City of Ragusa of Liverpool was a 20-foot (6 m) yawl (in 19th-century terms), owned by Nikola Primorac, which twice crossed the Atlantic in the early days of 19th-century small-boat ocean-adventuring. She carried the former alternative name of Dubrovnik, the birthplace of her owner. She was originally a ship's boat of a merchantman. The 1870 east-west trip between Ireland and the United States was crewed by John Charles Buckley, a middle-aged Irishman with seagoing experience, and Primorac, a Croatian and tobacconist. The crew on the west–east return trip of 1871 were Primorac and a "lad" called Edwin Richard William Hayter from New Zealand, who had been a steward on the steamer City of Limerick of the Inman Line.
