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

The primary purpose of a Personal Flotation Device (PFD) is to provide buoyancy and keep the wearer afloat in water. A PFD is designed to help individuals stay on the surface of the water, reducing the risk of drowning. By offering buoyancy, it allows users to conserve energy and stay safer in situations where they may find themselves in the water unexpectedly, such as capsizing or falling overboard.

While a PFD can contribute to safety in various ways, its fundamental function is focused on flotation. This design is crucial in ensuring that anyone who might be immersed in water can remain at the surface until help arrives or they can swim to safety. The buoyant properties of PFDs are essential, especially in emergency situations, making it a vital piece of safety equipment for boaters and water enthusiasts.

Other options, while potentially related to water safety, do not align with the main role of a PFD. Increasing boat speed or acting as a signal is not the primary function of these devices, and while they can offer some thermal protection, it is not their main purpose.
