Cold Water Survival: The 1-10-1 Principle

Cold Water Survival in Alaska

Prince William Sound’s water temperature averages 46°F year-round. Five out of six recreational boating fatalities are the result of a vessel capsize, swamping, or a fall overboard into Alaska’s cold water.

The 1-10-1 Principle

If you fall into cold water, remember 1-10-1:

• 1 Minute to control your breathing: The initial shock of cold water causes an involuntary gasp reflex and hyperventilation. Do not panic. Focus on keeping your airway clear and getting your breathing under control within the first minute.
• 10 Minutes of meaningful movement: You have approximately 10 minutes of functional movement in your arms and legs before cold water incapacitation sets in. Use this time to self-rescue, re-board your vessel, or activate your emergency beacon. Do not waste time removing clothing.
• 1 Hour of consciousness: Even in cold water, you can remain conscious for up to an hour if you are wearing a life jacket and can keep your airway clear of water.

Prevention & Preparation

• Always wear a properly fitted life jacket when in an open boat or on deck.
• Equip your boat with at least one re-boarding device so you can get out of the water quickly.
• Carry emergency communication and distress signaling devices on your person.
• Attach the engine cut-off device when underway, especially when operating solo.
