Lifeboats play an important role on ships and in case of an eventuality, they’re the means by which lives can be saved and the crew can travel safely ashore. Each ship, depending on where it is manufactured, is fitted with a different type of lifeboat. Companies have to follow strict regulations regarding the number of lifeboats on board and the upkeep of these is of central importance for a ship to meet and pass safety standards.
Lifeboats can also be kept on shore to rescue people who are in trouble at sea. These small rigid vessels, which can also be referred to as elaborate versions of a life raft, are secured on the ship into davits which allows it to be launched from the side of the ship, saving crucial escape time as it uses minimal mechanical assistance to be launched allowing an early escape. Besides rescuing people from a dangerous situation, a lifeboat is also required to have essential survival equipment for the people on board the lifeboat to use to survive until they receive help.
There are three different types of lifeboats, each type serves a purpose and is partnered with a vessel that it is compatible with. The following are the three broad types:
Open Lifeboat
As the name suggests, the open lifeboat has no roof and is normally propelled by manual power by using hand-propelled ores. Compression ignition engine may also be provided for the propulsion purpose. However, open lifeboats are becoming obsolete now because of stringent safety norms, but one may find them on an older ship.
The open lifeboat doesn’t help much in rain or bad weather and the possibility of water ingress in the highest.
Closed Lifeboat
Closed lifeboats are the most popular lifeboats that are used on ships, for they are enclosed which saves the crew from seawater, strong wind and rough weather. Moreover, the watertight integrity is higher in this type of lifeboat and it can also get upright on its own if toppled over by waves.
Closed lifeboats are further classified as – Partially enclosed and fully enclosed lifeboats.
Free Fall Lifeboat
Freefall lifeboat is similar to an enclosed lifeboat but the process of launching is entirely different. They are aerodynamic in nature and thus the boat can penetrate the water without damaging the body when launched from the ship.
The free-fall lifeboat is located at the aft of the ship, which provides a maximum clear area for free fall.
