What is "seasteading"

n. The creation of permanent dwellings at sea, outside the territory claimed by any national government.

Seasteading is the concept of creating permanent dwellings at sea, called seasteads, outside the territory claimed by any government. Most proposed seasteads have been modified cruising vessels. Other proposed structures have included a refitted oil platform, a decommissioned anti-aircraft platform, and custom-built floating islands.

No one has created a state on the high seas that has been recognized as a sovereign state. The Principality of Sealand is a disputed micronation formed on a discarded sea fort near Suffolk, England. The closest things to a seastead that have been built so far are large ocean-going ships sometimes called " floating cities", and smaller floating islands.

The term combines the words sea and homesteading. At least two people independently began using it: Ken Neumeyer in his book Sailing the Farm (1981) and Wayne Gramlich in his article "Seasteading – Homesteading on the High Seas" (1998).
