The Blue Riband is an unofficial accolade given to the passenger liner crossing the Atlantic Ocean in regular service with the record highest average speed. The term was borrowed from horse racing and was not widely used until after 1910. The record is based on average speed rather than passage time because ships follow different routes. Also, eastbound and westbound speed records are reckoned separately, as the more difficult westbound record voyage, against the Gulf Stream and the prevailing weather systems, typically results in lower average speeds.
SS Great Western of 1838, was a wooden-hulled paddle-wheel steamship with four masts, the first steamship purpose-built for crossing the Atlantic, and the initial unit of the Great Western Steamship Company. She was the largest passenger ship in the world from 1837 to 1839, the year the SS British Queen went into service.
Europa, later Liberté IMO 5607332, was a German ocean liner built for the Norddeutsche Lloyd line (NDL) to work the transatlantic sea route. She and her sister ship, Bremen, were the two most advanced, high-speed steam turbine ocean vessels in their day, with both earning the Blue Riband.
City of New York was a British built passenger liner of the Inman Line that was designed to be the largest and fastest liner on the Atlantic. When she entered service in August 1888, she was the first twin screw express liner and while she did not achieve the westbound Blue Riband, she ultimately held the eastbound record from August 1892 to May 1893 at a speed of 20.11 knots. City of New York and her sister City of Paris are considered especially beautiful ships and throughout their careers were rivals to the White Star Teutonic and Majestic. In February 1893, the Inman Line was merged into the American Line and by act of Congress, the renamed New York was transferred to the US flag. Beginning in the mid-1890s, New York and Paris were paired with St Louis and St Paul to form one of the premier Atlantic services. New York continued with the American Line until 1920 and was broken for scrap in 1923. She served the US Navy as Harvard during the Spanish–American War and Plattsburg in World War I. She is also remembered for nearly colliding with the RMS Titanic as the latter ship began her doomed maiden voyage in 1912.
The Inman Line was one of the three largest 19th-century British passenger shipping companies on the North Atlantic, along with the White Star Line and Cunard Line. Founded in 1850, it was absorbed in 1893 into American Line. The firm's formal name for much of its history was the Liverpool, Philadelphia and New York Steamship Company, but it was also variously known as the Liverpool and Philadelphia Steamship Company, as Inman Steamship Company, Limited, and, in the last few years before absorption, as the Inman and International Steamship Company.
The RMS Teutonic was an ocean liner built for the White Star Line in Belfast and was the first armed merchant cruiser.
SS Abyssinia was a British mail liner built in 1870, and originally operated by the Cunard Line on the Liverpool–New York route. She later served the Guion Line on the same route and the Canadian Pacific Line in the Pacific. In December 1891, Abyssinia was destroyed mid-Atlantic without loss of life by a fire that started in her cargo of cotton, further highlighting the danger in carrying both cotton and passengers on the same ship.
The Arizona was a record breaking British passenger liner that was the first of the Guion Line's Atlantic Greyhounds on the Liverpool-Queenstown-New York route. One nautical historian called Arizona "a souped up transatlantic hot rod." Entering service in 1879, she was the prototype for Atlantic express liners until the Inman Line introduced its twin screw City of New York in 1889. The Arizona type liner is generally considered as unsuccessful because too much was sacrificed for speed. Laid up in 1894 when Guion stopped sailings, Arizona was sold four years later and briefly employed in the Pacific until she was acquired by the US Government for service in the Spanish–American War. As the U.S. Navy's Hancock she continued trooping through W.W.I. and was finally scrapped in 1926.
City of Paris was a British passenger liner operated by the Inman Line that established that a ship driven by a screw could match the speed of the paddlers on the Atlantic crossing. Built by Tod and Macgregor, she served the Inman Line until 1884 when she was converted to a cargo ship.
City of Brussels was a British passenger liner that set the record for the fastest Atlantic eastbound voyage in 1869, becoming the first record breaker driven by a screw. Built by Tod and Macgregor, she served the Inman Line until 1883 when she sank with the loss of ten people after a collision while entering the Mersey.
