Timothea "Timmy" Larr is a naval architect and three-time winner of United States Women's Sailing Championship.
[1] She described some of the boats she helped design, including a 72-foot double centerboard ketch and a 72 foot catamaran, in a 1966 article in the New York Times that profiled Larr.
As a member of Seawanhaka Corinthian Yacht Club, she sailed her sister's boat to win the Raven national championships in 1961[3] and 1965.
[3][4][15] Sheila McCurdy, the first female Commodore of the Cruising Club of America, describes the summer she spent sailing with Larr in Solings while training to go to the Adams Cup which they won together in 1973.
[17] Larr has written articles and books that train sailors and power boaters,[18][19] worked on the National On-Water Standards for boating safety,[20] and served as chair of the Junior Yacht Racing Association of Long Island Sound (1976-1979).
[21] In 1983, Larr participated in the discussion about winged keels on the America's Cup boats in the 12-Meter Class, thereby bringing her training in naval architecture into the realm of competitive sailing.
