RMS Titanic

RMS 是縮寫, 本意是 Royal Mail Steamer

Royal 即是英國皇家的意思; steamer 是蒸汽推動的船, 在當時是比 輪船 先進的; 由於此船不只載客, 也運送郵件, 故有 mail 一字, 詳情可參考 wikipedia:

Titanic was 882 feet 9 inches (269 m) long and 92 feet 6 inches (28 m) at the beam.[3] She had a Gross Register Tonnage of 46,328 tons, and a height from the water line to the boat deck of 60 feet (18 m).[4] Her three propellers were driven by two four-cylinder, triple-expansion, inverted reciprocating steam engines and one low-pressure Parsons turbine.[5] Steam was provided by 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).[6] Only three of the four 63 foot (19 m) tall funnels were functional; the fourth, which served only as a vent, was added to make the ship look more impressive.[7] Titanic could carry a total of 3,547 passengers and crew and, because she carried mail, her name was given the prefix RMS, (Royal Mail Steamer).
