 On the 24th April, Messrs. Harland and Wolff launched a fine steel screw steamer, the Inishowen Head, built for the Ulster Steamship Company, Belfast. The steamer is of the following dimensions : — Length, 340ft.; breadth, 40ft. ; depth 28ft.; about 3100 tons gross register ; built to class 100 Al at Lloyd's, but in scantlings and strengthenings generally is much in excess of their requirements. She has two steel decks, extra outside butt straps on two strakes Of plaiting and bilge strake. All the plating is also increased in thickness throughout above Lloyd's rules. The upper deck is fitted with very substantial iron rails and stanchions. with top- gallant forecastle forward, and a bridge-house 90ft. long amidships extending from side to side of the vessel, forming a complete protection for engine and boiler casings ; iron wheel house and solid bulwarks aft. There are four steam winches, and powerful steam windlass and capstan. also steam steering gear, by Muir and Caldwell, Of Glasgow. The Inishowen Head is built on the cellular double bottom principle, to contain about 700 tons water ballast, with trimming tank aft, fitted for cargo ; is schooner rigged, with two steel pole masts, and will have a total carrying capacity Of about 4700 tons dead weight. Accommodation for captain, officers, and engineers, is amidships, and crew forward. The engines are also by Messrs. Harland and Wolff, of the triple expansion t pc, with all the latest improvements—three cylinders, 24 1/2 by 37 by 64in. diameter, with 48in. stroke, to work at a pressure of 160 lb. The crank and propeller shafting is of Siemens-Martin steel, and the pistons are supplied with MacLaine's patent perfect rings and springs. There are two double ended steel boilers, hydraulic rivetted fitted with Fox's corrugated furnace', and tested to a pressure o 320 lb. to the square inch. The Inishowen Head will be commanded by Captain Thomas M'Calmont, commodore of the line, and is the fifth steamer built by Messrs. Harland and Wolff for the Ulster Company.
