Boating accident statistics compiled by the U.S. Coast Guard indicate that 90 percent of people who drown in a boating or water accident would be alive today if they had been wearing a life jacket at the time of the accident.
Who must wear a personal flotation device (PFD) or life jacket?
What type of PFD do I need to carry on my boat in Michigan?
(Off-Shore Life Jacket) (22 lbs. Buoyancy) Best for open, rough or remote water where rescue may be slow in coming.
Advantages: Turns most unconscious wearers face-up in water. Highly visible color. Floats the person the best.
Sizes: Two sizes to fit most children and adults.
(Near-Shore Buoyant Vest) (15.5 lbs. Buoyancy) Good for calm, inland water or where there is good chance of fast rescue.
Advantages: Turns some unconscious wearers face-up in water. Less bulky, more comfortable than Type I PFD. Inexpensive.
Disadvantages: Not for long hours in the water. Will not turn some unconscious wearers face-up in water.
Sizes: Infant, Child Small, Child Medium, Adult.
(Flotation Aid) (15.5 lbs. Buoyancy) Good for calm, inland water or where there is a good chance of fast rescue.
Advantages: Generally the most comfortable type for continuous wear. Freedom of movement for most active water sports. Available in many styles. Freedom of movement for water-skiing, small boat, sailing, fishing, etc.
Disadvantages: Wearer may have to tilt head back to avoid going facedown. In rough water, a wearer's face may often be covered by waves. Not for extended survival in rough water.
(Throwable Device) For calm, inland water with heavy boat traffic, where help is always nearby.
Advantages: Can be thrown to someone. Good back-up wearable PFDs. Some can be used as a seat cushion.
Kinds: Cushions, Rings and Horseshoe buoys.
Disadvantages: Not for unconscious persons. Nor for non-swimmers or children. Not for many hours in rough water.
