Person overboard and cold water: key rules to remember

Our summary of what the official handbook says on this topic, in our own words. Read it before or after the practice questions above, then check the original chapter. Read the official chapter ↗

Falling overboard

  • Falling overboard is one of the main ways people die in recreational boating in Canada; wearing a lifejacket cuts the risk.
  • Causes: waves, slippery decks, sudden sharp turns, collisions. A quick-release harness and safety line can help.
  • If someone falls overboard: sound the alarm; slow down and stop if possible; throw something that floats (also marks the spot); assign one person to watch the person constantly; position the boat carefully; recover with a floating heavy line or a lifebuoy on a line; bring the person aboard on the windward side.
  • During recovery turns: go slow, know where the person is, keep the propeller far away.
  • Anderson (single) turn: fastest; calm water, good visibility. Reduce speed, rudder hard over toward the victim, turn about 250 degrees (about 2/3 of a circle), approach with the victim ahead of the propellers, engine in neutral to recover.
  • Williamson turn: delayed response or poor visibility (night, waves). Rudder hard over toward the victim's side; after 60 degrees off course, hard over to the opposite side; 20 degrees short of the opposite course, rudder midships; come upwind of the person; stop alongside in neutral.

Reboarding and cold water

  • Reboarding device needed if the climb is more than 0.5 m (1'8"); may be a ladder, lifting harness, rope, chain or cable - not part of the motor; a rope used for reboarding can't be used for anything else.
  • About 94% of Canadian boaters who drown were in water under 20°C.
  • 1-10-1 Principle: 1 minute cold shock (sudden gasp, hyperventilation 600-1000% faster than normal) - keep airway clear, stay calm, slow your breathing. Even strong swimmers suffer cold shock.

Cold incapacitation and hypothermia

  • About 10 minutes cold incapacitation: lose meaningful movement of arms, legs, fingers; focus on self-rescue or keep airway out of the water; without a lifejacket you will likely drown. Putting on a lifejacket in the water is very hard.
  • About 1 hour to lose consciousness from hypothermia, even in ice water. Hypothermia = body temperature below 35°C.
  • Signs: shivering, slurred speech, weak irregular pulse, slow shallow breathing, clumsiness, odd behaviour, confusion or sleepiness, stopped breathing, unconsciousness.
  • Prevent: don't overload, avoid falling overboard, wear your lifejacket.
  • In the water: save energy and heat; swim only to join others or reach safety; don't swim to keep warm; climb onto floating objects.
  • H.E.L.P. (heat escape lessening position): arms crossed tight against chest, knees drawn up. Huddle: chests close together, arms around each other's backs, legs intertwined.
  • Spring/fall/winter: light dry layers plus water/windproof outer layer under the lifejacket; consider floater/survival suits, dry suits, wet suits, immersion suits.
