There is a longer history of vessel at http://www.maritimehistoryofthegreatlakes.ca/Documents/Scanner/14/01/default.asp?ID=s00 9 with some additions/corrections in the following issue: http://www.maritimehistoryofthegreatlakes.ca/Documents/Scanner/14/02/default.asp?ID=s00 6 There are a number of stories of her early years on the Lakes at: http://images.maritimehistoryofthegreatlakes.ca/results?dd=1910&q=toiler TYNEMOUNT diesel-electric canaller (British 133544) (signal letters JDPT). Original: 1,644 tons gross, 1,062 tons net. As rebuilt in 1914: 1,744 tons gross, 1,129 tons net, 250' (between perpendiculars), 257' (overall). Her builder was Swan, Hunter and Wigham Richardson of Newcastle England. Yard #922. Hull built by Smith's Dock at Middlesborough England under subcontract. Their Yard #541. Launched 26 Mar 1913, delivered to Swan Hunter on 18 Apr 1913. Machinery probably installed by Swan Hunter. Delivered to owners 17 Sep 1913. Original: Two 300 brake horse power sixcylinder Mirrless, Bickerton & Day diesel engines of a modified land type, each with a 235 KVA generator by Mavor & Coulson and a single electric motor and propeller. As rebuilt by Smith's Dock Yard: Triple expansion 650 indicated horsepower, 80 rated horsepower. Swan Hunter charged Montreal Transportation Co. £24,367 for TYNEMOUNT. The price of the hull, presumably what they paid Smith's Dock, was £13,624. Swan Hunter's profit was said to be £1,447. The Montreal Transportation Co. board had approved construction of an "oil engined screw vessel" for the bulk trades in May 1912. The contract was signed in June. She was to cost £25,600. The contractor was Electric Marine Propulsion Co. Ltd. and the builder was Swan Hunter. It was Ian Buxton, in MarHst-L of 11 and 13 May 2014, who stated that Smith's Dock of Middlesborough were subcontracted to build her hull. It is unclear exactly how much of the original construction work was done by Swan Hunter themselves. Delivery was to be in spring 1913. When built TYNEMOUNT was claimed to be the first large diesel-electric vessel in the world. She was one of four diesel or diesel electric lake vessels built in Britain in the same period, three of which were by Swan Hunter. Her electric generators and motor worked well but the diesels were declared "not suited for marine service". The contract was cancelled by Montreal Transportation Co. in August 1913 due to a failure to meet the delivery date. 83
