DESIGN AND CONSTRUCTION OF PASSENGER STEAMERS. 



said elsewhere, this branch of passenger-ship design is most fascinating ; full plans, however, 

 involve an amount of work beyond the scope of this paper, and it is hoped that these few 

 remarks will be of interest as well as of some value. It is submitted that a full design 

 along the lines of recent experience in battle cruiser and air craft carrier practice is worth 

 while. 



As regards weights,, it is clear that warship practice rather than merchant would have to 

 be followed for machinery design ; the absence of armor, torpedo protection ; battery and am- 

 munition weights being utilized on deck erections, passenger accommodations and bunkers.

It must be remembered that some of the British battle cruisers during the war made suc- 

 cessful passages of the Northern Atlantic at a very high rate of speed. Particulars of these 

 voyages, made during the war, are not generally known, but it is safe to say that valuable 

 information was obtained thereby. 



THE BEGINNINGS OF OUR POSTWAR PASSENGER FLEET. 



During the war our dependence on allied transports for the army troop movements was 

 only mitigated by our few prewar troopers and liners and by enemy tonnage seized in our 

 harbors and elsewhere. This led to the ordering of some twenty odd large and some thirty 

 odd moderate sized transports at Newport News, Bethlehem, New York Shipbuilding Cor- 

 poration and Hog Island. None of these vessels were completed prior to the armistice, and 

 some were subsequently cancelled, mainly the smaller ones at Hog Island. These ships are 

 now in service, some as troopers (Hog Island) and some as passenger liners, with the 

 latter of which only are we here concerned. 



A brief description of these passenger ships is in order and may well be given in tabular 

 form. Of the larger ships, Newport News built two, Bethlehemi five, and New York Ship- 

 building Corporation nine, a total of sixteen ships of some 225,600 gross tons; the smaller 

 ships number seven, all built by the New York Shipbuilding Corporation, totaling some 73,800 

 tons gross.
