Clara Clarita
''Clara Clarita'' was a fast propeller, screw steamship, steamer originally built as a luxury steam yacht for New York City financier Leonard Jerome (grandfather of Prime Minister of the United Kingdom, British Prime Minister Sir Winston Churchill). On her trial trip, ''Clara Clarita''s original engine proved so ineffective it was removed before the vessel entered service and replaced by machinery from a different supplier. Jerome sold the yacht after only a short time and she was converted into a towboat, becoming the fastest such vessel in New York Harbor, before being converted into a fireboat in the same locality. In the 1870s, ''Clara Clarita'' underwent a third conversion, into a passenger steamer, in which role she set an all-time speed record for a steamer on Penobscot Bay. Her final conversion was into an oceangoing tug, some time after which her crew and captain were presented with a heroism award for a rescue at sea. The vessel was abandoned in 1908 after a long and var ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SS Clara Clarita
The ''Schutzstaffel'' (; ; SS; also stylised with SS runes as ''ᛋᛋ'') was a major paramilitary organisation under Adolf Hitler and the Nazi Party in Nazi Germany, and later throughout German-occupied Europe during World War II. It began with a small guard unit known as the ''Saal-Schutz'' ("Hall Security") made up of party volunteers to provide security for party meetings in Munich. In 1925, Heinrich Himmler joined the unit, which had by then been reformed and given its final name. Under his direction (1929–1945) it grew from a small paramilitary formation during the Weimar Republic to one of the most powerful organisations in Nazi Germany. From the time of the Nazi Party's rise to power until the regime's collapse in 1945, the SS was the foremost agency of security, mass surveillance, and state terrorism within Germany and German-occupied Europe. The two main constituent groups were the ''Allgemeine SS'' (General SS) and ''Waffen-SS'' (Armed SS). The ''Allgemeine SS' ...

Yacht
A yacht () is a sail- or marine propulsion, motor-propelled watercraft made for pleasure, cruising, or racing. There is no standard definition, though the term generally applies to vessels with a cabin intended for overnight use. To be termed a , as opposed to a , such a pleasure vessel is likely to be at least in length and may have been judged to have good aesthetic qualities. The Commercial Yacht Code classifies yachts and over as . Such yachts typically require a hired crew and have higher construction standards. Further classifications for large yachts are : carrying no more than 12 passengers; : solely for the pleasure of the owner and guests, or by Flag#At sea, flag, the country under which it is registered. A superyacht (sometimes ) generally refers to any yacht (sail or power) longer than . Racing yachts are designed to emphasize performance over comfort. Charter yachts are run as a business for profit. As of 2020, there were more than 15,000 yachts of sufficient size ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bow (nautical)
The bow () is the forward part of the hull of a ship or boat, the point that is usually most forward when the vessel is underway. The aft end of the boat is the stern. Prow may be used as a synonym for bow or it may mean the forward-most part of the bow above the waterline. Function A ship's bow should be designed to enable the hull to pass efficiently through the water. Bow shapes vary according to the speed of the boat, the seas or waterways being navigated, and the vessel's function. Where sea conditions are likely to promote pitching, it is useful if the bow provides reserve buoyancy; a flared bow (a raked stem with flared topsides) is ideal to reduce the amount of water shipped over the bow. Ideally, the bow should reduce the resistance and should be tall enough to prevent water from regularly washing over the top of it. Large commercial barges on inland waterways rarely meet big waves and may have remarkably little freeboard at the bow, whereas fast military ves ...

Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer sides of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a cora ...

Keel
The keel is the bottom-most longitudinal structural element of a watercraft, important for stability. On some sailboats, it may have a fluid dynamics, hydrodynamic and counterbalancing purpose as well. The keel laying, laying of the keel is often the initial step in constructing a ship. In the British and American shipbuilding traditions, this event marks the beginning date of a ship's construction. Etymology The word "keel" comes from Old English language, Old English , Old Norse , = "ship" or "keel". It has the distinction of being regarded by some scholars as the first word in the English language recorded in writing, having been recorded by Gildas in his 6th century Latin work ''De Excidio et Conquestu Britanniae'', under the spelling ''cyulae'' (he was referring to the three ships that the Saxons first arrived in). is the Latin word for "keel" and is the origin of the term careening, careen (to clean a keel and the hull in general, often by rolling the ship on its side).

