Endeavour II (barque)
''Endeavour II'' was a three-masted auxiliary barque built in Vancouver in 1968 and originally named ''Monte Cristo''. She was built along the lines of the brigantine ''Albatross'' as published in Uffa Fox's ''Second Book of Boats''. In late February 1971 she was embayed during a full gale and, after attempting to beat her way out for several days, on 22 February was driven onto the bar of Parengarenga Harbour, a few miles south of North Cape, New Zealand, and wrecked. Construction Her hull was constructed of mahogany planking on heavy fir frames with spars of Sitka spruce. Her three-sectioned mainmast rose from deck to truck. Her deck measured which bowsprit and jibboom extended to almost length overall. She was rigged as a three-masted barque with square sails on the mainmast and foremast, a gaff rigged fore and aft spanker on the mizzenmast, four jibs and a variety of staysails for a maximum of seventeen sails set totalling . The sails were controlled by around of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Length Overall
__NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. LOD Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often repor ...

Gaff Rigged
Gaff rig is a sailing rig (configuration of sails, mast and stays) in which the sail is four-cornered, fore-and-aft rigged, controlled at its peak and, usually, its entire head by a spar (pole) called the ''gaff''. Because of the size and shape of the sail, a gaff rig will have running backstays rather than permanent backstays. The gaff enables a fore and aft sail to be four sided, rather than triangular. A gaff rig typically carries 25 percent more sail than an equivalent Bermudian rig for a given hull design. A sail hoisted from a gaff is called a gaff-rigged (or, less commonly, gaff rigged or gaffrigged) sail. Description Gaff rig remains the most popular fore-aft rig for schooner and barquentine mainsails and other course sails, and spanker sails on a square rigged vessel are always gaff rigged. On other rigs, particularly the sloop, ketch and yawl, gaff rigged sails were once common but have now been largely replaced by the Bermuda rig sail, which, in addition t ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Occupation Of Alcatraz
The Occupation of Alcatraz (November 20, 1969 – June 11, 1971) was a 19-month long protest when 89 Native Americans and their supporters occupied Alcatraz Island. The protest was led by Richard Oakes, LaNada Means, and others, while John Trudell served as spokesman. The group lived on the island together until the protest was forcibly ended by the U.S. government. The protest group chose the name Indians of All Tribes (IOAT) for themselves. IOAT claimed that, under the Treaty of Fort Laramie between the U.S. and the Lakota tribe, all retired, abandoned, or out-of-use federal land was to be returned to the Indians who once occupied it. As Alcatraz penitentiary had been closed on March 21, 1963, and the island had been declared surplus federal property in 1964, a number of Red Power activists felt that the island qualified for a reclamation by Indians. The Occupation of Alcatraz had a brief effect on federal Indian Termination policies and established a precedent for India ...

Port Townsend, Washington
Port Townsend is a city on the Quimper Peninsula in Jefferson County, Washington, United States. The population was 10,148 at the 2020 United States Census. It is the county seat and only incorporated city of Jefferson County. In addition to its natural scenery at the northeast tip of the Olympic Peninsula, the city is known for the many Victorian buildings remaining from its late 19th-century heyday, numerous annual cultural events, and as a maritime center for independent boatbuilders and related industries and crafts. The Port Townsend Historic District is a U.S. National Historic Landmark District. It is also significantly drier than the surrounding region due to being in the rainshadow of the Olympic Mountains, receiving only of rain per year. History The bay was originally named "Port Townshend" by Captain George Vancouver in 1792, for his friend the Marquis of Townshend. It was immediately recognized as a good safe harbor, although strong south winds and poor holdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marine VHF Radio
Marine VHF radio is a worldwide system of two way radio transceivers on ships and watercraft used for bidirectional voice communication from ship-to-ship, ship-to-shore (for example with harbormasters), and in certain circumstances ship-to-aircraft. It uses FM channels in the very high frequency (VHF) radio band in the frequency range between 156 and 174 MHz, inclusive, designated by the International Telecommunication Union as the ''VHF maritime mobile band''. In some countries additional channels are used, such as the L and F channels for leisure and fishing vessels in the Nordic countries (at 155.5–155.825 MHz). Transmitter power is limited to 25 watts, giving them a range of about . Marine VHF radio equipment is installed on all large ships and most seagoing small craft. It is also used, with slightly different regulation, on rivers and lakes. It is used for a wide variety of purposes, including marine navigation and traffic control, summoning rescue servic ...

