"The Raby Castle, a single-screw motor ship, which was built to the order of the Lancashire Shipping Co - J. Chambers and Co., Liverpool- by the Caledon Shipbuilding and Engineering Co, of Dundee, and which is engined with an eight-cylinder North-Eastern Werkspoor motor, is a vessel of more than usual interest. She is not large, for her gross tonnage is about 4900 tons, with an overall length of 412ft. 9in., a breadth of 52ft. 3in., and a depth of 37ft., but her machinery is notable on account of the new design of column construction and the fact that the engine is the largest of the type yet installed in a single-screw ship.
The main motor is designed for a normal output of 2200 brake horse-power or 3000 indicated horse-power, at a speed of 92 revolutions per minute. The eight cylinders each have a bore of 28iin. and a stroke of 4ft. 33 3/16in. All auxiliaries are electrically driven with the exception of a small steam boiler, which will be used for emergency starting only. The ship underwent successful trials off the Tyne on Tuesday and Wednesday last, and will take up her work- which eventually will be between New York and the Far East-early next week. In a subsequent issue we hope to give some further particulars of the vessel and of her propelling and auxiliary machinery. "
