Esquimalt Harbour
Esquimalt Harbour is a natural harbour in Greater Victoria on the southern tip of Vancouver Island in British Columbia, Canada. The entrance to Esquimalt Harbour is from the south off the Strait of Juan de Fuca through a narrow channel known as Royal Roads. Esquimalt Harbour is situtated east of Victoria Harbour, another major harbour in the region. Esquimalt Harbour is home to the Royal Canadian Navy's Maritime Forces Pacific, based at CFB Esquimalt. Esquimalt Harbour is bounded by the municipalities of Colwood to the west, View Royal to the north, and Esquimalt to the east. The entrance is marked by the historic Fisgard Lighthouse on the Harbour's west shore in Colwood. CFB Esquimalt is situtated at the harbour entrance's east shore. History In the summer of 1790 Manuel Quimper, Gonzalo López de Haro, and Juan Carrasco aboard ''Princesa Real'' explored the Strait of Juan de Fuca where they claimed Esquimalt Harbour for Spain, naming it Puerto de Córdova. From 1842 to 190 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kort Nozzle
A ducted propeller, also known as a Kort nozzle, is a marine propeller fitted with a non-rotating nozzle. It is used to improve the efficiency of the propeller and is especially used on heavily loaded propellers or propellers with limited diameter. It was developed first by Luigi Stipa (1931) and later by Ludwig Kort (1934). The Kort nozzle is a shrouded propeller assembly for marine propulsion. The cross-section of the shroud has the form of a foil, and the shroud can offer hydrodynamic advantages over bare propellers, under certain conditions. Advantages are increased efficiency at lower speeds (10 knots), course stability when sailing astern, and increase of cavitation. Ducted propellers are also used to replace rudders. History Luigi Stipa in 1931 and later Ludwig Kort (1934) demonstrated that an increase in propulsive efficiency could be achieved by surrounding the propeller with a foil-shaped shroud in the case of heavily loaded propellers. A "Kort Nozzle" is referre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bollard Pull
Bollard pull is a conventional measure of the pulling (or towing) power of a watercraft. It is defined as the force (in tonnes force, or kilonewtons (kN)) exerted by a vessel under full power, on a shore-mounted bollard through a tow-line, commonly measured in a practical test (but sometimes simulated) under test conditions that include calm water, no tide, level trim, and sufficient depth and side clearance for a free propeller stream. Like the horsepower or mileage rating of a car, it is a convenient but idealized number that must be adjusted for operating conditions that differ from the test. The bollard pull of a vessel may be reported as two numbers, the ''static'' or ''maximum'' bollard pull - the highest force measured - and the ''steady'' or ''continuous'' bollard pull, the average of measurements over an interval of, for example, 10 minutes. An equivalent measurement on land is known as drawbar pull, or tractive force, which is used to measure the total horizontal for ...

Harbour Tug
A tugboat or tug is a marine vessel that manoeuvres other vessels by pushing or pulling them, with direct contact or a tow line. These boats typically tug ships in circumstances where they cannot or should not move under their own power, such as in crowded harbour or narrow canals, or cannot move at all, such as barges, disabled ships, log rafts, or oil platforms. Some are ocean-going, some are icebreakers or salvage tugs. Early models were powered by steam engines, long ago superseded by diesel engines. Many have deluge gun water jets, which help in firefighting, especially in harbours. Types Seagoing Seagoing tugs (deep-sea tugs or ocean tugboats) fall into four basic categories: #The standard seagoing tug with model bow that tows almost exclusively by way of a wire cable. In some rare cases, such as some USN fleet tugs, a synthetic rope hawser may be used for the tow in the belief that the line can be pulled aboard a disabled ship by the crew owing to its lightne ...

Canadian American Strategic Review
The Canadian American Strategic Review was an influential Canadian think-tank that comments on Canadian Defence and sovereignty issues. The think-tank operated, for many years, from the campus of Simon Fraser University. History In 2007 the '' Canwest News Services'' cited one of the think-tank's papers on the option of employing Canadian Forces smaller CH-146 Griffon helicopters to Afghanistan. In 2008 the US Naval War College's '' International Law Studies'' cited one of the think-tank's papers on Canadian Prime Minister Stephen Harper's 2005 change in Defence policy. In 2009 Peter Worthington cited one of the review's papers that statistically analyzed the safety of the vehicles the Canadian Forces used in Afghanistan. In 2016, Steven Chase repeatedly quoted the Review's Stephen Priestley when ''The Globe and Mail'' reported on how Saudi Arabia used Canadian made light armored vehicles in ways that violated their export license. The reporting raised questions about a new Sau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Harbor Vessels Of Canada
A harbor (American English), harbour (British English; see spelling differences), or haven is a sheltered body of water where ships, boats, and barges can be docked. The term ''harbor'' is often used interchangeably with ''port'', which is a man-made facility built for loading and unloading vessels and dropping off and picking up passengers. Ports usually include one or more harbors. Alexandria Port in Egypt is an example of a port with two harbors. Harbors may be natural or artificial. An artificial harbor can have deliberately constructed breakwaters, sea walls, or jettys or they can be constructed by dredging, which requires maintenance by further periodic dredging. An example of an artificial harbor is Long Beach Harbor, California, United States, which was an array of salt marshes and tidal flats too shallow for modern merchant ships before it was first dredged in the early 20th century. In contrast, a natural harbor is surrounded on several sides of land. Examples of n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
