摘要：This paper presents a new concept for the cruise ship, which has been developed from a thesis work discussed at the master＇s degree in Yacht and Cruise Vessel Design, at La Spezia, Italy. A typical cruise ship docked at port does not interact with the city, but remains a guest in transit. Why not then take on the challenge of designing a functional entity that transports events, culture and entertainment？ The ship would then become an extension of the city, offering a different experience each time to suit the tastes of all the family. Ira ship can be ＂inhabited＂, a city can be ＂inhabited on the water＂. The ship does not have a particularly residential facade but it has a multifunctional body.
