'Functionality is never an excuse for poor design' said the naval architect Nicolò Costanzi, a man whose synthesis of engineering and artistry created practical ships of sublime beauty. This book tells the story of the four large passenger ships conceived by Costanzi in the late 1950s and early 1960s. These designs incorporated the most celebrated elements of his work and perhaps reflect the man at the very height of his powers. The 'Costanzi Quartet' comprised Lloyd Triestino's stylish emigrant carriers Galileo Galilei and Guglielmo Marconi, Home Lines' groundbreaking Oceanic and Costa's speed queen, Eugenio C. Profusely illustrated throughout, this book considers their designs and varied careers, as well as offering an insight into life on board through the testimony of passengers and crew. It also sheds light on the man who created them and whose foresight and skill continues to influence contemporary cruise ship design.
