Operation Atlantis was a project, headed by Werner Stiefel, developed with the intent of establishing a libertarian country on international waters. The operation set out to do this by launching a ferro-cement boat into the Hudson River in December 1971 which was piloted into an area near the Bahamas. After reaching its destination it eventually sank in a hurricane.
