Robert Duncan and Co
Robert Duncan and Co of Port Glasgow was a shipbuilder
1830 Robert Duncan left the shipyard of James MacMillan of Greenock at the age of 35 to set up his own company in part of the East Yard, Port Glasgow, obtained from John Wood and Co. He went on to build sailing ships for a number of different owners. Duncan had already spent his working life in the shipbuilding industry, and he brought a wealth of knowledge with him to his own company.
Built the hull of RMS Britannia under subcontract to Robert Napier, which ship opened the North Atlantic mail service for the British and North American Royal Mail Steam Packet Company. Duncan built the hulls for the paddle steamers Clyde and Teviot for the Royal Mail Line as subcontractors to Caird and Co who manufactured the engines.
Duncans also built a ship, the Flambeau, to J. S. Russell's design as a means of checking the efficacy of his wave line theory.
1862 Robert Duncan Junior decided to strike out on his own. With John McGregor and John Hamilton and using his father's company name, he took over the East Yard in Port Glasgow from John Reid and Co. The company was very successful - nearly 400 ships were built in the East Yard from its start until the last was delivered in 1931. He produced many ideas which either were patented or which earned considerable sums of money for himself or associated ship-owners.
1860s The yard mainly built sailing ships for customers all around the world.
