In contrast, a lifeboat is open, and regulations require a crew member to inspect it periodically and ensure all required equipment is present. [citation needed] Modern lifeboats have a motor; liferafts usually do not. Large lifeboats use a davit or launching system (there might be multiple lifeboats on one), that requires a human to launch.
Davit systems are most often used to lower an emergency lifeboat to the embarkation level to be boarded. The lifeboat davit has falls (now made of wire, historically of manila rope) that are used to lower the lifeboat into the water. [3] Davits can also be used as man-overboard safety devices to retrieve personnel from the water.

The lifeboats power came from twin General Motors GM6V92TA DDEC turbo-charged marine two-stroke diesel engines which could develop 525 brake horsepower (391 kW). These engines could push the lifeboat to a top speed of 18 knots (33 km/h). At full speed there was enough diesel fuel in the tanks for ten hours service. At lower speeds the endurance ...
