An ice boat (often spelled as "iceboat") is a boat or purpose-built framework similar in functional design to a sail boat but fitted with skis or runners (skates) and designed to run over ice instead of through (liquid) water. Ice yachting is the sport of sailing and racing iceboats. Sail-able ice is known in the sport as "hard water" versus sailing on liquid or "soft" water. A related sport, land sailing, utilizes a configuration with an iceboat-like fuselage or frame equipped with wheels instead of runners. Iceboats commonly used for racing are usually only for one person, but several classes of two-seat and multiple-seat iceboats are more or less common. On some boats, a "side car" can be fitted to take others along for a ride. ==History== Traditional iceboats from before the late 19th century were used for transportation of goods and racing. These boats reached lengths of 30 to and were sometimes transported between sites on rail cars. Ice sailing was first developed in Europe. In America, it was done in several locations where the sport also continues today. Many active ice sailing clubs are thriving in the northern States and Canadian Provinces, including on the Hudson River; Long Island Sound; Detroit, Michigan; Sandusky, Ohio; Gull Lake, Michigan; Lake Muskegon, Michigan; Geneva Lake, Wisconsin; Oshkosh, Wisconsin; Hamilton Bay, Ontario, Rondeau Bay, Ontario; Ghost Lake, Alberta and on other venues as far south as Decatur and Springfield, Illinois. Some of the older large "stern steerer" iceboats can seat several in their "baskets." Several of these boats are maintained and raced today. The Northwest Ice Yacht Association sponsors an annual regatta that includes classes for these boats. This annual regatta recently celebrated its 100th anniversary. One unique type of ice boat has its history in wide, stubby, scow-like vessels used in the 1800s, often for transportation across a mixed passage transitioning over sea-ice and open water. Wildly sailed by adjusting main and jib sail trim only, these boats had no rudder. Parallel rails were mounted on the bottom, like multiple sled runners. These early vessels (called an "ice scooter" or "bay scooter") were capable of simultaneously and daringly traversing both open water and jumping onto stretches of ice and were used primarily for winter transportation to and from lighthouses and for ice fishing. In 1869, one of the largest ice yachts ever was built for racing on the frozen Hudson River, called the ''Icicle''. That boat occasionally raced the railroad which ran alongside the Hudson. The first iceboats were adaptations of regular sailing boats, with a wooden plank fastened cross-wise at the front having a fixed runner at each end, and a steering runner attached to the bottom of the rudder at the stern (back). These early ice sailing vessels led to the development of boats designed strictly for racing on ice. These "stern-steerer" iceboats were generally rigged as sloops, with a jib sail forward of the mast, although the catboat style with a single sail was also used. The traditional stern-steerer boats were largely replaced by front steering boats in the 1930s, following the development of this style by Walter Beauvois of Williams Bay, Wisconsin in a boat named the ''Beau Skeeter''. This boat led to the "Skeeter" class, and the ''Skeeter Ice Boat Club'' formed on Geneva Lake, Wisconsin. The Skeeter class adopted the logo of a mosquito on their sail, and has evolved into a very efficient aerodynamically clean machine. While the large stern-steerers could have up to of sail, the Skeeter class is limited to just of sail. In 1937, The Detroit News sponsored a new home-buildable ice boat design, which became the International DN. In 1968 Dick Slates of Pewaukee, Wisconsin designed and built the ''Nite'' with two wooden prototypes. The design was refined and fiberglass production began in 1970. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ice boat」の詳細全文を読む スポンサード リンク
