Benjamin Lexcen AM (born Robert Clyde Miller, 19 March 1936 – 1 May 1988) was an Australian yachtsman and marine architect. He is famous for the winged keel design applied to Australia II which, in 1983, became the first non-American yacht to win the prestigious America's Cup in 132 years. Early life Born in the small town of Boggabri, New South Wales on 19 March 1936. After his parents, labourer Edward William Miller and Ethel Doreen, née Green abandoned him as a child he stayed briefly at Boys' Town, Engadine, before going to his grandfather at Newcastle. He left school at age 14 to pursue a locomotive mechanic's apprenticeship but soon found his attention turning to sailboats. At 16, he designed his first sailboat The Comet with his friend William Bennett in Hamilton, NSW, and began to make a name for himself in local competition. Miller did his sailmaking apprenticeship with Norman Wright in Queensland. Miller's designs were highly innovative. His entry, "Taipan" in the 1960 18Footer World Championship started the modern era of the class and Miller won the World Championship in 1961 with the successor, "Venom". With friend Craig Whitworth, he founded a boatbuilding, sail-making and ship-chandlery firm (Miller and Whitworth) and designed boats part-time as well. One of his lasting early successes was the design that became the International Contender. It was selected in 1967, in multi boat trials, as a potential Olympic successor to the Finn dinghy. The Contender was awarded International status in 1968 and now has fleets in more than twelve countries throughout the world. His keelboat designs of the early 1970s featured clean, easily driven hulls and relatively small sail area. He had great success with a series of these designs starting with the innovative "Ginkgo". Miller competed in the 1972 Munich Olympics representing Australia in sailing with Denis O'Neil and Ken Berkeley as fellow crew members. America's Cup Miller was commissioned by Alan Bond to build Apollo, an ocean racer. This partnership continued when Bond first challenged for the America's Cup in 1974 with the Miller-designed 12-metre class yacht Southern Cross, named for the southern hemisphere constellation. Their challenge for the Cup was unsuccessful but Miller was kept on as the designer for future yachts, all of them designed to the 12-metre class rules as used for America's Cup competition at the time. During the first years of his partnership with Bond,
