The Aberfoyle

The ship was built by Philip & Son, Kingswear, Dartmouth Harbour, Devon, England, as Yard No.407 for the Lough Swilly Steamboat Company, based in Derry under the management of John McFarland, and initially named The Aberfoyle.^[1] She measured 100 GRT and 58 NRT and was 100.0 ft (30.5 m) in length between perpendiculars, 19.0 ft (5.8 m) in beam, 7.1 ft (2.2 m) in depth,^[1] and a draught of only 4.5 ft (1.4 m).^[2] The Aberfoyle had twin screws, powered by two compound steam engines made by the shipbuilder, totalling 34 nhp or 250 ihp and giving her a service speed of 9 knots (17 km/h); steam was supplied by a single fire-tube boiler operating at 130 psi.^[1][3]

The Aberfoyle arrived in Lough Swilly, County Donegal, via Derry, in October 1912 to enter passenger service between Fahan and Rathmullen.^[3][4] Her licensed capacity was 408 passengers.^[3] She was registered at the Port of Londonderry with British Official Number 121359.^[5]

In October 1920, enroute from Derry to the River Thames the shallow-draught vessel ran into a severe gale in the Irish Sea and, developing engine trouble, was forced to put in to Dublin for repairs.^[2]

Naval service

The vessel was purchased by the Admiralty on 4 November 1920 and her name was shortened to Aberfoyle.^[6] At some point she was attached to submarine depot ship Cyclops.^[7]

In March 1938 the vessel was renamed Dolphin and transferred to be tender to the shore base of that name, the headquarters of the Royal Navy's submarine service, at Gosport in Portsmouth Harbour. The vessel was sold in 1947.^[8]
