A lifeboat is a boat carried on board a ship and designed to allow passengers to escape, or a boat kept on land or in a harbour to rescue people in trouble at sea. Lifeboats are also kept at offshore platforms. As such, it is an elaborate version of a life raft. Lifeboats were historically rigid structures built with highly buoyant materials. More recently however, life rafts are inflatable, equipped with auto-inflation carbon dioxide canisters or mechanical pumps, and split into partitions, so that they are much less subject to the adverse effects of exposure to sea water and sunlight. A quick release and pressure release mechanism is fitted so that the canister or pump automatically inflates the lifeboat, and the lifeboat breaks free of the sinking vessel.
