With one foot firmly planted in the world of traditional shanties, the veteran sailor and author Stan Hugill also became a leader (and follower) of trends in the folk music revival. His presence as an exclusive performer of sailor songs did much to establish sea music as a revival genre apart from or within folk music. By the late 1970s, the activities of enthusiasts and scholar-performers at places like the Mystic Seaport Museum (who initiated an annual Sea Music Festival in 1979) and the San Francisco Maritime Museum established sea music—inclusive of shanties, sea songs, and other maritime music—as a genre with its own circuit of festivals, record labels, performance protocol, and so on.
