Barclay H. Warburton III

After his resignation, Warburton settled in Newport, Rhode Island. In 1967, he founded the Black Pearl Restaurant, named after his yacht. In 1970 he married Lore M. Faught. In 1972, Warburton sailed to England for the international sail training races from Cowes to Kiel. Afterwards, Warburton set out to create an American sailing organization similar to the international one that organized that race. This led to him and some of his fellow sailing enthusiasts in Newport to found the American Sail Training Association. In 1976 the American Sail Training Association brought 100 Tall Ships to Newport, Philadelphia and Boston to celebrate the American bicentennial.

In 1949, he and his wife, Margaret McKean Read, daughter of Margarett Sargent, moved to Saracen Farm in Ipswich, Massachusetts. From 1953 to 1955 he was a member of the Ipswich Board of Selectmen. In 1954 he was elected to the Massachusetts House of Representatives. He resigned from the House in 1959 amid a public scandal surrounding his marriage.

Warburton graduated from St. Mark's School and the United States Merchant Marine Academy. He served in the United States Navy during World War II and graduated from Harvard University in 1948.

Warburton was born to Barclay Harding Warburton II and Rosamund Lancaster. In 1936 his father died in a hunting accident. His mother later married William Kissam Vanderbilt II. In 1949, Warburton turned over his stepfather's estate, Eagle's Nest, to the public. Eagle's Nest became the Vanderbilt Museum.

Barclay Harding Warburton III (February 5, 1922 – May 1, 1983) was founder of the American Sail Training Association.
