SS Andrea Doria
SS ''Andrea Doria'' , was an ocean liner for the Italian Line (Società di navigazione Italia) home-ported in Genoa, Italy, known for its sinking in 1956, where of the 1,706 passengers and crew, 1,660 were rescued, while 46 passengers and crew died. Named after the 16th-century Genoese admiral Andrea Doria, the ship had a gross register tonnage of 29,100 and a capacity of about 1,200 passengers and 500 crew. Of all Italy's ships at the time, ''Andrea Doria'' was the largest, fastest and supposedly safest. Launched on 16 June 1951, the ship began her maiden voyage on 14 January 1953. On 25 July 1956, while ''Andrea Doria'' was approaching the coast of Nantucket, Massachusetts, United States, bound for New York City, the eastbound of the Swedish American Line collided with her. Struck in the side, the top-heavy ''Andrea Doria'' immediately started to list severely to starboard, which left half of her lifeboats unusable. The consequent shortage of lifeboats could have result ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ocean Liner
An ocean liner is a passenger ship primarily used as a form of transportation across seas or oceans. Ocean liners may also carry cargo or mail, and may sometimes be used for other purposes (such as for pleasure cruises or as hospital ships). Cargo vessels running to a schedule are sometimes called ''liners''. The category does not include ferry, ferries or other vessels engaged in short-sea trading, nor dedicated cruise ships where the voyage itself, and not transportation, is the primary purpose of the trip. Nor does it include tramp steamers, even those equipped to handle limited numbers of passengers. Some shipping companies refer to themselves as "lines" and their container ships, which often operate over set routes according to established schedules, as "liners". Ocean liners are usually strongly built with a high Freeboard (nautical), freeboard to withstand rough seas and adverse conditions encountered in the open ocean. Additionally, they are often designed with thicker H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nantucket
Nantucket () is an island about south from Cape Cod. Together with the small islands of Tuckernuck and Muskeget, it constitutes the Town and County of Nantucket, a combined county/town government that is part of the U.S. state of Massachusetts. It is the only such consolidated town-county in Massachusetts. As of the 2020 census, the population was 14,255, making it the least populated county in Massachusetts. Part of the town is designated the Nantucket CDP, or census-designated place. The region of Surfside on Nantucket is the southernmost settlement in Massachusetts. The name "Nantucket" is adapted from similar Algonquian names for the island, but is very similar to the endonym of the native Nehantucket tribe that occupied the region at the time of European settlement. Nantucket is a tourist destination and summer colony. Due to tourists and seasonal residents, the population of the island increases to at least 50,000 during the summer months. The average sale price f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ocean Surface Wave
In fluid dynamics, a wind wave, water wave, or wind-generated water wave, is a surface wave that occurs on the free surface of bodies of water as a result from the wind blowing over the water surface. The contact distance in the direction of the wind is known as the ''fetch''. Waves in the oceans can travel thousands of kilometers before reaching land. Wind waves on Earth range in size from small ripples, to waves over high, being limited by wind speed, duration, fetch, and water depth. When directly generated and affected by local wind, a wind wave system is called a wind sea. Wind waves will travel in a great circle route after being generated – curving slightly left in the southern hemisphere and slightly right in the northern hemisphere. After moving out of the area of fetch, wind waves are called '' swells'' and can travel thousands of kilometers. A noteworthy example of this is waves generated south of Tasmania during heavy winds that will travel across the Pacif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
