1842 Advertisement: 'FIRST IRON STEAM-BOAT BUILT IN IRELAND. The chairman of the Board of Works, Sir John Burgoyne, and Colonel Jones, Commissioner of the Shannon Navigation ; J. P. Rhodes, Esq., civil engineer, with a number of scientific gentlemen and others connected with the trade and shipping of the port of Dublin, were invited on Monday to see the first iron steam-boat that has been attempted to be built in Ireland, and which is now on the stocks at the Ringsend Iron Works. The vessel is intended, when the Shannon Navigation is complete, to ply on the Shannon between Athlone and Portumna, and is expected to accomplish the journey, back and forward within each day. The length of her deck is 130 feet; the length of her beam 17 feet 6 inches; depth of hold at shaft 8 feet 6 inches; breadth over all 37 feet. She will be worked by two engines of forty horse power each, and her cabins will be fitted up with every regard to the comfort and convenience of the passengers. After the vessel had been thoroughly inspected both as to its interior and exterior, the visitors were politely invited to partake of a dejeuner, hospitably prepared by Messrs. James and H. Perry and F. Barrington, the highly respectable proprietors of the Ringsend Iron Works.' 
1846 'LAUNCH OF AN IRON STEAM-SHIP. The launch of the iron steam-ship Shamrock took place on Thursday morning, at eleven o'clock, from Mr. Frederick Barrington's Iron Works, Ringsend, Dublin. This beautiful vessel, intended for the London and Dublin trade, was built for the British and Irish Steam Packet Company. She is to be impelled on the new principle, by an engine of thirty-horse power working a screw in her stern. The Shamrock measures on the keel 125, in the beam 21, and her depth of hold is 13 feet. Her tonnage by measurement is about 270; her capacity for cargo is estimated at about 400 tons. She has been about six months in hands; and if we consider that she is the first vessel of her class ever constructed in Dublin, it must be admitted that this time is extremely short. In her construction every modern improvement has been introduced which could add to her strength or safety. The Shamrock has been removed to the Ringsend Floating Dork, where she will take in her engines, also manufactured in the same establishment. She will be also rigged here and completed for sea.' 
1850 'Application of the Screw Propeller to Inland Navigation.—On Saturday last there was launched from the ironworks of Mr. Frederick Barrington, at Ringsend, a large iron canal boat, sixty feet long by twelve feet beam, and six feet depth of hold, the first of a number which it is understood the directors of the Grand Canal Company propose to have built for the carrying trade of that navigation, and which will be propelled by the screw worked by adequate steam power. The machinery for this purpose, and which will be introduced into the boat now launched, has been manufactured by Mr. J. Inshaw, of Birmingham, an ingenious mechanical engineer, who has devoted much time and attention to the subject. The boat, with the machinery complete, is expected to be ready for work upon the Grand Canal in two or three weeks. A second boat, of similar dimensions, and which will in like manner be worked by the screw propeller, has, we are informed, been built for the Canal Company, in London, under the direction of Mr. John Scott Russell, by the well-known firm of Robinsons and Russell in which he partner. The boat is expected shortly to arrive Dublin, and to be also immediately placed on the canal for the carrying trade of the company. Considerable interest is felt by parties connected with the canal and by many scientific persons the results of the experiment so made the directors of the company, and which will be now speedily ascertained.—Saunders News Letter.' .
