This paper presents a new concept for the cruise ship, which has been developed from our thesis work. 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. If a 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.
