Scotian
Allen Line bought the ship on 27 November 1910,[2] renamed her Scotian, and in 1911 registered her in Glasgow. Her UK official number was 129547 and her code letters were HSKG. Allan Line had her refitted with berths for 550 passengers in second class and 1,150 in third class,[3] which changed her tonnages to and. Also by 1911, her navigation equipment included submarine signalling.
In March 1911, Scotian started sailing between Glasgow and Portland, Maine, via Halifax, Nova Scotia. On 6 May 1911 she started her first voyage from Glasgow to Montreal via Quebec. On 18 November 1911 she started her first voyage from Glasgow to Boston, and on 9 May 1912 she started her first voyage from London to Montreal via Quebec.[3]
By 1913 Scotian's wireless telegraph call sign was MJN. In January 1914 Canadian Pacific chartered her for one round trip between Liverpool and Saint John, New Brunswick. On 21 August 1914 she began her final voyage from London to Montreal via Quebec. On her return voyage, she carried part of the Canadian Expeditionary Force to the UK. From November 1914 until March 1915 Scotian was anchored at Ryde, Isle of Wight, as a prison ship for German prisoners of war.[3]
At midnight on 13 September 1916 Scotian was in Glasgow when the armed merchant cruiser HMS Mantua "touched her stem" when being warped across the dock.[4] Neither ship seems to have been damaged.
In 1917 Canadian Pacific took over Allan Line. Allan Line remained Scotian's owner, but CP now managed her. On 4 September 1918 she left Liverpool on her first voyage to New York, and on 3 January 1919 she left Liverpool on her first voyage to Saint John, New Brunswick.[3] CP was the pioneer of a new style of accommodation called cabin class. Later in 1919, CP had Scotian refitted to carry 304 passengers in cabin class and 542 in third class. This changed her tonnages again, to and. On 12 November 1919 she started sailing between Antwerp and Montreal via Southampton and Quebec. On 16 May 1920 she returned to the route between London and Montreal via Quebec. Between 1920 and 1921 the UK Government chartered Marglen for four voyages to Bombay as a troop ship.[3]
