SS Faith
The SS ''Faith'' was the first concrete ship built in the United States. It was constructed by the San Francisco Shipbuilding Company in 1918 owned by William Leslie Comyn. It cost $750,000. The construction Work began September 1, 1917; concrete pouring began October 31, 1917 and ended February 26, 1918. The Steam Ship (SS) Faith launched on March 14, 1918, from Redwood City, California. The ship was designed by Alan Macdonald and Victor Poss. It pulled up to 5000 tons, being the largest concrete ship of its time. The cost of the hull itself was estimated at , and the early estimate before completion was that it would total overall. Dimensions *102,56 x 13,56 x 6,86 metres 336.5 x 44.5 x 22.5 feet *6125 tons *2 triple expansion steam machines *1760 Horsepower *10 knots History ''" ..said William Leslie Comyn ..he likewise pointed out the lack of steel-making plants and shipyards on the West Coast.

William Leslie Comyn
William Leslie Comyn (born 30 October 1877) was a Californian businessman, shipbuilder and builder of one of the first large concrete ships. Life Comyn was the second son of Charles Comyn an English civil servant and was born at Shepherd's Bush, London. His great-uncle Stephen George Comyn had been naval chaplain to the English Admiral Lord Nelson. He was educated at Merchant Taylor's School, and Dulwich College and subsequently founded his own shipping company - Comyn Singleton and Dunn of Gracechurch Street London EC1. Through this business he went to California where he settled and became a businessman in San Francisco. His father in law William Emil Gerber of Sacramento, California was a merchant and financier, and may have supported his enterprises. One of the ships he built was a five master sailing ship named Ann Comyn after his wife. During World War I Leslie Comyn, tried to persuade the United States Shipping Board (USSB) that they should build concrete ships. They were ...

Concrete Ships
Concrete ships are built of steel and ferrocement (reinforced concrete) instead of more traditional materials, such as steel or wood. The advantage of ferrocement construction is that materials are cheap and readily available, while the disadvantages are that construction labor costs are high, as are operating costs. (Ferrocement ships require thick hulls, which results in either a larger cross-sectional area that hurts hydrodynamics, or leaves less space for cargo.) During the late 19th century, there were concrete river barges in Europe, and during both World War I and World War II, steel shortages led the US military to order the construction of small fleets of ocean-going concrete ships, the largest of which was the SS ''Selma''. United States Maritime Administration (MARAD) designation for concrete ships-barges was Type B ship. Few concrete ships were completed in time to see wartime service during World War I, but during 1944 and 1945, concrete ships and barges were used to su ...

Steam Ship
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'' (using a propeller or screw). As paddle steamers became less common, "SS" is 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. As steamships were less dependent on wind patterns, new trade routes opened up. The steamship has been described as a "major driver of the first wave of trade globalization (1870–1913)" and contributor to "an increase in international trade that was unprecedented in human ...

Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the stea ...

Knot (unit)
The knot () is a unit of speed equal to one nautical mile per hour, exactly (approximately or ). The ISO standard symbol for the knot is kn. The same symbol is preferred by the Institute of Electrical and Electronics Engineers (IEEE), while kt is also common, especially in aviation, where it is the form recommended by the International Civil Aviation Organization (ICAO). The knot is a non- SI unit. The knot is used in meteorology, and in maritime and air navigation. A vessel travelling at 1 knot along a meridian travels approximately one minute of geographic latitude in one hour. Definitions ;1 international knot = :1 nautical mile per hour (by definition), : (exactly), : (approximately), : (approximately), : (approximately) : (approximately). The length of the internationally agreed nautical mile is . The US adopted the international definition in 1954, having previously used the US nautical mile (). The UK adopted the international nautical mile definition in 1970, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Breakwater (structure)
A breakwater is a permanent structure constructed at a coastal area to protect against tides, currents, waves, and storm surges. Part of a coastal management system, breakwaters are installed to minimize erosion, and to protect anchorages, helping isolate vessels within them from marine hazards such as prop washes and wind-driven waves. A breakwater, also known in some contexts as a jetty, may be connected to land or freestanding, and may contain a walkway or road for vehicle access. On beaches where longshore drift threatens the erosion of beach material, smaller structures on the beach, usually perpendicular to the water's edge, may be installed. Their action on waves and current is intended to slow the longshore drift and discourage mobilisation of beach material. In this usage they are more usually referred to as groynes. Purposes Breakwaters reduce the intensity of wave action in inshore waters and thereby provide safe harbourage. Breakwaters may also be small structu ...
