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

The most important factor when selecting a personal flotation device (PFD) for a passenger is the passenger's size. A PFD must fit properly in order to be effective in providing buoyancy and safety in the water. If a PFD is too large, it may not hold the wearer above the water, and they could risk slipping out of it. Conversely, if it is too small, it may be uncomfortable and could be inadequate in an emergency situation.

Proper sizing ensures that the PFD provides the intended level of safety and protection. It allows for adequate movement while securing the individual in place, which is crucial should they end up in the water. Manufacturers typically provide guidelines for sizing based on weight and chest measurement, enabling boaters to select appropriately.

While the color of a PFD, brand reputation, and price may have their own importance—such as visibility for rescue situations or personal preference—none of these factors outweighs the necessity of ensuring that the PFD fits the wearer correctly. Safety should always be the primary consideration when choosing any safety equipment for boating.
