What is the most important when selecting a PFD for a passenger?

When selecting a personal flotation device (PFD) for a passenger, the size of the passenger is the most crucial factor. A PFD must fit properly to be effective in keeping someone safe in the water. If a PFD is too large, it may not provide the necessary buoyancy and support if the wearer falls overboard, potentially leading to dangerous situations. Conversely, if a PFD is too small, it might not have the capacity to float the individual or could cause discomfort or restrict movement.

Choosing a PFD that is appropriately sized ensures that the passenger will be able to remain afloat comfortably and securely, which is essential for their safety while boating. Other factors, such as the style, color, or manufacturer, do have their importance, but they pale in significance compared to the correct sizing of the PFD. Proper fit enables the device to function as intended, making it a top priority in ensuring the safety and well-being of all passengers on board.
