Young Black Haired Girl On The Lake With The Ring Buoy

A lifebuoy, ring buoy, lifering, lifesaver or lifebelt, also known as a "kisby ring" or "perry buoy", is a life saving buoy designed to be thrown to a person in the water, to provide buoyancy, to prevent drowning. Some modern lifebuoys are fitted with a seawater-activated light, or lights, to aid rescue at night.
The lifebuoy usually is ring-shaped or horseshoe-shaped and has a connecting line allowing the casualty to be pulled to the rescuer. They are carried by ships and are also located beside bodies of water that have the depth or potential to drown someone. They are often subjected to vandalism, which can lead to heavy fines of up to £5000 and/or imprisonment in the United Kingdom of Great Britain and Northern Ireland, as a lack of this essential device has been, in the past, the cause of deaths.
The "kisby ring", or sometimes "Kisbie ring", is thought to be named after Thomas Kisbee (b: 1792, d: 1877) who was a British naval officer.
