MS Hanseatic
''Heritage Adventurer'' is an ice class, ice-strengthened expedition cruise ship built in 1991 by Rauma shipyard in Finland. She was originally named ''Society Adventurer'', but after Discoverer Reederei was unable to take delivery of the vessel due to financial troubles, the completed ship was laid up at the shipyard for almost two years. In 1993, she was acquired by Hanseatic Tours (which later merged with Hapag-Lloyd) and renamed ''Hanseatic''. In 2018, she was chartered to One Ocean Expeditions and renamed ''RCGS Resolute'' through a partnership with the Royal Canadian Geographical Society. In 2021, she was acquired by Heritage Expeditions and, following an extensive refit, entered service in 2022 with her current name. General characteristics ''Heritage Adventurer'' is length overall, long overall and length between perpendiculars, between perpendiculars, has a beam of and draws of water with a Displacement (ship), displacement of .

Perseverance Harbour
Perseverance Harbour, also known as South harbour, is a large indentation in the coast of Campbell Island / Motu Ihupuku, one of New Zealand's subantarctic New Zealand Outlying Islands, outlying islands. The harbour is a long lateral fissure which reaches the ocean in the island's southeast, and is overlooked by the island's highest point, Mount Honey. The Campbell Island Meteorological Station lies at the western end of the harbour. On 4 November 1810, the island's discoverer, Captain Frederick Hasselborough (or "Hasselburgh" or "Hasselburg"; there are several spellings), who had returned from Sydney, was drowned in Perseverance Harbour, together with Elizabeth Farr, a young woman born at Norfolk Island, and a 12/13 year old Sydney boy, George Allwright.

Controllable Pitch Propeller
Controllability is an important property of a control system and plays a crucial role in many regulation problems, such as the stabilization of unstable systems using feedback, tracking problems, obtaining optimal control strategies, or, simply prescribing an input that has a desired effect on the state. Controllability and observability are dual notions. Controllability pertains to regulating the state by a choice of a suitable input, while observability pertains to being able to know the state by observing the output (assuming that the input is also being observed). Broadly speaking, the concept of controllability relates to the ability to steer a system around in its configuration space using only certain admissible manipulations. The exact definition varies depending on the framework or the type of models dealt with. The following are examples of variants of notions of controllability that have been introduced in the systems and control literature: * State controllability ...

Zodiac Inflatable Boat
Zodiac Nautic, formerly Zodiac Marine & Pool, then Zodiac Marine, is a French company known for their inflatable boats. Originating as an airship company, the boating division was split off from the aerospace-focused Zodiac Group in 2007. In France, "''zodiac''" has become a genericized trademark for an inflatable boat. History Origins, and as part of the Zodiac Group Zodiac originated with the ''Société française de ballons dirigeables et d’aviation Zodiac'' (Zodiac airships and aviation French company), which specialized in the production of airships. In the late 1930s, one of its engineers, Pierre Debroutelle, invented one of the first prototypes of inflatable boats. In 1937, the Aéronavale, the French Naval Air Force, commissioned several boats from Zodiac. The company started marketing to the general public in 1949. Zodiac received publicity in late 1952 after Alain Bombard made a crossing of the Atlantic in a production model of a Zodiac inflatable boat calle ...

Star (classification)
Star ratings are a type of rating scale using a star glyph or similar typographical symbol. It is used by reviewers for ranking things such as films, TV shows, restaurants, and hotels. For example, a system of one to five stars is commonly used in hotel ratings, with five stars being the highest rating. Similar systems have been proposed for electing politicians in the form of score voting and STAR voting. Historical usage Repeated symbols used for a ranking date to Mariana Starke's 1820 guidebook, which used exclamation points to indicate works of art of special value: ...I have endeavored... to furnish Travellers with correct lists of the objects best worth notice...; at the same time marking, with one or more exclamation points (according to their merit), those works which are deemed peculiarly excellent. '' Murray's Handbooks for Travellers'' and then the '' Baedeker Guides'' (starting in 1844) borrowed this system, using stars instead of exclamation points, first ...

Deadweight Tonnage
Deadweight tonnage (also known as deadweight; abbreviated to DWT, D.W.T., d.w.t., or dwt) or tons deadweight (DWT) is a measure of how much weight a ship can carry. It is the sum of the weights of cargo, fuel, fresh water Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salt (chemistry), salts and other total dissolved solids. The term excludes seawater and brackish water, but it does include ..., ballast water, provisions, passengers, and crew. DWT is often used to specify a ship's maximum permissible deadweight (i.e. when it is fully loaded so that its Plimsoll line is at water level), although it may also denote the actual DWT of a ship not loaded to capacity. Definition Deadweight tonnage is a measure of a vessel's weight carrying capacity, not including the empty weight of the ship. It is distinct from the displacement (weight of water displaced), which includes the ship's own weight, or the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Net Tonnage
Net tonnage (NT, N.T. or nt) is a dimensionless index calculated from the total moulded volume of the ship's cargo spaces by using a mathematical formula. Defined in ''The International Convention on Tonnage Measurement of Ships'' that was adopted by the International Maritime Organization in 1969, the net tonnage replaced the earlier net register tonnage (NRT) which denoted the volume of the ship's revenue-earning spaces in "register tons", units of volume equal to . Net tonnage is used to calculate the port duties and should not be taken as less than 30 per cent of the ship's gross tonnage.International Convention on Tonnage Measurement of Ships . International Maritime Organization (IMO). Net tonnage is not a measure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gross Tonnage
Gross tonnage (GT, G.T. or gt) is a nonlinear measure of a ship's overall internal volume. Gross tonnage is different from gross register tonnage. Neither gross tonnage nor gross register tonnage should be confused with measures of mass or weight such as deadweight tonnage or displacement. Gross tonnage, along with net tonnage, was defined by the ''International Convention on Tonnage Measurement of Ships, 1969'', adopted by the International Maritime Organization (IMO) in 1969, and came into force on 18 July 1982. These two measurements replaced gross register tonnage (GRT) and net register tonnage (NRT). Gross tonnage is calculated based on "the moulded volume of all enclosed spaces of the ship" and is used to determine things such as a ship's manning regulations, safety rules, registration fees, and port dues, whereas the older gross register tonnage is a measure of the volume of only certain enclosed spaces.

Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p. 5. This is accomplished by means of its "draft marks". A merchant vessel has t ...

Length Between Perpendiculars
Length between perpendiculars (often abbreviated as p/p, p.p., pp, LPP, LBP or Length BPP) is the length of a ship along the summer load line from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member. When there is no sternpost, the centerline axis of the rudder stock is used as the aft end of the length between perpendiculars. Measuring to the stern post or rudder stock was believed to give a reasonable idea of the ship’s carrying capacity, as it excluded the small, often unusable volume contained in its overhanging ends. On some types of vessels this is, for all practical purposes, a waterline measurement. In a ship with raked stems, naturally that length changes as the draught of the ship changes, therefore it is measured from a defined loaded condition. See also * Length overall Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to ...

Length Overall
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 reported. T ...
