when did the first cruise ship set sail
Cruise ship P&O first introduced passenger cruising services in 1844, advertising sea tours to destinations such as Gibraltar, Malta and Athens, sailing from Southampton. The forerunner of modern cruise holidays, these voyages were the first of their kind, and P&O Cruises has been recognised as the world's oldest cruise line.[6] The company later introduced round trips to destinations such as Alexandria and Constantinople. It underwent a period of rapid expansion in the latter half of the 19th century, commissioning larger and more luxurious ships to serve the steadily expanding market. Notable ships of the era include the SS Ravenna built in 1880, which became the first ship to be built with a total steel superstructure, and the SS Valetta built in 1889, which was the first ship to use electric lights.
