What is the main function of a personal flotation device (PFD)?

The primary function of a personal flotation device (PFD) is to keep a person buoyant and prevent drowning. PFDs are designed to help individuals stay afloat in the water and significantly increase their chances of survival if they fall overboard or encounter an emergency situation in which they end up in the water. They are essential safety equipment that provides the necessary support to keep a person's head above water, thereby allowing them to breathe and potentially signal for help.

While comfort and storage are important aspects of boating gear, they do not directly relate to the primary life-saving function of a PFD. The focus of a PFD is strictly on buoyancy and ensuring the safety of a person in aquatic environments.
