The James Postlethwaite was a schooner launched on 11 August 1881 by William Ashburner and Son at Barrow. She was constructed as a tramp coaster, sharing identical plans with the ME Johnson, and was the second-last schooner built by Ashburner’s yard before Ashburner’s death shortly after her launch. The vessel measured approximately in size typical of schooners of her era, designed primarily for trading along the British and Irish east coast, as well as French and Belgian channel ports, without venturing further afield. Initially owned by Thomas Ashburner & Co., Captain Robert Roskell served as her first master. She operated successfully until 1909, when the Ashburner fleet was sold at auction; Captain Ned Hall acquired her for £995. Under his command, she frequently visited continental ports, notably Hamburg, where she was present on the day Britain entered World War I. Subsequently, she was seized by German authorities, her crew imprisoned, and her masts cut down, converting her into a barge used for carrying munitions on the Elbe River. During the war internment, she was held at Hamburg and later in Ruhleben camp near Berlin, where conditions were congested and harsh but where prisoners organized cultural activities, including Irish plays. After the war, she was returned to Captain Hall, refitted, and resumed trading, including routes between Shields and St. Valery. In 1926, she was fitted with an auxiliary engine, although increasingly obsolete compared to motor vessels, which led to her relegation to smaller ports and less profitable cargoes. On 11 May 1929, she was rammed and sunk in Carlingford Lough by the steam collier JJ Monks but was salvaged and repaired. Her later years saw her struggle against the rise of motor ships and economic decline, especially during the Anglo-Irish Trade War. During World War II, she played a vital role in Irish trade, supplying Irish agricultural products to Britain and bringing coal to Ireland, vital for a neutral Ireland with a diminished merchant fleet. Her final notable role was in the 1952 film adaptation of Moby Dick, where she was outfitted as a whaler. After sustaining irreparable damage in a gale at Youghal in 1954, she was beached and eventually burned in 1957. Her wheel remains as a relic displayed at the Moby Dick Inn, marking her long and varied maritime career.
