Operation Atlantis was a project started by Werner Stiefel in 1968 aiming to establish a new, libertarian nation in international waters. The operation launched a ferro-cement boat on the Hudson River in December 1971 and piloted it to an area near the Bahamas. Upon reaching its destination, it sank in a hurricane. After a number of subsequent failed attempts to construct a habitable sea platform and achieve sovereign status, the project was abandoned.
