Definition

•A lifeboat is a small, rigid or inflatable watercraft carried for emergency evacuation in the event of a disaster aboard ship. (Example : Collision, engine room explosion or fire, shifting of cargos that is hazardly making the vessel unbalance, act of sea pirates)

•Under regulation of SOLAS, it is essential for passenger ships to have a lifeboat with capacity of generally sufficient for every person on board

•For cargo ships the capacity of the life boat is generally twice the number of persons on board

•Note : abandon ship is the last resort. Always remember that the mothership is the safeties vessel for you. 

Origin of the Lifeboat

•A collapsible lifeboat carrying survivors of the sunken RMS Titanic.

•By the turn of the 20th century larger ships meant more people could travel, but safety rules in regard with lifeboats stayed out of date - for example, British legislation concerning the number of lifeboats was based on the tonnage of a vessel and only encompassed vessels of "10,000 gross tons and over". It was after the sinking of the RMS Titanic on April 15, 1912, that a movement began to require a sufficient number of lifeboats on passenger ships for all people on board. The Titanic, with a gross tonnage of 46,000 tonnes and carrying 20 lifeboats, met and exceeded the regulations laid down by the Board Of Trade, which required a ship of her size (i.e. over 10,000 tons) to carry boats capable of carrying a total of 1,060 people. The Titanic's boats had a capacity of 1,178 people on a ship capable of carrying 3,330 people.

•The need for so many more lifeboats on the decks of passenger ships after 1912 led to the use of most of the deck space available even on the large ships, creating the problem of restricted passageways. This was resolved by the introduction of collapsible lifeboats, a number of which had been carried on the Titanic.

•During World War Two and the Battle of the Atlantic with convoys going to norther Russia through the Arctic Ocean it was found that the chance of the crews of merchant ships surviving in open lifeboats was not very good unless they were rescued in a couple of hours. The US Navy asked various groups and manufactures to suggest solutions. The results was the first enclosed, unsinkable, self-righting lifeboat that was manufactured in Delanco, New Jersey, USA. The first units were delivered in 1944. These new radical lifeboats were 24 foot in length and weighed 5,000 lbs. They had two enclosed cabins at each end which could hold a total of 25 persons. The space in between was designed to help persons in the water be pulled aboard and could be enclosed with a canvas top. The new type lifeboat could be drive either by a small motor or sail.

•Also, in 1943 the US developed a balsa wood liferaft that would not sink, no matter the number of holes in it. These balsa liferafts were designed to hold five to ten men on a platform suspend on the inside or fifteen to twenty-five hanging lines placed on the outsides. They were cheap and during the war thousands were stored in any space possible on US warship and merchant ships. These liferafts were intended only for use during a short term before lifeboats or another ship in the convoy or group could bring them aboard. When the USS Indianapolisoperating alone was sunk in 1945, none of its larger lifeboats were launched and instead the survivors had to rely these balsa liferafts which were automatically released as the ship sank. While many of the crew perished if it had not been for these type of balsa liferafts it is likely all would have perished.