City of Berlin was a British ocean liner that won the Blue Riband for the Inman Line in 1875 as the fastest liner on the Atlantic. She was also the largest active passenger ship for six years except for the inactive Great Eastern Built by Caird & Company in Scotland, City of Berlin was the Inman Line's premier unit for thirteen years until City of New York was commissioned in 1888. She served the Inman Line until 1893 when Inman was merged into the American Line, and she was operated by her new owners on both the American Line and Red Star Line until 1898. She was sold to the U.S. Government, and was in their service until after World War I.
The Liverpool and Great Western Steamship Company, known commonly as the Guion Line, was a British passenger service that operated the Liverpool-Queenstown-New York route from 1866 to 1894. While incorporated in Great Britain, 52% of the company's capital was from the American firm, Williams and Guion of New York. Known primarily for transporting immigrants, in 1879 the line started commissioning Blue Riband record breakers to compete against Cunard, White Star and Inman for first class passengers. The financial troubles of one of the company's major partners in 1884 forced the firm to return its latest record breaker, the Oregon, to her builders and focus again on the immigrant trade. The company suspended sailings in 1894 because of new American restrictions on immigrant traffic.
SS Oregon was a record-breaking British passenger liner that won the Blue Riband for the Guion Line as the fastest liner on the Atlantic in 1884. She was sold to the Cunard Line after a few voyages and continued to improve her passage times for her new owner. In 1885, Oregon was chartered to the Royal Navy as an auxiliary cruiser, and her success in this role resulted in the Admiralty subsidizing suitable ships for quick conversion in the event of a crisis. She returned to Cunard service in November 1885 and four months later collided with a schooner while approaching New York. Virtually all persons on board were rescued before Oregon sank. Her wreck, 18 miles south of Long Island, remains a popular diving site.
City of Rome was a British ocean liner, built by the Barrow Ship Building Company for the Inman Line to be the largest and fastest liner on the North Atlantic route. Though not achieving the requested specifications due to design compromise, and so returned to Barrow-in-Furness after only six voyages, she is considered one of the most beautiful steamships built, with her classic clipper bow and sail rigging illustrating the transitional period of sail to steam. The Anchor Line managed her on various routes until 1900. She was scrapped in 1902.
Scotia was a British passenger liner operated by the Cunard Line that won the Blue Riband in 1863 for the fastest westbound transatlantic voyage. She was the last oceangoing paddle steamer, and as late as 1874 she made Cunard's second fastest voyage. Laid up in 1876, Scotia was converted to a twin-screw cable layer in 1879. She served in her new role for twenty-five years until she was wrecked off of Guam in March 1904.
Persia was a British passenger liner operated by the Cunard Line that won the Blue Riband in 1856 for the fastest westbound transatlantic voyage. She was the first Atlantic record breaker constructed of iron and was the largest ship in the world at the time of her launch. However, the inefficiencies of paddle wheel propulsion rendered Persia obsolete and she was taken out of service in 1868 after only twelve years. Attempts to convert Persia to sail were unsuccessful and the former pride of the British merchant marine was scrapped in 1872.
The America class was the replacement for the Britannia class, the Cunard Line's initial fleet of wooden paddle steamers. Entering service starting in 1848, these six vessels permitted Cunard to double its schedule to weekly departures from Liverpool, with alternating sailings to New York. The new ships were also designed to meet new competition from the United States.
The first Saxonia was a passenger ship of the British Cunard Line. Between 1900 and 1925, Saxonia operated on North Atlantic and Mediterranean passenger routes, and she saw military service during World War I (1914–1918).
SS Parthia (1870–1956) was an iron-hulled transatlantic ocean liner built for the Cunard Line by William Denny and Brothers in Dumbarton, Scotland. Her sister ships were the Abyssinia and Algeria. Unlike her two sisters, Parthia was smaller, built in a different shipyard and had a slightly different funnel arrangement. The Parthia was retired by Cunard in 1883 and sold to John Elder & Co., who subsequently transferred her to the Guion Line. After serving with the Guion Line and operating on trans-Pacific routes with the Canadian Pacific Railway Company, she was refitted and renamed Victoria.
The Teutonic-class ocean liners were a pair of passenger liners named the Teutonic and Majestic. these ship were built by Harland & Wolff shipyard for the White Star Line, specifically for the White Star Line's transatlantic service route. These ships are also renowned as revolutionary for the time, as their main propulsion are propellers instead of square-rigged sails.
