HMCS Grizzly (Z14)
HMCS ''Grizzly'' was an armed yacht acquired by the Royal Canadian Navy during World War II for coastal patrol and anti-submarine defence. Constructed in 1909 as ''Machigonne'', a yacht for William L. Douglas, the vessel was purchased by the United States Navy in 1917 for use as a patrol ship on the United States East Coast during World War I and named USS ''Machigonne'' (SP-507). Following the end of the war, ''Machigonne'' was demobilised and returned to service as a yacht. At the onset of World War II, the Royal Canadian Navy sought capable vessels for port defence, and finding few in Canadian hands, went south to American ports and purchased suitable ships there. ''Machigonne'' was discovered and acquired. However, a lack of familiarity with ''Machigonne''s propulsion system led to it being burnt out before entering service. Though commissioned as HMCS ''Grizzly'', the armed yacht was not given the modifications that other Canadian armed yachts were and spent the majo ...

Guard Ship
A guard ship is a warship assigned as a stationary guard in a port or harbour, as opposed to a coastal patrol boat, which serves its protective role at sea. Royal Navy In the Royal Navy of the eighteenth century, peacetime guard ships were usually third-rate or fourth-rate ships of the line. The larger ships in the fleet would be laid up "in ordinary" with skeleton crews, the spars, sails and rigging removed and the decks covered by canvas – the historic equivalent of a reserve fleet. By contrast the guard ships would carry sails and rigging aboard, be defouled below the waterline to increase their speed under sail, and be manned by at least one quarter of their normal crew. A port or major waterway may be assigned a single guardship which would also serve as the naval headquarters for the area. Multiple guardships were required at larger ports and Royal Dockyards, with the largest single vessel routinely serving as the Port Admiral's flagship. If war was declared, or an en ...

Governor Of Massachusetts
The governor of the Commonwealth of Massachusetts is the chief executive officer of the government of Massachusetts. The governor is the head of the state cabinet and the commander-in-chief of the commonwealth's military forces. Massachusetts has a republican system of government that is akin to a presidential system. The governor acts as the head of government while having a distinct role from that of the legislative branch. The governor has far-reaching political obligations, including ceremonial and political duties. The governor also signs bills into law and has veto power. The governor is a member of the Massachusetts Governor's Council, a popularly elected council with eight members who provide advice and consent on certain legal matters and appointments. Beginning with the Massachusetts Bay Company in 1629, the role of the governor has changed throughout its history in terms of powers and selection. The modern form of the position was created in the 1780 Constitution o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

William L
William is a male given name of Germanic origin.Hanks, Hardcastle and Hodges, ''Oxford Dictionary of First Names'', Oxford University Press, 2nd edition, , p. 276. It became very popular in the English language after the Norman conquest of England in 1066,All Things William"Meaning & Origin of the Name"/ref> and remained so throughout the Middle Ages and into the modern era. It is sometimes abbreviated "Wm." Shortened familiar versions in English include Will, Wills, Willy, Willie, Bill, and Billy. A common Irish form is Liam. Scottish diminutives include Wull, Willie or Wullie (as in Oor Wullie or the play ''Douglas''). Female forms are Willa, Willemina, Wilma and Wilhelmina. Etymology William is related to the given name ''Wilhelm'' (cf. Proto-Germanic ᚹᛁᛚᛃᚨᚺᛖᛚᛗᚨᛉ, ''*Wiljahelmaz'' > German ''Wilhelm'' and Old Norse ᚢᛁᛚᛋᛅᚼᛅᛚᛘᛅᛋ, ''Vilhjálmr'').

Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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" (or "load lines"). A mer ...

Vertical Triple Expansion
A compound steam engine unit is a type of steam engine where steam is expanded in two or more stages. A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure ''(HP)'' cylinder, then having given up heat and losing pressure, it exhausts directly into one or more larger-volume low-pressure ''(LP)'' cylinders. Multiple-expansion engines employ additional cylinders, of progressively lower pressure, to extract further energy from the steam. Invented in 1781, this technique was first employed on a Cornish beam engine in 1804. Around 1850, compound engines were first introduced into Lancashire textile mills. Compound systems There are many compound systems and configurations, but there are two basic types, according to how HP and LP piston strokes are phased and hence whether the HP exhaust is able to pass directly from HP to LP ( Woolf compounds) or whether pressure fluctuation necessitates an intermediate "buffer" space in the form of a s ...

Draft (hull)
The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, 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 from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a cor ...
