HMS Erin's Isle was originally built as a passenger paddle steamer for the Belfast and County Down Railway (B&CDR) by A&J Inglis of Glasgow, launched in 1912. Designed to serve regional passenger routes, she measured a typical size for a vessel of her type, with a focus on daily commuter and excursion services around Belfast Lough, connecting Belfast with Bangor and Larne. Her construction featured the characteristic paddle wheel propulsion, suitable for short-distance, frequent service, and she was named after Ireland ("Erin" being the Hiberno-English term). Erin's Isle began her service on 12 July 1912, operating seasonally from mid-May to late September each year. Her duties included scheduled runs between Belfast and Bangor, as well as excursions to other destinations in County Down and County Antrim. She proved to be a modern and comfortable vessel for her time, replacing the older PS Slieve Bearnagh. In 1915, her career shifted when the Admiralty inspected her and requisitioned her for military service as an auxiliary minesweeper, renaming her HMS Erin's Isle. During World War I, she served in the Royal Navy, contributing to mine-sweeping operations. After the war, she remained in service until early 1919. On 7 February 1919, while anchored off the Thames Estuary near the Nore sandbank, she was struck and sunk by a drifting mine, resulting in the loss of 23 lives. Only three of her crew survived, and the incident highlighted the dangers faced by naval and auxiliary vessels during post-war mine clearance. The wreck lies in the North Edinburgh Channel off the Thames Estuary. The Admiralty paid substantial compensation for her loss, but economic considerations led the B&CDR to decide against replacing her, marking the end of her maritime service. The wreck remains a site of historical interest, and in the 2000s, the Ministry of Defence assessed it under the Protection of Military Remains Act, although it was not designated as a protected war grave.
