Iceboat
An iceboat (occasionally spelled ice boat or traditionally called an ice yacht) is a recreational or competition sailing craft supported on metal runners for traveling over ice. One of the runners is steerable. Originally, such craft were boats with a support structure, riding on the runners and steered with a rear blade, as with a conventional rudder. As iceboats evolved, the structure became a frame with a seat or cockpit for the iceboat sailor, resting on runners. Steering was shifted to the front. Because of their low resistance to forward motion over ice, iceboats are capable of speeds exceeding . Because of their speed, iceboats are used both for recreation and for racing. Racing craft typically carry one person. A related activity, land sailing, employs sailing craft similar to iceboats, but riding on wheels instead of runners. History The history of iceboating began in Europe in areas where smooth ice was found in the bays of the Baltic Sea and the canals of the ...

International DN
The International DN is a class of iceboat. The name stands for Detroit News, where the first iceboat of this type was designed and built in the winter of 1936–1937. Archie Arrol was a master craftsman working in the Detroit News hobby shop, and together with iceboaters Joe Lodge and Norman Jarrait designed a racing boat they called the "Blue Streak 60", later to become known as the "DN 60". In 1937 a group of 50 laymen worked with Archie in the hobby shop to produce the first fleet of the new iceboats. These first boats broke during the initial season, and after Jarrait and Lodge modified the design to increase the strength, the group got back together to build a second set of iceboats in 1938. This design, featuring a narrow, single-person cockpit, three steel blades in tricycle A tricycle, sometimes abbreviated to trike, is a human-powered (or gasoline or electric motor powered or assisted, or gravity powered) three-wheeled vehicle. Some tricycles, such as cycle ric ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forces On Sails
Forces on sails result from movement of air that interacts with sails and gives them motive power for sailing craft, including sailing ships, sailboats, windsurfers, ice boats, and sail-powered land vehicles. Similar principles in a rotating frame of reference apply to windmill sails and wind turbine blades, which are also wind-driven. They are differentiated from forces on wings, and propeller blades, the actions of which are not adjusted to the wind. Kites also power certain sailing craft, but do not employ a mast to support the airfoil and are beyond the scope of this article. Forces on sails depend on wind speed and direction and the speed and direction of the craft. The direction that the craft is traveling with respect to the "true wind" (the wind direction and speed over the surface) is called the point of sail. The speed of the craft at a given point of sail contributes to the "apparent wind"—the wind speed and direction as measured on the moving craft. The apparen ...

Point Of Sail
A point of sail is a sailing craft's direction of travel under sail in relation to the true wind direction over the surface. The principal points of sail roughly correspond to 45° segments of a circle, starting with 0° directly into the wind. For many sailing craft 45° on either side of the wind is a ''no-go'' zone, where a sail is unable to mobilize power from the wind. Sailing on a course as close to the wind as possible—approximately 45°—is termed ''beating'', a point of sail when the sails are ''close-hauled''. At 90° off the wind, a craft is on a ''beam reach''. The point of sail between beating and a beam reach is called a ''close reach''. At 135° off the wind, a craft is on a ''broad reach''. At 180° off the wind (sailing in the same direction as the wind), a craft is ''running downwind''. A given point of sail (beating, close reach, beam reach, broad reach, and running downwind) is defined in reference to the true wind—the wind felt by a stationary observe ...

Icicle (yacht)
Icicle is the name of the largest ice yacht ever built. It was built for John Aspinwall Roosevelt for racing on the Hudson River, New York state in 1869. It was long and carried of canvas. The yacht is still, over 140 years later, recognized by the ''Guinness Book of Records'' as a world record. John A. Roosevelt (Franklin Delano Roosevelt's Uncle) was the first Commodore of the Hudson River Ice Yacht Club (1885) at Poughkeepsie, NY. His ice yacht, "Icicle", required a railway flat car to transport. In 1871 "Icicle" beat the "Chicago Express" train on a run between Poughkeepsie and Ossining. Early ice yacht clubs spent most of their time racing trains. As of 2021 a man named David Janzen is building an ice boat that will beat Icicle’s world record by being 22 metres long.

