Iceboating
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 N ...

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 ...

Sloop
A sloop is a sailboat with a single mast typically having only one headsail in front of the mast and one mainsail aft of (behind) the mast. Such an arrangement is called a fore-and-aft rig, and can be rigged as a Bermuda rig with triangular sails fore and aft, or as a gaff-rig with triangular foresail(s) and a gaff rigged mainsail. Sailboats can be classified according to type of rig, and so a sailboat may be a sloop, catboat, cutter, ketch, yawl, or schooner. A sloop usually has only one headsail, although an exception is the Friendship sloop, which is usually gaff-rigged with a bowsprit and multiple headsails. If the vessel has two or more headsails, the term cutter may be used, especially if the mast is stepped further towards the back of the boat. When going before the wind, a sloop may carry a square-rigged topsail which will be hung from a topsail yard and be supported from below by a crossjack. This sail often has a large hollow foot, and this foot is sometimes fil ...

Downwind
Windward () and leeward () are terms used to describe the direction of the wind. Windward is ''upwind'' from the point of reference, i.e. towards the direction from which the wind is coming; leeward is ''downwind'' from the point of reference, i.e. along the direction towards which the wind is going. The side of a ship that is towards the leeward is its "lee side". If the vessel is heeling under the pressure of crosswind, the lee side will be the "lower side". During the Age of Sail, the term ''weather'' was used as a synonym for ''windward'' in some contexts, as in the ''weather gage''. Because it captures rain, the windward side of a mountain tends to be wet compared to the leeward it blocks. Origin The term "lee" comes from the middle-low German word // meaning "where the sea is not exposed to the wind" or "mild". The terms Luv and Lee (engl. Windward and Leeward) have been in use since the 17th century. Usage Windward and leeward directions (and the points o ...

Apparent Wind
Apparent wind is the wind experienced by a moving object. Definition of apparent wind The ''apparent wind'' is the wind experienced by an observer in motion and is the relative velocity of the wind in relation to the observer. The ''velocity of the apparent wind'' is the vector sum of the ''velocity of the headwind'' (which is the velocity a moving object would experience in still air) plus the ''velocity of the true wind''. The headwind is the additive inverse of the object's velocity; therefore, the ''velocity of the apparent wind'' can also be defined as a vector sum of the ''velocity of the true wind'' minus the ''velocity of the object''. Apparent wind in sailing In sailing, ''apparent wind'' is the speed and direction of wind indicated by a wind instrument (anemometer) on a ''moving'' craft (on water, land or ice) in undisturbed air. It is composed of the ''combined'' speeds and directions of the craft and wind observed by a ''stationary'' wind instrument—the ''true w ...

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 ...

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 ...

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, ...

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 ...

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 ...
