Great Balance Dock
The Great Balance Dock was a floating drydock in New York City. It was the largest such facility in the world when constructed in 1854, and consequently, many of the most important ships of its time were serviced there. Construction and Characteristics The underwater portions of ship's hulls require periodic maintenance. This includes removing marine growth from the hull, and repairing rudders. For the wooden ships of the nineteenth century, hull maintenance included caulking between hull planks, and nailing thin copper sheets to the bottom to discourage marine growth and wood-boring marine worms. Propeller-driven vessels required work on the propellers themselves and the associated bearings, shafts, and stuffing boxes. Hulls damaged in storms, collisions, groundings, or by the action of worms or rot also needed work below their waterlines. It has always been difficult to access the underwater portions of a ship's hull. From earliest times this was achieved by careeni ...

Russian Frigate General Admiral
} ''General Admiral'' (russian: Генерал-адмирал) was a screw frigate ordered by the Imperial Russian Navy from the United States before the American Civil War. She spent the bulk of her career in the Mediterranean Sea where she evacuated insurgents and their families from Crete in 1868 during the Cretan Revolt. She was struck from the Navy List the following year and broken up in 1870. Description ''General Admiral'' was a very large screw frigate designed by Captain 1st Rank Ivan Shestakov and named after General Admiral Grand Duke Konstantin Nikolayevich of Russia, commander of the Russian Navy. She was built of live oak, but was reinforced with diagonal and longitudinal iron braces.Drashpil, p. 226 ''General Admiral'' displaced . She was long between perpendiculars, had a beam of and a deep draft of .Tredea & Sozaev, p. 412 She was sheathed in copper to reduce biofouling.

East River
The East River is a saltwater tidal estuary in New York City. The waterway, which is actually not a river despite its name, connects Upper New York Bay on its south end to Long Island Sound on its north end. It separates the borough of Queens on Long Island from the Bronx on the North American mainland, and also divides Manhattan from Queens and Brooklyn, also on Long Island.Hodges, Godfrey. "East RIver" in Jackson, pp.393–93 Because of its connection to Long Island Sound, it was once also known as the ''Sound River''. The tidal strait changes its direction of flow frequently, and is subject to strong fluctuations in its current, which are accentuated by its narrowness and variety of depths. The waterway is navigable for its entire length of , and was historically the center of maritime activities in the city. Formation and description Technically a drowned valley, like the other waterways around New York City, the strait was formed approximately 11,000 years ago at ...

Strake
On a vessel's hull, a strake is a longitudinal course of planking or plating which runs from the boat's stempost (at the bows) to the sternpost or transom (at the rear). The garboard strakes are the two immediately adjacent to the keel on each side. The word derives from traditional wooden boat building methods, used in both carvel and clinker construction. In a metal ship, a strake is a course of plating. Construction In small boats strakes may be single continuous pieces of wood. In larger wooden vessels strakes typically comprise several planks which are either scarfed, or butt-jointed and reinforced with a butt block. Where the transverse sections of the vessel's shape are fuller, the strakes are wider; they taper toward the ends. In a riveted steel ship, the strakes were usually lapped and joggled (one strake given projections to match indentions in the one adjoining), but where a smoother finish was sought they might be riveted on a butt strap, though this was ...

