Capsizing and falls overboard into cold water account for a high number of boating fatalities. Boaters’ risk of dying increases with colder water temperatures. Sportsmen who hunt or fish from boats in cold weather are at greater risk of fatalities from capsizing or falling overboard. Water temperature varies by season and location, but the water does not have to be exceptionally cold for someone to experience the effects of cold water immersion. Researchers (Golden and Harvey 1981) identified four distinct stages in which a person immersed in cold water may become incapacitated and die. Boaters who understand the physiology of cold water immersion, understand the behaviors and conditions that cause immersion events (such as reaching overboard and improper loading), are adequately prepared for a cold water immersion event (such as wearing life jackets and carrying communication devices), and understand the decisions that should be made during such an event, have a greater chance of avoiding cold water immersion or surviving if it does occur.
