It was difficult, if not almost impossible, to go beyond them without a change to twin screws. If more than the Umbria’s power was to be developed it was safer to use it through two shafts, and the depth of water on the New York bar is a hindrance to the use of a much greater diameter of screw. Mr. Griscom, of Philadelphia, was the bold manager to take the first step by laying down the Inman Company’s ships in 1887, the first of which, the City of New York, was ready for trial in thirteen months after the signing of the contract with Messrs. James & George Thompson, of Clydebank: a wonderful performance. The Teutonic and Majestic quickly after took shape in the yard of Messrs. Harland & Wolff, of Belfast, the place of birth of all of the White Star fleet. These two lines were thus the first to accept the changed conditions, and the City of New York and City of Paris of the former, and the Teutonic and Majestic of the latter, still mark the high-water mark of achievement, both as regards performance as a machine and the comfort and luxury of the passenger. The “Cities,” as they are familiarly termed, are 560 feet in length, by 63 feet broad, displace 13,000 tons, and indicate over 18,000 horse-power. The two White Stars are 582 feet long, by 57 feet 6 inches broad, of 12,000 tons displacement, and of nearly equal horse-power with their two great competitors. In less than twenty years these lines had thus nearly doubled the size of their ships, and more than tripled their power.