Knee (construction)
In woodworking, a knee is a natural or cut, curved piece of wood. Knees, sometimes called ships knees, are a common form of bracing in boat building and occasionally in timber framing. A knee rafter in carpentry is a bent rafter used to gain head room in an attic. Strength characteristics Wood is a highly anisotropic material (its strength varies considerably with the direction of applied force, i.e. parallel, radial, or tangential to the grain). Because wood is strongest when loaded in tension or compression along the grain, the best knees are those in which the wood grain follows the bend. For a knee with relatively little bend, it may be possible to cut the knee out of a single straight-grained board and still achieve sufficient strength. However, with increasing bend this method becomes problematic since more and more of the knee is aligned across the grain and is therefore considerably weaker. A knee laid out this way might easily snap in two under hand pressure alone, even ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SS Fulton (1855)
The ''Fulton'' was a wooden hulled, brig-rigged, sidewheel steamer built in 1855 by the Smith and Dimon Shipyard at New York City for the New York & Havre Steam Navigation Company. She was chartered by the Union Army in the Army Transport Service, during the American Civil War. She returned to transatlantic passenger and freight service after the Civil War. Construction The ''Fulton'' was built in 1855, by Smith and Dimon Shipyard of New York. She was launched on September 4, 1855. Her sister ship ''Arago'' was built by Westervelt & Sons. They were both constructed in 1855 for the New York & Havre Steam Navigation Company, then under contract with the United States Government to deliver mail between New York and Le Havre, France. Both were named for steamship pioneers. ''Fultons namesake was Robert Fulton (1765–1815), an American engineer and inventor. Both were considered great improvements to their predecessors of the era. Their design included oscillating engines, water t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SS Baltic (1850)
SS ''Baltic'' was a wooden-hulled sidewheel steamer built in 1850 for transatlantic service with the American Collins Line. Designed to outclass their chief rivals from the British-owned Cunard Line, ''Baltic'' and her three sister ships—''Atlantic'', and —were the largest, fastest and most luxurious transatlantic steamships of their day. Less than a year after entering service, ''Baltic'' captured the coveted Blue Riband in 1851 for fastest transatlantic crossing by a steamship. She set a new record again in 1854, and was to remain the fastest steamship on the Atlantic for almost five years. In spite of these record-breaking achievements however, her Collins Line owners continued to lose money, and were eventually bankrupted in 1858. ''Baltic'' subsequently operated as a coastal steamer along the East Coast of the United States, and later served as a transport for the Union cause during the American Civil War before briefly returning to transatlantic service. In her final y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SS Arago (1855)
The ''Arago'' was a wooden hulled, brig-rigged, sidewheel steamer built in 1855 by Westervelt & Sons at New York, New York. Chartered by the Union Army in the Army Transport Service, during the American Civil War for use as a troop transport and in operation with the South Atlantic Blockading Squadron throughout the war, ''Arago'' was the ship that returned the United States flag to Fort Sumter in April 1865. Returned to transatlantic passenger and freight service after the Civil War, she was sold to the Peruvian government in 1869. Construction The ''Arago'', built by Westervelt and Sons, and her sister ship SS ''Fulton'' launched 4 September 1855, built by Smith and Dimon of New York, were constructed in 1855 for the New York & Havre Steam Navigation Company, then under contract with the United States Government to deliver mail between New York and Havre. Both named for steamship pioneers, ''Aragos namesake was François Arago (1786–1853), a French physicist. Considered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hamburg America Line
The Hamburg-Amerikanische Packetfahrt-Aktien-Gesellschaft (HAPAG), known in English as the Hamburg America Line, was a transatlantic shipping enterprise established in Hamburg, in 1847. Among those involved in its development were prominent citizens such as Albert Ballin (Director General), Adolph Godeffroy, Ferdinand Laeisz, Carl Woermann, August Bolten, and others, and its main financial backers were Berenberg Bank and H. J. Merck & Co. It soon developed into the largest German, and at times the world's largest, shipping company, serving the market created by German immigration to the United States and later, immigration from Eastern Europe. On 1 September 1970, after 123 years of independent existence, HAPAG merged with the Bremen-based North German Lloyd to form Hapag-Lloyd AG. History Ports served In the early years, the Hamburg America Line exclusively connected European ports with North American ports, such as Hoboken, New Jersey, or New Orleans, Louisiana. With time ...

Dry Dock
A dry dock (sometimes drydock or dry-dock) is a narrow basin or vessel that can be flooded to allow a load to be floated in, then drained to allow that load to come to rest on a dry platform. Dry docks are used for the construction, maintenance, and repair of ships, boats, and other watercraft. History Greco-Roman world The Greek author Athenaeus of Naucratis (V 204c-d) reports something that may have been a dry dock in Ptolemaic Egypt in the reign of Ptolemy IV Philopator (221-204 BC) on the occasion of the launch of the enormous '' Tessarakonteres'' rowing ship. It has been calculated that a dock for a vessel of such a size might have had a volume of 750,000 gallons of water. In Roman times, a shipyard at Narni, which is still studied, may have served as a dry dock. Medieval China The use of dry docks in China goes at least as far back the 10th century A.D. In 1088, Song Dynasty scientist and statesman Shen Kuo (1031–1095) wrote in his '' Dream Pool Essays'': Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A Sectional View Of The Great Balance Drydock
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it fr ...
