Personal Floatation Devices (PFD's) are classified according to their intended use and their ability to perform as a lifesaving device, keeping the head clear of the water. A "type III" buoyancy device is called a Flotation Aid. It supports 15.5 lbs and is sufficient to keep an adult's head clear of the water in calm conditions. They are more comfortable than Type I and Type II but are not capable of keeping an unconscious person face up, and may not work well in rough seas.
