Which type of PFD is designed to turn most unconscious people face up in the water?

The Type I Personal Flotation Device (PFD) is specifically designed to provide maximum buoyancy and is well-suited for rough or remote waters. One of its primary features is its ability to turn most unconscious wearers face up in the water, a crucial safety aspect for individuals who may not be able to help themselves in an emergency situation. This type of PFD's high buoyancy is achieved through its construction and the materials used, which typically include foam that provides significant lift.

Type I PFDs are ideal for offshore use or in situations where rescue may take longer because they offer the best safety margin for users who may be incapacitated. This makes them an effective option for conditions where the risk of falling overboard or becoming incapacitated is high. In comparison, other types of PFDs are designed with different uses in mind, focusing on comfort and maneuverability rather than providing the necessary buoyancy and turning capability when someone is unconscious.
