What is the primary purpose of wearing a PFD at all times on open water?

• A. To provide buoyancy and keep your airway above water in a fall-overboard situation.
• B. To prevent rain exposure
• C. To improve speed
• D. To comply with regulations

Answer: (A)

The main idea is that a PFD provides buoyancy to keep your airway above water. On open water you can suddenly fall overboard, be knocked unconscious, or become exhausted and struggle to swim. The PFD supplies enough floating support so you stay afloat without needing to use energy, keeping your head and airway out of the water and making it easier for you to breathe and for rescuers to find you. While regulations may require wearing one, that regulatory aspect is separate from the device’s primary safety function. The other options—protecting from rain, increasing speed—aren’t the core reason a PFD is worn; flotation and keeping you safe in the water is.
