Though sister ships and modeled on similar lines, the _Mauretania_ and
_Lusitania_ differ somewhat in construction. Of the two the _Mauretania_
is the more typical ship as well as the more popular. This modern
triumph of the naval architect and marine engineer was built by the firm
of Swan, Hunter & Co. at Wellsend on the Tyne in 1907. The following are
her dimensions: Length over all 790 feet. Length between perpendiculars
760 feet. Breadth 88 feet. Depth, moulded 60.5 feet. Gross tonnage
32,000. Draught 33.5 feet. Displacement 38,000 tons.

She has accommodation space for 563 first cabin, 500 second cabin, and
1,300 third class passengers. She carries a crew of 390 engineers, 70
sailors, 350 stewards, a couple of score of stewardesses, 50 cooks,
the officers and captain, besides a maritime band, a dozen or so
telephone and wireless telegraph operators, editor and printers for
the wireless bulletin published on board and two attendants for the
elevator.

The type of engine is what is known as the Parsons Turbine. There are
23 double ended and 2 single ended boilers. The engines develop 68,000
horse power; they are fed by 192 furnaces; the heating surface is
159,000 square feet; the grate surface is 4,060 square feet; the steam
pressure is 195 lbs. to the square inch.

The highest speed attained has been almost 26 knots or 30 miles an
hour. At this rate the number of revolutions is 180 to the minute. The
coal daily consumed by the fiery maw of the furnaces is enormous. On
one trip between Liverpool and New York more than 7,000 tons is required
which is a consumption of over 1,500 tons daily.
