All vessels must be equipped with USCG–approved personal flotation devices (PFDs), sometimes called life jackets. The quantity and type depend on the length of your vessel and the number of people on board and/or being towed. Each PFD must be in good condition, be the proper size for the intended wearer, and very importantly, be readily accessible! Readily accessible means you must be able to put the PFD on in a reasonable amount of time in an emergency (vessel sinking, on fire, etc.). PFDs should not be stowed in plastic bags or in locked or closed compartments, and they should not have other gear stowed on top of them.
Vessel operators should ask everyone on their vessel to wear a PFD whenever on the water. PFDs can save lives, but only if they are worn!
