What is the primary purpose of a Personal Flotation Device (PFD)?

The primary purpose of a Personal Flotation Device (PFD) is to keep a person afloat in water. PFDs are designed to assist in buoyancy, ensuring that, in the event of an accident or capsize, individuals remain on the surface of the water. This fundamental function is critical in enhancing safety while boating, as drowning is a significant risk when someone finds themselves in the water unexpectedly.

While comfort, identification, or protection against cold water can be secondary benefits or considerations, they do not represent the main intent behind the design and use of PFDs. The essential characteristic and requirement of PFDs is their flotation capability, which is vital for survival in aquatic environments. By ensuring that individuals can float, PFDs help reduce the risk of drowning and promote safer boating practices.