Mahogany
Mahogany is a straight- grained, reddish-brown timber of three tropical hardwood species of the genus ''Swietenia'', indigenous to the AmericasBridgewater, Samuel (2012). ''A Natural History of Belize: Inside the Maya Forest''. Austin: University of Texas Press. pp. 164–165. . and part of the pantropical chinaberry family, Meliaceae. Mahogany is used commercially for a wide variety of goods, due to its coloring and durable nature. It is naturally found within the Americas, but has also been imported to plantations across Asia and Oceania. The mahogany trade is believed to have started as early as the 16th century and flourished throughout the 17th and 18th centuries. In some countries, mahogany is classified as an invasive species. Mahogany is wood from any of three tree species: Honduran or big-leaf mahogany ('' Swietenia macrophylla''), West Indian or Cuban mahogany ('' Swietenia mahagoni''), and '' Swietenia humilis''. Honduran mahogany is the most widespread and the only g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Oak
''Quercus'' subgenus ''Quercus'' is one of the two subgenera into which the genus ''Quercus'' was divided in a 2017 classification (the other being subgenus ''Cerris''). It contains about 190 species divided among five sections. It may be called the New World clade or the high-latitude clade; most species are native to the Americas, the others being found in Eurasia and northernmost North Africa. Description Members of subgenus ''Quercus'' are distinguished from members of subgenus ''Cerris'' by few morphological features, their separation being largely determined by molecular phylogenetic evidence. All are trees or shrubs bearing acorn-like fruit in which a cup covers at least the base of the nut. The outer structure of the mature pollen is one feature that distinguishes the two subgenera: in subgenus ''Quercus'', the small folds or wrinkles (rugulae) are obscured by sporopollenin, whereas in subgenus ''Cerris'', the rugulae are visible or at most weakly obscured. The two sub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientific American
''Scientific American'', informally abbreviated ''SciAm'' or sometimes ''SA'', is an American popular science magazine. Many scientists, including Albert Einstein and Nikola Tesla, have contributed articles to it, with more than 150 Nobel Prize-winners being featured since its inception. In print since 1845, it is the oldest continuously published magazine in the United States. ''Scientific American'' is owned by Springer Nature, which is a subsidiary of Holtzbrinck Publishing Group. History ''Scientific American'' was founded by inventor and publisher Rufus Porter (painter), Rufus Porter in 1845 as a four-page weekly newspaper. The first issue of the large-format New York City newspaper was released on August 28, 1845. Throughout its early years, much emphasis was placed on reports of what was going on at the United States Patent and Trademark Office, U.S. Patent Office. It also reported on a broad range of inventions including perpetual motion machines, an 1860 devi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Williamsburg, Brooklyn
Williamsburg is a neighborhood in the New York City borough of Brooklyn, bordered by Greenpoint to the north; Bedford–Stuyvesant to the south; Bushwick and East Williamsburg to the east; and the East River to the west. It was an independent city until 1855, when it was annexed by Brooklyn; at that time, the spelling was changed from Williamsburgh (with an "h") to Williamsburg. Williamsburg, especially near the waterfront, was a vital industrial district until the mid-20th century. As many of the jobs were outsourced beginning in the 1970s, the area endured a period of economic contraction which did not begin to turn around until activist groups began to address housing, infrastructure, and youth education issues in the late 20th century. An ecosocial arts movement emerged alongside the activists in the late 1980s, often referred to as the Brooklyn Immersionists.The Williamsburg Avant-Garde: Experimental Music and Sound on the Brooklyn Waterfront by Cisco Bradley, Duke Uni ...

Fireboat
A fireboat or Fire-float Pyronaut, fire-float is a specialized watercraft with pumps and nozzles designed for fighting shoreline and shipboard fires. The first fireboats, dating to the late 18th century, were tugboats, retrofitted with firefighting equipment. Older designs derived from tugboats and modern fireboats more closely resembling seafaring ships can both be found in service today. Some departments would give their multi-purpose craft the title of "fireboat" also. They are frequently used for firefighting, fighting fires on Dock (maritime), docks and shore side warehouses as they can directly attack fires in the supporting underpinnings of these structures. They also have an effectively unlimited supply of water available, pumping directly from below the hull. Fireboats can be used to assist shore-based firefighters when other water is in low supply or is unavailable, for example, due to earthquake breakage of water mains, as happened in San Francisco due to the ...

New York Harbor
New York Harbor is a bay that covers all of the Upper Bay. It is at the mouth of the Hudson River near the East River tidal estuary on the East Coast of the United States. New York Harbor is generally synonymous with Upper New York Bay, which is enclosed by the New York City boroughs of Manhattan, Brooklyn, and Staten Island and the Hudson County, New Jersey, municipalities of Jersey City and Bayonne, although in colloquial usage it can sometimes expand to cover Upper and Lower New York Bay New York Harbor is one of the largest natural harbors in the world. Overview The harbor is fed by the waters of the Hudson River (historically called the North River as it passes Manhattan), as well as the Gowanus Canal. It is connected to Lower New York Bay by the Narrows, to Newark Bay by the Kill Van Kull, and to Long Island Sound by the East River, which, despite its name, is actually a tidal strait. It provides the main passage for the waters of the Hudson River as it em ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
