Marittima Italiana was an Italian shipping company, established in 1936 as an offshoot of the long-established firm of Lloyd-Triestino, which in the late 1930s operated shipping lines between Italy and east Africa, southern Africa, Asia, and Australia. Shown here is a map of Marittima Italiana’s line from Genoa to Bombay (Mumbai), India. Distances are given for the different sections of the route: from Genoa to Naples, Naples to Port Said, Port Said to Aden, and Aden to Bombay. Inset maps show these five ports and the Suez Canal, with water depths given in meters. Symbols are used to indicate radiotelegraph stations and the availability of coal, fuel oil, and dry-dock facilities at various ports. The clock in the center of the map shows the division of the world into 24 time zones.
