Why should you refrain from using a personal flotation device as a cushion or fender?

Using a personal flotation device (PFD) as a cushion or fender can compromise its integrity and safety features. PFDs are designed to provide buoyancy and support in emergencies, and using them for non-intended purposes may damage the material or buoyancy components. This could render the device ineffective in a critical situation, putting you and others at risk. It's essential to use equipment as intended to ensure safety on the water.
