Survivors of cold water accidents often describe having their breath 'knocked out' of them upon their first impact with the water. Disorientation may also occur after cold water immersion. People have been observed thrashing helplessly in the water for 30 seconds or more until they were able to get their bearings. In addition, immersion in cold water can quickly numb the extremities to the point of uselessness. Cold hands may be unable to fasten the straps of a life jacket, grasp a thrown rescue line, or hold onto a boat.
Proper preparation is important when boating on cold water.
When taking the boat out early in the season, and especially when hunting and fishing, form a group and take several boats along. Dress properly for the cold. Several layers of light clothing offer better protection than a single heavy layer. Next to a divers wet suit, wool clothing offers the best protection. Always wear your life jacket when on the water.
