SS Agamemnon was one of the first successful long-distance merchant steamships. She was built in 1865 to trade between Britain and China, and competed with tea clippers before and after the opening of the Suez Canal in 1869. She brought together three improvements in steamship design: higher boiler pressure, an efficient and compact compound steam engine, and a hull form with modest power requirements.
Before Agamemnon, steamships were not a practical commercial option for trade between Britain and the Far East. The amount of coal that they needed to carry left little space for cargo. Agamemnon could steam at 10 knots (19 km/h), consuming only 20 tons of coal a day. This was substantially less than other ships of the time –a saving of between 14 and 23 tons per day was achieved. [1] This enabled her to steam to China with a coaling stop at Mauritius on the outward and return journey.
This was the first of five Blue Funnel ships to be named after Agamemnon, the king of Mycenae during the Trojan War. Later examples include a motor ship Agamemnon built in 1929, which in the Second World War was converted into an auxiliary minelayer.
Agamemnon was the first of three sister ships, the others being Achilles (1866) and Ajax (1867). Scott & Co of Greenock, Renfrewshire built the three ships for Alfred and Phillip Holt's Ocean Steam Ship Company, later called the Blue Funnel Line. Each was 2,270 GRT and 1,550 NRT. Overall length was 309 feet (94 m) and beam 38 feet (12 m). [2]
Agamemnon (and her sister ships) combined three key features.
The first was a higher boiler pressure than was normally used on British merchant ships. Alfred Holt had experimented with a boiler pressure of 60 psi in the Cleator, a ship he used as a floating testbed. Holt overcame the Board of Trade's objections to boiler pressures above 25 psi in seagoing vessels.
The second feature was her compound steam engine, designed by Alfred Holt. As well as being more efficient than others of the time, it was a relatively compact engine, so used less cargo space.
The third was an iron hull that was strong in relation to its weight and cost and with modest power requirements –again developed by Alfred Holt. [1]
Agamemnon's fuel efficiency enabled her to compete successfully with tea clippers between Britain and China. She could steam from London to Mauritius, a distance of 8,500 miles (roughly half the distance to China via the Cape of Good Hope) without coaling.
Her normal journey time from Fuzhou (Foochow) to Liverpool was 58 days, [3] [2] whereas clippers could take anything from a record-breaking 88 days to 140 or more, and averaged 123 days in 1867–68. [4] Further, her cargo carrying capacity was two or three times as much as these sailing ships. [2]
Scott built Agamemnon as yard number 116, launched her on 25 November 1865 and completed her on 31 March 1866. [5] Alfred Holt registered her at Liverpool. Her UK official number was 54924, [6] and by 1871 her code letters were JKGB. [7]
The newly built Agamemnon arrived in Liverpool from Greenock on 1 April 1866, the year of the clippers' Great Tea Race. She sailed for China on 19 April. [8] Her outward passage was the quickest recorded to date, reaching Mauritius in 40 days and Singapore in 60. The whole journey from Liverpool to Hong Kong took 65 days. [9] This beat the fastest tea clipper outward passage of 77 days by the Cairngorm in 1853.
The opening of the Suez Canal in 1869 guaranteed the success of Agamemnon and her sister ships by shortening the route that a steamship could take from Europe to China whilst sailing vessels still had to travel via the Cape of Good Hope. In a few years the predominance of tea clippers in the China trade had ceased. Associates and competitors of Alfred Holt built similar ships and the nature of long-distance maritime trade had taken a major technological change.
In 1897 Agamemnon was transferred to Alfred Holt's Dutch subsidiary Nederlandsche Stoomboot Maatschappij Ocean. She was scrapped in 1899.
A clipper was a type of mid-19th-century merchant sailing vessel, designed for speed. The term was also retrospectively applied to the Baltimore clipper, which originated in the late 18th century.
A steamship, often referred to as a steamer, is a type of steam-powered vessel, typically ocean-faring and seaworthy, that is propelled by one or more steam engines that typically move (turn) propellers or paddlewheels. The first steamships came into practical usage during the early 1800s; however, there were exceptions that came before. Steamships usually use the prefix designations of "PS" for paddle steamer or "SS" for screw steamer. As paddle steamers became less common, "SS" is incorrectly assumed by many to stand for "steamship". Ships powered by internal combustion engines use a prefix such as "MV" for motor vessel, so it is not correct to use "SS" for most modern vessels.
Cutty Sark is a British clipper ship. Built on the River Leven, Dumbarton, Scotland in 1869 for the Jock Willis Shipping Line, she was one of the last tea clippers to be built and one of the fastest, at the end of a long period of design development for this type of vessel, which ended as steamships took over their routes. She was named after the short shirt of the fictional witch in Robert Burns' poem Tam o' Shanter, first published in 1791.
SS Carnatic was a British steamship built in 1862-63 by Samuda Brothers at Cubitt Town on the Isle of Dogs, London, for the Peninsular and Oriental Steam Navigation Company (P&O). She operated on the Suez to Bombay run in the last years before the Suez Canal was opened. This route gave a fast, steamship-operated route from Britain to India, connecting with similar steamships running through the Mediterranean to Alexandria, with an overland crossing to Suez. The alternative was to sail round the Cape of Good Hope, a distance at which steam ships were not, in the early 1860s, sufficiently economical to be commercially competitive with sail.
