Maritime Sanctions Data
Ownership opacity across the screened vessel universe
Data as of 2026-06-16 · source: ArcNautical vessel screening (GLEIF ownership chain + jurisdiction tiers over the OFAC-anchored screened set)
Across 1,862 screened vessels, 67.7% have no public GLEIF beneficial-ownership record and 74.4% carry a medium-or-higher ownership-opacity band — data as of 2026-06-16.
| Ownership-opacity band | vessels | % of total | |
|---|---|---|---|
| HIGH | 92 | 4.9% | |
| MEDIUM | 1,294 | 69.5% | |
| LOW | 476 | 25.6% | |
| Total | 1,862 | 100% |
Methodology
- Ownership opacity is the 0–100 score the ArcNautical vessel dossier computes from the GLEIF beneficial-ownership chain and flag jurisdiction, banded LOW (0–30) / MEDIUM (31–60) / HIGH (61–100). Higher is more opaque.
- A vessel with no public GLEIF LEI carries baseline ownership uncertainty — counted as the separate "no public GLEIF record" share.

FAQ
How opaque is the ownership of sanctioned vessels?
As of 2026-06-16, 67.7% of 1,862 screened vessels have no public GLEIF beneficial-ownership record, and 74.4% carry a medium-or-higher ownership-opacity band (LOW 0–30 / MEDIUM 31–60 / HIGH 61–100).
What does ownership opacity measure?
A 0–100 score derived from the vessel's GLEIF ownership chain and flag jurisdiction — registration in a shell-company jurisdiction, an opaque parent chain, or no public beneficial-ownership record all raise it. It is the same score the ArcNautical vessel dossier reports.
