An ocean liner is a type of passenger ship primarily used for transportation across seas or oceans. Ocean liners may also carry cargo or mail, and may sometimes be used for other purposes. Only one ocean liner remains in service today.
RMS Laconia was a Cunard ocean liner, built by Swan, Hunter & Wigham Richardson as a successor of the 1911–1917 Laconia. The new ship was launched on 9 April 1921, and made her maiden voyage on 25 May 1922 from Southampton to New York City. At the outbreak of the Second World War she was converted into an armed merchant cruiser, and later a troopship. She was sunk in the South Atlantic Ocean on 12 September 1942 by torpedoes. Like her predecessor, sunk during the First World War, this Laconia was also destroyed by a German submarine. Some estimates of the death toll have suggested that over 1,658 people were killed when the Laconia sank. The U-boat commander Werner Hartenstein then staged a dramatic effort to rescue the passengers and the crew of Laconia, which involved additional German U-boats and became known as the Laconia incident.
RMS Republic was a steam-powered ocean liner built in 1903 by Harland and Wolff in Belfast, and lost at sea in a collision in 1909 while sailing for the White Star Line. The ship was equipped with a new Marconi wireless telegraphy transmitter, and issued a CQD distress call, resulting in the saving of around 1,500 lives. Known as the "Millionaires' Ship" because of the number of wealthy Americans who traveled by her, she was described as a "palatial liner" and was the flagship of White Star Line's Boston service. This was the first important marine rescue made possible by radio, and brought worldwide attention to this new technology.
British India Steam Navigation Company ("BI") was formed in 1856 as the Calcutta and Burmah Steam Navigation Company.
The SS City of Rio de Janeiro was an iron-hulled steam-powered passenger ship, launched in 1878, which sailed between San Francisco and various Asian Pacific ports. On 22 February 1901, the vessel sank after striking a submerged reef at the entry to San Francisco Bay while inward bound from Hong Kong. Of the approximately 220 passengers and crew on board, fewer than 85 people survived the sinking, while 135 others were killed in the catastrophe. The wreck lies in 287 feet (87 m) of water just off the Golden Gate and is listed in the National Register of Historic Places as nationally significant.
P Henderson & Company, also known as Paddy Henderson, was a ship owning and management company based in Glasgow, Scotland and operating to Burma. Patrick Henderson started business in Glasgow as a merchant at the age of 25 in 1834. He had three brothers. Two were merchants working for an agent in the Italian port of Leghorn; the third, George, was a sea captain with his own ship.
SS Laurentic was a British transatlantic ocean liner that was built in Belfast, Ireland, and launched in 1908. She is an early example of a ship whose propulsion combined reciprocating steam engines with a low-pressure steam turbine. Laurentic was one of a pair of sister ships that were ordered in 1907 by the Dominion Line but completed for the White Star Line. Her regular route was between Liverpool and Quebec City.
HMS Truant (N68) was a T-class submarine of the Royal Navy. She was laid down by Vickers Armstrong, Barrow and launched on 5 May 1939.
RMS Carpathia was a Cunard Line transatlantic passenger steamship built by Swan Hunter & Wigham Richardson in their shipyard in Wallsend, England.
SS City of Cairo was a British passenger steamship. She was sunk in the Second World War with heavy loss of life, most after the sinking, but before being rescued.
I-27 was a submarine of the Imperial Japanese Navy which saw service during the Pacific Campaign of World War II. I-27 was commissioned at Sasebo, Japan on February 24, 1942 and sunk on February 12, 1944, after torpedoing the troopship SS Khedive Ismail.
SS Mantola was a British India Steam Navigation Company (BI) steamship that was built in 1916 and sunk by a German U-boat in 1917. She belonged to BI's "M" class of cargo liners. She was carrying an estimated 600,000 ounces of silver bullion when she was sunk. In 2017, 526 bars of silver were salvaged from the wreck and taken to the United Kingdom, in circumstances that remain undisclosed.
"The captain goes down with the ship" is a maritime tradition that a sea captain holds the ultimate responsibility for both the ship and everyone embarked on it, and in an emergency they will devote their time to save those on board or die trying. Although often connected to the sinking of RMS Titanic in 1912 and its captain, Edward Smith, the tradition precedes Titanic by several years. In most instances, captains forgo their own rapid departure of a ship in distress, and concentrate instead on saving other people. It often results in either the death or belated rescue of the captain as the last person on board.
SS Egypt was a P&O ocean liner. She sank after a collision with Seine on 20 May 1922 in the Celtic Sea. 252 people were rescued from the 338 passengers and crew aboard at the time. A subsequent salvage operation recovered most of the cargo of gold and silver.

SS Sagaing was a twin-hatched passenger and cargo steamship that regularly plied a route connecting Liverpool, Glasgow and Rangoon in the first half of the 20th century. It was attacked and partially destroyed at Trincomalee Harbour by aircraft of the Imperial Japanese Navy in 1942, as part of the Easter Sunday Raid on Ceylon. The hulk was sunk a year later to act as a pier but was raised in 2018 after a 5-month operation by the Sri Lanka Navy, moved out of the harbour area, and resunk.
Recreational dive sites are specific places that recreational scuba divers go to enjoy the underwater environment or for training purposes. They include technical diving sites beyond the range generally accepted for recreational diving. In this context all diving done for recreational purposes is included. Professional diving tends to be done where the job is, and with the exception of diver training and leading groups of recreational divers, does not generally occur at specific sites chosen for their easy access, pleasant conditions or interesting features.
I-64 was an Imperial Japanese Navy Kaidai-class cruiser submarine of the KD4 sub-class commissioned in 1930. During World War II, she supported the Japanese invasion of Malaya and conducted war patrols in the Indian Ocean before she was sunk in May 1942 while deploying to take part in the upcoming Battle of Midway. Just after her loss, and before her loss became known to the Japanese, she was renumbered I-164.