A steamboat is a boat that is propelled primarily by steam power, typically driving propellers or paddlewheels. Steamboats sometimes use the prefix designation SS, S.S. or S/S or PS ; however, these designations are most often used for steamships.
Thermopylae was an extreme composite clipper ship built in 1868 by Walter Hood & Co of Aberdeen, to the design of Bernard Waymouth of London. Designed for the China tea trade, she set a speed record on her maiden voyage to Melbourne of 63 days, still the fastest trip under sail.
The Age of Sail is a period that lasted at the latest from the mid-16th to the mid-19th centuries, in which the dominance of sailing ships in global trade and warfare culminated, particularly marked by the introduction of naval artillery, and ultimately reached its highest extent at the advent of the analogue Age of Steam. Enabled by the advances of the related Age of Navigation, it is identified as a distinctive element of the early modern period and the Age of Discovery. Especially in context of the latter, it refers to a more particular Eurocentric Age of Sail, while generally the Age of Sail is the culminating period of a long intercontinental history of sailing.
Ariel was a clipper ship famous for making fast voyages between China and England in the late 1860s. She is most famous for almost winning The Great Tea Race of 1866, an unofficial race between Fuzhou, China and London with the first tea crop of the 1866 season.
Sir Lancelot was a clipper ship which sailed in the China trade and the India-Mauritius trade.
Alfred Holt and Company, trading as Blue Funnel Line, was a UK shipping company that was founded in 1866 and operated merchant ships for 122 years. It was one of the UK's larger shipowning and operating companies, and as such had a significant role in the country's overseas trade and in the First and Second World Wars.
The Taeping was a tea clipper built in 1863 by Robert Steele & Company of Greenock and owned by Captain Alexander Rodger of Cellardyke, Fife. Over her career, Taeping was the first clipper to dock in London in three different tea seasons. This compares with the highly successful Fiery Cross, who won the "premium" in four separate tea seasons.
In the middle third of the 19th century, the clippers which carried cargoes of tea from China to Britain would compete in informal races to be first ship to dock in London with the new crop of each season. The Great Tea Race of 1866 was keenly followed in the press, with an extremely close finish. Taeping docked 28 minutes before Ariel - after a passage of more than 14,000 miles. Ariel had been ahead when the ships were taken in tow by steam tugs off Deal, but after waiting for the tide at Gravesend the deciding factor was the height of tide at which one could enter the different docks used by each ship. The third finisher, Serica, docked an hour and 15 minutes after Ariel. These three ships had left China on the same tide and arrived at London 99 days later to dock on the same tide. The next to arrive, 28 hours later, was Fiery Cross, followed, the next day, by Taitsing.
Flying Spur was a British tea clipper, built of teak and greenheart in 1860.
The SS Erl King was built at A and J Inglis, Pointhouse, Glasgow and launched in 1865 and owned by Robertson & Co London. She was designed as an Auxiliary Steam Ship - steam power would be used to supplement the propulsion from the sails, when there was no wind or if there was a light head wind. She was fitted with a propeller that could be lifted up when sailing, so as to reduce drag. The engine was not powerful enough to push the ship, with all the windage of standing rigging, directly into a strong headwind. Auxiliary steam power had the advantage of allowing this vessel to use the Suez Canal when it opened in 1869 - something which was not possible for sailing vessels.
Alfred Holt was a British engineer, ship owner and merchant. He lived at Crofton, Sudley Road, Aigburth in Liverpool, England. Holt is credited with establishing the long distance steamship by developing a type that replaced sailing clippers on the route from Britain to China.
Windhover was a British tea clipper built in the closing years of construction of this sort of ship. She measured 847 tons NRT. Like the majority of the tea clippers built in the second half of the 1860s, she was of composite construction. She was built by Connell and Co, Glasgow, Scotland in 1868.
SS Aberdeen was a British cargo liner launched in 1882. She was designed for service from London to Australia. She was the first ship to be successfully powered by a triple expansion steam engine. The triple expansion engine then became the standard type of steam engine to be installed in seagoing vessels. The fuel economy achieved meant that steam could now outcompete sail on all major commercial routes.
Lamport and Holt was a UK merchant shipping line. It was founded as a partnership in 1845, reconstituted as a limited company in 1911 and ceased trading in 1991.
The Far Eastern Freight Conference was a co-operative agreement between a group of steamship owners and shipbrokers involved in scheduled cargo liner services principally between China and Japan, and European ports. It was established in 1879 as the China and Japan Conference through the efforts of John Swire. They co-operated in order to overcome excess capacity of steamers in that trade. Described by some as a cartel, the conference rewarded shippers that gave all their business to ships owned by conference members through a system of deferred rebates to the freight rates charged. These discounts were deferred for, typically, six months and were not payable if the shipper used a ship outside the conference in that time. Capacity was controlled by limiting each member to an agreed number of sailings during the year. The conference survived a legal challenge in 1885, which went to the High Court in 1887, then through the Court of Appeal and ultimately to the House of Lords: the conference won at every level. There were later challenges and enquiries, which the conference survived. Ultimately, changes to the European Union exemption of shipping conferences from their competition regulations brought the conference to an end in October 2008.
In the middle third of the 19th century, the clippers which carried cargoes of tea from China to Britain would compete in informal tea races to be first ship to dock in London with the new crop of each season. These races were also known as the races from China. The consignees of these cargoes wanted to be first in the market with this new crop, so they started to offer a "premium" to a ship that was the first to dock in London in that tea season.
