# GUR Shadow Fleet — Masters

One row per ship master (captain) GUR names in connection with a shadow-fleet vessel (534 individuals), with name, date of birth, tax id (TIN), citizenship and the vessel they command (name, GUR id, IMO). This is personal data published by GUR — handle it accordingly. Non-spatial plain Parquet; join to **vessels** on `vessel_imo` / `vessel_gur_id`.
