Other specifications

The Titanic contained two reciprocating four-cylinder, triple-expansion, inverted steam engines, and one low-pressure Parsons turbine. These powered three propellers. There were 25 double-ended and 4 single-ended Scotch-type boilers fired by 159 coal-burning furnaces that made possible a top speed of 23 knots (43 km/h). Only three of the four 63 feet (19 m) tall funnels were functional; the fourth, which served only as a vent, was added to make the ship look more impressive. Titanic could carry a total of 3,547 passengers and crew and, because she carried mail, her name was given the ship prefix Royal Mail Ship (RMS) as well as SS (Steam Ship).

The Titanic was considered a pinnacle of naval architecture and technological achievement, and was thought by The Shipbuilder magazine to be "practically unsinkable."

Titanic had a double-bottom hull, containing 44 tanks for boiler water and ballast to keep the ship safely balanced at sea (later ships also had a double-walled hull). Titanic exceeded the lifeboat standard, with 20 lifeboats (though not enough for all passengers). Titanic was divided into 16 compartments by doors held up, i.e. in the open position, by electro-magnetic latches which could be closed by a switch on the ship's bridge and by a float system installed on the door itself.

The ship was technologically advanced for the period. She had an extensive electrical subsystem with steam-powered generators and ship-wide electrical wiring feeding electric lights. She also boasted two wireless Marconi radio sets manned by operators who worked in shifts, allowing constant radio contact and the transmission of many passenger messages.
