Jim Doty was an American open water swimmer and race director. He served on the International Marathon Swimming Hall of Fame Board of Directors until his passing in 2012 and was inducted as an Honor Swimmer of the IMSHOF in the Class of 2007.

In 1956, Jim finished 78th in the Boston Marathon and decided that longer was better. He had been spending his summers on Black Cat Island, Lake Winniepasaukee, New Hampshire. One time he had to swim a half mile for help after his boat broke down. That swim coupled with his recent 26-mile marathon run and a liking for long distances, led Jim to start swimming long distances in 1968, training with Jack Starrett, a 1964 English Channel Swimmer. Jim trained for a couple of summers with Hall of Fame coach Charlie Silvia at Pine Knoll Swim School in Massachusetts. 

It didn’t take long for Jim to become a local open-water swimming legend; there isn’t a body of water in New England that Jim didn't swim over the course of his lengthy career. In addition to completing a staggering number of marathon swims over several decades, Jim was also dedicated to offering more swimming opportunities to others. To further this mission, he formed the New England Marathon Swimming Association (NEMSA), a non-profit organization dedicated to promoting swimming and a clean environment in New England waters. (NEMSA has since become the New England Open Water Swimming Association, which continues to offer open water opportunities throughout New England). Jim also re-started the Boston Light swim in 1976 after it was halted in 1941 due to World War II. He won the 1976 race with 6 swimmers. In total, Jim swam the Boston Light Swim 18 times and participated as part of 5 relay swims.

He established the International Swimming Hall of Fame Irving Davids/Captain Roger W. Wheeler Memorial Award in 1968 and was also a future recipient of the award.

Jim is the namesake for “The Doty Swim,” an annual, informal, one-mile swim held in memory of James Doty each June at the L Street Bathhouse. There are two Jim Doty Memorial Clocks posted at the clock tower at the L Street Bathhouse in South Boston that aim to help open water swimmers training in the harbor know how long they have been out in the water.

If you want to know more about Jim, there’s a book about his swims, “The Jim Doty Story: Accounts of Some of the Marathon Swims of a Great Boston Swimmer,” by Robert L. McCormack. Jim stated on the dedication page of McCormack’s book: “I want to thank my family: my wife, Paula, and children Polly, Elinor, and Jay. They did not see much of me on the weekends from May to October for many years. Unfortunately, this is one of the sacrifices one makes in the pursuit of a career in ocean and marathon swimming.”
