Freedom Ship was a concept for a floating city proposed by Norman Nixon.

With a design length of 4,500 feet (1400 m), a width of 750 feet (230 m), and a height of 350 feet (110 m), Freedom Ship would be more than 4 times longer than the Queen Mary. The design concepts include a mobile modern city featuring luxurious living, an extensive duty-free international shopping mall, and a full 1.7 million square foot (160,000 m²) floor set aside for various companies to showcase their products. Freedom Ship would not be a cruise ship, it is proposed to be a unique place to live, work, retire, vacation, or visit. The proposed voyage would continuously circle the globe, covering most of the world's coastal regions. Its large fleet of commuter aircraft and hydrofoils would ferry residents and visitors to and from shore.
