Flag hopping an increasingly popular deceptive shipping tactic among sanctioned fleet
- 36% of the vessels sanctioned in 2025 have already reflagged
- The average time to first flag change post-sanctions has dropped from 85 days to 45 days
- Comoros and Guyana are the most common MMSIs transmitted in AIS data, legitimate or otherwise, outside of those affiliated with the flag registries of sanctioned countries
There have been 215 flag changes recorded already this year, compared to 200 in the whole of 2024
