Which is a characteristic of a Type III Personal Flotation Device (PFD)?

A Type III Personal Flotation Device (PFD) is primarily designed to provide buoyancy and keep a wearer afloat in calm waters, but it does not provide the same level of safety for unconscious individuals as some other types do. One key characteristic of Type III PFDs is that they are not meant to turn most unconscious wearers face-up in the water. This is an important consideration for boaters, as it emphasizes the limitations of Type III PFDs in emergency situations where a person may become incapacitated.

The other choices refer to attributes more applicable to other types of PFDs, such as those designed for rough waters or those that are solely throwable. Understanding the purpose and limitations of each type of PFD helps boaters make informed decisions about safety equipment that best suits their specific boating environment and activities.
