HARRISBURG — The state Fish and Boat Commission reminds boaters that from now until April 30, 2014, they are required to wear a life jacket while under way or at anchor on boats less than 16 feet in length or on any canoe or kayak.

The requirement applies to all state waters.

A disproportionate number of the fatalities occur in November through April. During these cold weather months, boaters are especially at risk due to the water temperature and the risk of sudden cold water immersion.

When a person is unexpectedly plunged into cold water below 70 degrees, the body’s first response is usually an involuntary gasp.

Without a life jacket, a victim may inhale while under water and drown without coming back to the surface. If an individual does make it back to the surface, his ability to swim is usually restricted because of a shortness of breath or hyperventilation.
