Seasteading is the concept of creating permanent dwellings at sea , called seasteads , outside the territories claimed by the governments of any countries , with the goal of the seasteads asserting their own sovereignty . The idea has drawn attention primarily from libertarians . [ 1 ] Most proposed seasteads have been modified cruising vessels. Other proposed structures have included a refitted oil rig, a decommissioned anti-aircraft platform, and custom-built floating islands. [ 2 ] No one has yet succeeded at creating a state on the high seas that has been recognised as a sovereign nation; the closest is perhaps the Principality of Sealand , a disputed micronation formed on a discarded sea fort near Suffolk , England .

The Freedom Ship project is a serious step up from ResidenSea but also unbuilt as of yet, though 1/5 of the on-board living units have already been sold. The concept? A mile-long, energy self-sufficient floating city with absolutely everything included from parks and playgrounds to apartments, businesses, schools, casinos and shopping malls. It will also be fully networked for phone and internet communications. Rather than docking, aircraft will land to resupply the ship and deposit and pick up residents. At 25 stories high the ship would accommodate 40,000 full-time residents and 60,000 total occupants. More than a floating paradise this is designed to be a fully functioning and essentially autonomous city of relatively uniform architecture. Though funding is still needed, signs still point to the eventual completion of this ocean-going wonderland.
