The British Peer was a 1428-ton three-masted iron sailing ship built for the British Shipowners Company at the Harland and Wolff yards in Belfast, Ireland, in 1865. She was 247.5 feet (75.4 m) long, 36.4 feet (11.1 m) wide and 22.5 feet (6.9 m) deep. She was bought by the Nourse Line in 1883, and was the fastest vessel in their fleet until the British Ambassador was commissioned. In 1878, however, British Peer‍ '​s sailing power was compromised, when alterations were made to increase her tonnage by lengthening her hull by 32 feet (9.8 m), and she was never as fast again.
