*Bump*
Could someone with access to various online databases (e.g. Miramar, Fairplay archives) check what information, if any, they have about the Lister? It seems unlikely that there's no trace of her anywhere since the Gibraltar incident.
Equasis says her DNV class was withdrawn (survey overdue) and I also found her from the Internet Archive snapshot of the classification society's class suspension/withdrawal list. According to ShipSpotting she has dual class (DNV and BV), but she's not in the VeriSTAR database.
