre happens, and between the boat's motion and the swell, the person is lost from sight within seconds. Recovering someone who's been lost from sight in dark or rough water is nearly impossible without electronic locating.
The under-power manoeuvre: the Quick Return
With the engine running, the fastest manoeuvre is the Quick Return, or Q manoeuvre:
- As the person falls, motor forward 6-8 boat lengths to move the propeller away from them
- Turn toward the side they fell from (this moves the stern and propeller away)
- Complete a full arc until you're on a reciprocal heading
- Approach the person with the wind on your port bow (engine to port), which will naturally slow the boat once you cut the engine
- Cut the engine 5-10 metres out to eliminate propeller risk
"Practise the man-overboard manoeuvre in controlled conditions, with someone in the water in a wetsuit, before you ever need it for real. That's the only way it becomes a reflex."
Minimum equipment per vessel
The difference between a successful recovery and a tragedy is often the equipment available and how accessible it is:
- Lifebuoy with automatic light: the light activates on contact with water. Mandatory for night navigation
- Drogue or "horse's tail": a short line attached to the buoy that increases drag in the water and stops it drifting away with the wind
- MOB marker / PIW marker: a bright signal buoy with a flag, pole and, in some models, a strobe light, thrown alongside the lifebuoy to mark the point of falling
- Boarding ladder: with rungs that reach the water and are accessible from the side of the boat, not only the stern
- Recovery halyard or tackle: to hoist an unconscious or incapacitated person
- A PLB per crew member: the ultimate insurance for locating the person in the water
Water temperature and rescue time in Chile:
- Santiago / Valparaíso (summer): 14–18°C — survival 1-6 hours
- Chiloé / Puerto Montt: 10–13°C — survival 45 min to 3 hours
- Southern channels / Patagonia: 6–10°C — survival 30–90 minutes
- Cape Horn: 4–7°C — survival 15–45 minutes
Personal equipment: harness and lifeline
The best man-overboard strategy is not falling in the water at all. For night navigation, foul weather, or working on deck in difficult conditions, a harness clipped to the boat's jackstay is the first line of defence. In the southern channels with williwaw winds, this is a rule that isn't up for negotiation.
