Star chart showing area where Muleskinner was space jacked (text upper right)
The USS Muleskinner was a starship, which was spacejacked prior to 2364.
In 2364, the location where the Muleskinner was spacejacked was labeled on a star chart. This chart was stored in the USS Enterprise-D library computer. Later that year, the chart was scanned by Outpost 63. (TNG: "The Naked Now", production art; TNG: "The Last Outpost")
This starship was only mentioned in writing.
The Enterprise computer's star chart was a drawing by Rick Sternbach that had originally been published, years earlier, on page 95 of the reference titled Spaceflight Chronology. This chart showed early commercial lanes and exploration routes, but no text attesting to this fact was included in the portion used on screen, just the labeled names of the ship attack locations. The Muleskinner was a Federation ore freighter attacked and hijacked by Romulans prior to the Earth-Romulan War.
