LIFEBOUYS

A lifebuoy is a life-saving buoy designed to be thrown to a person in water, to provide buoyancy and prevent drowning. Some modern lifebuoys are fitted with one or more seawater-activated lights, to aid rescue at night.

A life buoy is any kind of buoyant device for keeping people afloat in an emergency. A lifebuoy should be secured to the rail of the boat if a rail is fitted but ensure that disconnection can occur within seconds should someone enter the water unexpectedly.
