What is the purpose of wearing a personal flotation device (PFD) while boating?

Wearing a personal flotation device (PFD) while boating is crucial for safety, as it provides buoyancy and keeps a person afloat in water. In the event of an emergency, such as falling overboard or a boat capsizing, a PFD can significantly increase the chances of survival by preventing drowning and aiding in flotation. The primary function of a PFD is to help individuals stay above water until help arrives or they are able to swim to safety. This emphasizes the importance of having a PFD readily available for all passengers onboard, especially in situations where the water conditions may become hazardous.
