Icebreakers Of The United States Coast Guard
An icebreaker is a special-purpose ship or boat designed to move and navigate through ice-covered waters, and provide safe waterways for other boats and ships. Although the term usually refers to ice-breaking ships, it may also refer to smaller vessels, such as the icebreaking boats that were once used on the canals of the United Kingdom. For a ship to be considered an icebreaker, it requires three traits most normal ships lack: a strengthened hull, an ice-clearing shape, and the power to push through sea ice. Icebreakers clear paths by pushing straight into frozen-over water or pack ice. The bending strength of sea ice is low enough that the ice breaks usually without noticeable change in the vessel's trim. In cases of very thick ice, an icebreaker can drive its bow onto the ice to break it under the weight of the ship. A buildup of broken ice in front of a ship can slow it down much more than the breaking of the ice itself, so icebreakers have a specially designed hull to ...

120106-G-IA651-272 (6668116881)
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flanders
Flanders (, ; Dutch: ''Vlaanderen'' ) is the Flemish-speaking northern portion of Belgium and one of the communities, regions and language areas of Belgium. However, there are several overlapping definitions, including ones related to culture, language, politics, and history, and sometimes involving neighbouring countries. The demonym associated with Flanders is Fleming, while the corresponding adjective is Flemish. The official capital of Flanders is the City of Brussels, although the Brussels-Capital Region that includes it has an independent regional government. The powers of the government of Flanders consist, among others, of economic affairs in the Flemish Region and the community aspects of Flanders life in Brussels, such as Flemish culture and education. Geographically, Flanders is mainly flat, and has a small section of coast on the North Sea. It borders the French department of Nord to the south-west near the coast, the Dutch provinces of Zeeland, North Br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paddle
A paddle is a handheld tool with an elongated handle and a flat, widened distal end (i.e. the ''blade''), used as a lever to apply force onto the bladed end. It most commonly describes a completely handheld tool used to propel a human-powered watercraft by pushing water in a direction opposite to the direction of travel (i.e. paddling). It is different to an oar (which is similar in shape and performs the same function via rowing) in that the latter is attached to the watercraft via a fulcrum. However, the term "paddle" can also be used to describe objects of similar shapes or functions: *A rotating set of paddle boards known as a paddle wheel is used to propel a steamboat (i.e. paddle steamer). *A number of games (e.g. ping-pong), a "paddle" or "bat" is a small racket used to strike a ball. *A mixing paddle is an agitator device used to stir and more thoroughly mix separate ingredients within a mixture. *A spanking paddle is used in corporal punishment, typically to forc ...

Paddler
Canoeing is an activity which involves paddling a canoe with a single-bladed paddle. Common meanings of the term are limited to when the canoeing is the central purpose of the activity. Broader meanings include when it is combined with other activities such as canoe camping, or where canoeing is merely a transportation method used to accomplish other activities. Most present-day canoeing is done as or as a part of a sport or recreational activity. In some parts of Europe canoeing refers to both canoeing and kayaking, with a canoe being called an ''open canoe''. A few of the recreational forms of canoeing are canoe camping and canoe racing. Other forms include a wide range of canoeing on lakes, rivers, oceans, ponds and streams. History of organized recreational canoeing Canoeing is an ancient mode of transportation. Modern recreational canoeing was established in the late 19th century. In 1924, canoeing associations from Austria, Germany, Denmark and Sweden founded the ''Int ...

Kayaks
A kayak is a small, narrow watercraft which is typically propelled by means of a double-bladed paddle. The word kayak originates from the Greenlandic word '' qajaq'' (). The traditional kayak has a covered deck and one or more cockpits, each seating one paddler. The cockpit is sometimes covered by a spray deck that prevents the entry of water from waves or spray, differentiating the craft from a canoe. The spray deck makes it possible for suitably skilled kayakers to roll the kayak: that is, to capsize and right it without it filling with water or ejecting the paddler. ] Some modern boats vary considerably from a traditional design but still claim the title "kayak", for instance in eliminating the cockpit by seating the paddler on top of the boat ("sit-on-top" kayaks); having inflated air chambers surrounding the boat; replacing the single hull with twin hulls; and replacing paddles with other human-powered propulsion methods, such as foot-powered rotational propellers and ...

Arctic
The Arctic ( or ) is a polar region located at the northernmost part of Earth. The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Canada (Yukon, Northwest Territories, Nunavut), Danish Realm (Greenland), Finland, Iceland, Norway, Russia ( Murmansk, Siberia, Nenets Okrug, Novaya Zemlya), Sweden and the United States (Alaska). Land within the Arctic region has seasonally varying snow and ice cover, with predominantly treeless permafrost (permanently frozen underground ice) containing tundra. Arctic seas contain seasonal sea ice in many places. The Arctic region is a unique area among Earth's ecosystems. The cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. Life in the Arctic includes zooplankton and phytoplankton, fish and marine mammals, birds, land animals, plants and human societies. Arctic land is bordered by the subarctic. Definition and etymology The word Arctic comes from the Greek word ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterline
The waterline is the line where the hull of a ship meets the surface of the water. Specifically, it is also the name of a special marking, also known as an international load line, Plimsoll line and water line (positioned amidships), that indicates the draft of the ship and the legal limit to which a ship may be loaded for specific water types and temperatures in order to safely maintain buoyancy, particularly with regard to the hazard of waves that may arise. Varying water temperatures will affect a ship's draft, because warm water is less dense than cold water, providing less buoyancy. In the same way, fresh water is less dense than salinated or seawater with a similar lessening effect upon buoyancy. For vessels with displacement hulls, the hull speed is defined by, among other things, the waterline length. In a sailing boat, the waterline length can change significantly as the boat heels, and can dynamically affect the speed of the boat. A waterline can also refer to ...

Hulst
Hulst () is a municipality and city in southwestern Netherlands in the east of Zeelandic Flanders. History Hulst received city rights in the 12th century. Hulst was captured from the Spanish in 1591 by Maurice of Orange but was recaptured by Archduke Albert in 1596. In 1640, the Dutch forces tried to conquer the city, but they were defeated in battle by the Spanish Army, and Frederick Henry was forced to retreat. In 1645, the Siege of Hulst (to control the left bank of the Schelde river) occurred. It was led by Prince of Orange Frederick Henry, during the Eighty Years' War (1568–1648) with Spain. A further siege took place in 1702, where General Menno van Coehoorn defended the town successfully for the Dutch and in 1747 when it was taken by the French after incompetent defence by Lt. General Pieter de la Rocque. In the seventeenth century, a star fort was constructed. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