Block And Tackle
A block and tackle or only tackle is a system of two or more pulleys with a rope or cable threaded between them, usually used to lift heavy loads. The pulleys are assembled to form blocks and then blocks are paired so that one is fixed and one moves with the load. The rope is threaded through the pulleys to provide mechanical advantage that amplifies the force applied to the rope. Hero of Alexandria described cranes formed from assemblies of pulleys in the first century. Illustrated versions of Hero's ''Mechanica'' (a book on raising heavy weights) show early block and tackle systems. Overview A block is a set of pulleys or sheaves mounted on a single frame. An assembly of blocks with a rope threaded through the pulleys is called tackle. The process of threading ropes or cables through blocks is called "reeving", and a threaded block and tackle is said to have been "rove". A block and tackle system amplifies the tension force in the rope to lift heavy loads. They are common ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winches
A winch is a mechanical device that is used to pull in (wind up) or let out (wind out) or otherwise adjust the tension of a rope or wire rope (also called "cable" or "wire cable"). In its simplest form, it consists of a spool (or drum) attached to a hand crank. Traditionally, winches on ships accumulated wire or rope on the drum; those that do not accumulate, and instead pass on the wire/rope (see yacht photo above), are called capstans. Despite this, sailboat capstans are most often referred to as winches. Winches are the basis of such machines as tow trucks, steam shovels and elevators. More complex designs have gear assemblies and can be powered by electric, hydraulic, pneumatic or internal combustion drives. It might include a solenoid brake and/or a mechanical brake or ratchet and pawl which prevents it unwinding unless the pawl is retracted. The rope may be stored on the winch. When trimming a line on a sailboat, the crew member turns the winch handle with one hand, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galvanised
Galvanization or galvanizing ( also spelled galvanisation or galvanising) is the process of applying a protective zinc coating to steel or iron, to prevent rusting. The most common method is hot-dip galvanizing, in which the parts are submerged in a bath of hot, molten zinc. Protective action The zinc coating, when intact, prevents corrosive substances from reaching the underlying iron. Additional electroplating such as a chromate conversion coating may be applied to provide further surface passivation to the substrate material. History and etymology The earliest known example of galvanized iron was encountered by Europeans on 17th-century Indian armour in the Royal Armouries Museum collection. The term "galvanized" continues to be used metaphorically of any stimulus which results in activity by a person or group of people. In modern usage, the term "galvanizing" has largely come to be associated with zinc coatings, to the exclusion of other metals. Galvanic paint, a prec ...

Manila Rope
Manila rope is a type of rope made from manila hemp. Manila hemp is a type of fiber obtained from the leaves of the abacá Abacá ( ; fil, Abaka ), binomial name ''Musa textilis'', is a species of banana native to the Philippines, grown as a commercial crop in the Philippines, Ecuador, and Costa Rica. The plant, also known as Manila hemp, has great economic impo .... It is not actually hemp, but named so because hemp was long a major source of fiber, and other fibers were sometimes named after it. The name refers to the Manila, capital of the Philippines, one of the main producers of abacá. Applications and properties Manila rope is very durable, flexible, and resistant to Seawater, salt water damage, allowing its use in rope, hawsers, ships' lines, and fishing nets."abaca" ''Encyclopædia Britannica''. 22 January 2007.

Standing Rigging
Standing rigging comprises the fixed lines, wires, or rods, which support each mast or bowsprit on a sailing vessel and reinforce those spars against wind loads transferred from the sails. This term is used in contrast to running rigging, which represents the moveable elements of rigging which adjust the position and shape of the sails. Historical development Early sailing vessels used rope of hemp or other fibers, which gave way to wire ropes of various types. Galvanized steel was common for the first half of the 20th century, continuing as an inexpensive option to its 1960s successor material—stainless steel cables and rods. In the late 20th Century, racing yachts adopted composite fiber lines for standing rigging, with the goal of reducing weight and windage aloft. Materials On modern yachts, standing rigging is often stainless steel wire, Nitronic-50 stainless steel rod or synthetic fiber. Semi-rigid stainless steel wire is by far the most common as it combines extre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Running Rigging
Running rigging is the rigging of a sailing vessel that is used for raising, lowering, shaping and controlling the sails on a sailing vessel—as opposed to the standing rigging, which supports the mast and bowsprit. Running rigging varies between vessels that are rigged fore and aft and those that are square-rigged. History of materials In centuries past, a ship's rigging was typically fashioned from rope. In the 19th century this was commonly referred to as Manilla, a reference to the origin of much good quality rope. Traditionally the running rigging was easily recognized since, for flexibility, it was not coated with tar and therefore of a lighter color than the standing rigging which was tarred for protection from weather and therefore darker or even black in color. On modern vessels, running rigging is likely to be made from synthetic fibers, while the standing rigging is most often fashioned from stainless steel "wire rope". Since the 1990s, several new synthetic fibe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
