Welcome to Utopia!
Project Utopia has more in common with an oil rig than it does with a yacht, and in the word's of the consultancy, "breaks the traditional naval architectural mould which the market has come to expect and offers a truly unique outlook free from any conventional design constraints."
...Yacht Island Design's Project Utopia measures some 330 ft (100 m) in length and breadth, spans 11 decks and has the equivalent floorspace of a present-day cruise liner - indeed, and I'm sure this will be a draw-card to any aspiring wealthy megalomaniacs, there is enough space to create an entire micro-nation.
First and foremost, the island's design is stable, being based on a four legged platform and designed for minimum motion in the most extreme sea conditions. Each leg supports a fully azimuthing thruster and with four such units, the design can redeploy between desired locations at slow speed. _Gizmag
