In mid-1875 a new ship started construction in London, England. The vessel was the SS Duckenfield and the shipbuilder was J. & W. Dudgeon. The new ship was 49.1 metres long and 7.3 metres wide with a displacement of 368 tons gross. She was powered by a two cylinder vertical steam engine (also built by J. & W. Dudgeon ) turning a single prop. Late that year, the Duckenfield left London for Newcastle where she was due to join the fleet of J. & A. Brown. As well as delivering the ship, cargo was being carried, namely 31 wagons and 40 sets of wheels for the Minmi colliery in the Hunter Valley (interestingly, a ship called the SS Minmi was later to be wrecked off the Southern Sydney coast ).
