Every vessel ≥ 100 GT carries a unique seven-digit IMO number assigned for life — it stays with the hull through ownership and name changes. The current set indexed here is curated (famous ULCVs, ULCCs, cruise flagships, historic vessels, plus representative bulkers, tankers, gas carriers, ro-ros and offshore units).
1000 vessels indexed. Track any vessel by IMO on MarineTraffic, VesselFinder, or Equasis.
