Exposure to the elements seems the most common reason I've found in my research of what causes personal flotation devices to wear out.
Type IV Personal Flotation Devices (PFDs) are designed as throwable devices, such as cushions or rings, rather than wearable life jackets. They are meant to be thrown to someone in distress rather than worn continuously. These devices typically provide buoyancy to assist individuals who are in the water but may not be suitable for prolonged use or for those who cannot swim. Type IV PFDs are often used in conjunction with other flotation devices for added safety.
In case of an emergency passengers have access to flotation devices and oxygen masks.
Type I, II, or III PFD
Children must wear personal flotation devices at age 12 and younger.
If an individual is too far from their capsized boat to use it for flotation, they should try to stay calm and conserve energy. They can use any available flotation devices, such as life jackets or other objects in the water, to help keep them afloat. If no flotation devices are available, the person should float on their back to minimize energy expenditure and keep their head above water while signaling for help if possible. It's crucial to stay as visible as possible to rescuers.
