In 1972 Alan Fogarty of Tamar Marine Services won the contract to build the tug Yorktown, for the port of Launceston Authority. This brought a considerable amount of work into the Glasgow Engineering workshop. The machining of propeller shafts, boring stern tubes, manufacturing the white metal stern bearings, machining rudder stocks and bearings and the machining of the rudder palm was all carried out by Glasgow Engineering personnel. All this work was done to the Lloyds survey specifications and passed by their representative. The launching of this vessel was very spectacular, as it was side launched into the North Esk.