White Bear Lake, Minnesota
White Bear Lake is a city in Ramsey County in the state of Minnesota, United States. A small portion of the city also extends into Washington County. The population was 23,769 at the 2010 census. The city is located on White Bear Lake, one of the largest lakes in the Minneapolis–Saint Paul metropolitan area. Origin of name The city is named after its largest lake, White Bear Lake. American writers have delivered differing versions of the legend that explains the origin of the name. In her book ''Indian Legends of Minnesota'', Mrs. Carl T. Thayer writes that "It is said that a Sioux maiden fell in love with a Chippewa brave. She, the daughter of the Chief, on learning that her father planned war against the Chippewa, ran to her lover and warned him. The brave went alone into the Sioux village to ask for peace and the hand of the maiden. Before the Chief would agree, the Chippewa would have to do a brave deed." "The lovers usually met on Manitou Island. One day, as the bra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Land Sailing
Land sailing, also known as sand yachting, land yachting or dirtboating, is the act of moving across land in a wheeled vehicle powered by wind through the use of a sail. The term comes from analogy with (water) sailing. Historically, land sailing was used as a mode of transportation or recreation. Since the 1950s, it has evolved primarily into a racing sport. Vehicles used in sailing are known as sail wagons, sand yachts, or land yachts. They typically have three (sometimes four) wheels and function much like a sailboat, except that they are operated from a sitting or lying position and steered by pedals or hand levers. Land sailing works best in windy flat areas, and races often happen on beaches, airfields, and dry lake beds in desert regions. Modern land sailors, generally known as "pilots", can go three to four times faster than the wind speed. A gust of wind is considered more beneficial in a land sailing race than a favorable windshift. A similar sport, known as ice yachti ...

Aerodynamics
Aerodynamics, from grc, ἀήρ ''aero'' (air) + grc, δυναμική (dynamics), is the study of the motion of air, particularly when affected by a solid object, such as an airplane wing. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics. The term ''aerodynamics'' is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving Aircraft#Heavier than air – aerodynes, heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer simu ...

The Detroit News
''The Detroit News'' is one of the two major newspapers in the U.S. city of Detroit, Michigan. The paper began in 1873, when it rented space in the rival ''Detroit Free Press'' building. ''The News'' absorbed the '' Detroit Tribune'' on February 1, 1919, the ''Detroit Journal'' on July 21, 1922, and on November 7, 1960, it bought and closed the faltering ''Detroit Times''. However, it retained the ''Times building, which it used as a printing plant until 1975, when a new facility opened in Sterling Heights. The ''Times'' building was demolished in 1978. The street in downtown Detroit where the Times building once stood is still called "Times Square." The Evening News Association, owner of ''The News'', merged with Gannett in 1985. At the time of its acquisition of ''The News'', Gannett also had other Detroit interests, as its outdoor advertising company, which ultimately became Outfront Media through a series of mergers, operated many billboards across Detroit and the surro ...

Pewaukee, Wisconsin
Pewaukee is a city in Waukesha County, Wisconsin. The population was 13,195 at the 2010 census. The Village of Pewaukee, which was incorporated out of the town before it incorporated as a city, is surrounded by the city. The name of the city of Pewaukee comes from that of the name of the village, which is rather unclear in itself. Many names are given as to the etymology of the name. History The city of Pewaukee was incorporated in 1999, from the parts of the former Town of Pewaukee not included in the Village of Pewaukee. The town had been established by an act of the Wisconsin Territorial Legislature approved January 13, 1840, eight years before Wisconsin gained statehood. When voting took place to decide the county seat for Waukesha County, Waukesha beat out Pewaukee by two votes. At the time, Governor Tyler Novak represented Pewaukee in court. The Chicago, Milwaukee, St. Paul and Pacific Railroad (Milwaukee Road) constructed a railroad line through Pewaukee in 1855, ...

Ice Boat Apparent Wind On Different Points Of Sail
Ice is water frozen into a solid state, typically forming at or below temperatures of 0 degrees Celsius or Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color. In the Solar System, ice is abundant and occurs naturally from as close to the Sun as Mercury to as far away as the Oort cloud objects. Beyond the Solar System, it occurs as interstellar ice. It is abundant on Earth's surfaceparticularly in the polar regions and above the snow lineand, as a common form of precipitation and deposition, plays a key role in Earth's water cycle and climate. It falls as snowflakes and hail or occurs as frost, icicles or ice spikes and aggregates from snow as glaciers and ice sheets. Ice exhibits at least eighteen phases ( packing geometries), depending on temperature and pressure. When water is cooled rapidly (quenching), up to three types of amorphous ice can form depending on its his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
