The US Coast Guard this month has requested that Patriots Point Development Authority register the USS Yorktown as a Permanently Moored Vessel. This certification will mean that the Coast Guard would not need to inspect the Yorktown, since it was removed from navigation years ago. Of course, it has been common knowledge that the Yorktown is permanently moored, but the formal paperwork was apparently not completed with the Coast Guard.
Examples of PMVs like the Yorktown include showboats, theaters, hotels, gaming sites, restaurants, museums, and business offices on a barge.
