Sankaty (steamboat)
''Sankaty'' (a.k.a. HMCS ''Sankaty'', a.k.a. ''Charles A. Dunning'') was a propeller-driven steamer that served as a ferry to Martha's Vineyard and Nantucket in Massachusetts; in Rockland, Maine; Stamford, Connecticut and Oyster Bay, Long Island in the United States from 1911 to 1940. During World War II, the ship was requisitioned by the Royal Canadian Navy for service as a minelayer and maintenance vessel along the Canadian Atlantic coast. Following the war the ship returned to a ferry, working the Wood Islands, Prince Edward Island and Caribou, Nova Scotia route in Canada from 1947 until 1964. While being towed to the breaker's yard, the ship sank off the coast of Nova Scotia on October 27, 1964. Description ''Sankaty'' was designed by Chauncey G. Whiton. The ship was long, a slim vessel with twin propellers and twin smokestacks.''The Dukes County Intelligencer''. Vol. 7, No. 4. May 1966 She had a beam, and at the waterline and drew of water.

Oak Bluffs, Massachusetts
Oak Bluffs is a town located on the island of Martha's Vineyard in Dukes County, Massachusetts, United States. The population was 5,341 at the 2020 United States Census. It is one of the island's principal points of arrival for summer tourists, and is noted for its "gingerbread cottages" and other well-preserved mid- to late-nineteenth-century buildings. The town has been a historically important center of African American culture since the eighteenth century. History The first inhabitants of Oak Bluffs were the Wampanoag people, who have lived on Martha's Vineyard (Wampanoag name: Noepe) for approximately 10,000 years. The area that is now Oak Bluffs was called "Ogkeshkuppe," which means "damp/wet thicket or woods." The area was later settled by Europeans in 1642 and was part of Edgartown until 1880, when it was officially incorporated as Cottage City. The town re-incorporated in 1907 as Oak Bluffs, named because the town was the site of an oak grove along the bluffs overlo ...

Royal Canadian Navy
The Royal Canadian Navy (RCN; french: Marine royale canadienne, ''MRC'') is the naval force of Canada. The RCN is one of three environmental commands within the Canadian Armed Forces. As of 2021, the RCN operates 12 frigates, four attack submarines, 12 coastal defence vessels, eight patrol class training vessels, two offshore patrol vessels, and several auxiliary vessels. The RCN consists of 8,570 Regular Force and 4,111 Primary Reserve sailors, supported by 3,800 civilians. Vice-Admiral Angus Topshee is the current commander of the Royal Canadian Navy and chief of the Naval Staff. Founded in 1910 as the Naval Service of Canada (French: ''Service naval du Canada'') and given royal sanction on 29 August 1911, the RCN was amalgamated with the Royal Canadian Air Force and the Canadian Army to form the unified Canadian Armed Forces in 1968, after which it was known as Maritime Command (French: ''Commandement maritime'') until 2011. In 2011, its historical title of "Royal Cana ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water-tube Boiler
A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam. The heated water/steam mixture then rises into the steam drum. Here, saturated steam is drawn off the top of the drum. In some services, the steam passes through tubes in the hot gas path, (a superheater) to become superheated. Superheated steam is defined as steam that is heated above the boiling point at a given pressure. Superheated steam is a dry gas and therefore is typically used to drive turbines, since water droplets can severely damage turbine blades. Saturated water at the bottom of the steam drum returns to the lower dru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triple Expansion Engine
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Although steam-driven devices were known as early as the aeolipile ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vineyard Sound

Hold (ship)
120px, View of the hold of a container ship A ship's hold or cargo hold is a space for carrying cargo in the ship's compartment. Description Cargo in holds may be either packaged in crates, bales, etc., or unpackaged (bulk cargo). Access to holds is by a large hatch at the top. Ships have had holds for centuries; an alternative way to carry cargo is in standardized shipping containers, which may be loaded into appropriate holds or carried on deck. Holds in older ships were below the orlop deck, the lower part of the interior of a ship's hull, especially when considered as storage space, as for cargo. In later merchant vessels it extended up through the decks to the underside of the weather deck. Some ships have built in cranes and can load and unload their own cargo. Other ships must have dock side cranes or gantry cranes to load and unload. Cargo hatch A cargo hatch or deck hatch or hatchway is type of door used on ships and boats to cover the opening to the cargo hold ...

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 extremities of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull Hull may refer to: Structures * Chassis, of an armored fighting vehicle * Fuselage, of an aircraft * Hull (botany), the outer covering of seeds * Hull (watercraft), the body or frame of a ship * Submarine hull Mathematics * Affine hull, in affi ..., 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 fro ...

Funnel (ship)
A funnel is the smokestack or chimney on a ship used to expel boiler steam and smoke or engine exhaust. They are also commonly referred to as stacks. Purpose The primary purpose of a ship's funnel(s) is to lift the exhaust gases clear of the deck, in order not to foul the ship's structure or decks, and to avoid impairing the ability of the crew to carry out their duties. In steam ships the funnels also served to help induce a convection draught through the boilers. Design Since the introduction of steam-power to ships in the 19th century, the funnel has been a distinctive feature of the silhouette of a vessel, and used for recognition purposes. Funnel area The required funnel cross-sectional area is determined by the volume of exhaust gases produced by the propulsion plant. Often this area is too great for a single funnel. Early steam vessels needed multiple funnels ( had 5 when launched), but as efficiency increased new machinery needed fewer funnels. Merchant shi ...

Ship Breaking
Ship-breaking (also known as ship recycling, ship demolition, ship dismantling, or ship cracking) is a type of ship disposal involving the breaking up of ships for either a source of parts, which can be sold for re-use, or for the extraction of raw materials, chiefly scrap. Modern ships have a lifespan of 25 to 30 years before corrosion, metal fatigue and a lack of parts render them uneconomical to operate. Ship-breaking allows the materials from the ship, especially steel, to be recycled and made into new products. This lowers the demand for mined iron ore and reduces energy use in the steelmaking process. Fixtures and other equipment on board the vessels can also be reused. While ship-breaking is sustainable, there are concerns about the use by poorer countries without stringent environmental legislation. It is also labour-intensive, and considered one of the world's most dangerous industries. In 2012, roughly 1,250 ocean ships were broken down, and their average age ...

Caribou, Nova Scotia
Caribou is a small rural community in Pictou County, Nova Scotia, Canada. Located on the Northumberland Strait northwest of the town of Pictou, Caribou is named after the Woodland Caribou which used to live in Nova Scotia. Nearby geographic locations using the name include Caribou Harbour, a bay on which the community is situated, as well as the communities of Caribou Island, Central Caribou and Caribou River. Caribou became an important port after it was selected by the federal government in the late 1930s to be the Nova Scotia terminal for a seasonal ferry service to Wood Islands in eastern Prince Edward Island. The service, operated by Northumberland Ferries Limited since its inception in 1941, carries passenger, vehicle and truck traffic to Wood Islands, Prince Edward Island between May and December. Caribou also hosts a small passenger-only seasonal ferry service to Pictou Island Pictou Island is a Canadian island located in the Northumberland Strait approximately n ...
