The Star is a one-design racing keelboat for two people designed by Francis Sweisguth in 1910. The Star was the primary Olympic class keelboat from 1932 through 2012 (the last year for the event). It is sloop-rigged, with a mainsail larger in proportional size than any other boat of its length. Unlike most modern racing boats, it does not use a spinnaker when sailing downwind. Instead, when running downwind a whisker pole is used to hold the jib out to windward for correct wind flow. Early Stars were built from wood, but modern boats are generally made of fiberglass. The boat must weigh at least with a maximum total sail area of . The Star class pioneered an unusual circular boom vang track, which allows the vang to effectively hold the boom down even when the boom is turned far outboard on a downwind run. Another notable aspect of Star sailing is the extreme hiking position adopted by the crew and at times the helmsman, who normally use a harness to help hang low off the windward side of the boat with only their lower legs inside. ==History== The Star was designed in 1910 by Francis Sweisguth—draftsman for William Gardner's Naval Architect office—and the first 22 were built in Port Washington, New York by Ike Smith during the winter of 1910–11. Since that time, over 8,400 boats have been built, with more than 2,000 actively racing in 170 fleets. The hull is a hard chine design with a slight curve to the bottom section, and a bulb keel. Stars were originally rigged with a large, low-aspect-ratio gunter mainsail and jib, which was replaced by a short bermuda rig in 1921, before the current tall bermuda sail plan was adopted in 1930. In 1965, fiberglass replaced wood as the primary hull material. Other changes to the strict design rules for the Star class, include adding flexible spars, an innovative circular-track boom vang, and self-bailers.〔 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「Star (keelboat)」の詳細全文を読む スポンサード リンク
