Flag States & Registries

Know how your flag behaves at sea.

A registry answers for its fleet’s conduct and usually learns of an incident after the phone rings. Traffik measures the flagged fleet continuously: where it operates, which official lists name it, and how its movements sit against published speed, habitat and structure rules.

The flagged fleet, measured

See the whole flag, not just the paperwork.

The register records what a yacht is. Traffik records what she does: live positions, seasonal patterns and the jurisdictions where a flagged fleet actually spends its year, drawn from a worldwide archive of measured yacht movement.

List watch

A list naming your flag, known the day it appears.

The Paris MoU current detention list, OFAC SDN and UK Sanctions List vessel entries are scanned daily and matched against the flagged fleet three ways: IMO number, current name, and prior identity from the rename record. The registry hears it from its own watch, not from the press.

What the record shows
Port-state detentionsA flagged hull on the current list is a same-day alert, with her live position and recent movement attached.
Sanctions designationsVessel entries are diffed on every run; a new designation naming a flagged hull alerts the day it is published.
Prior identitiesEntries filed under a former name still match, so a renamed hull never slips past the watch.

Conduct screening

See how the fleet behaves in regulated waters.

Measured positions are screened daily against published speed zones, sanctuary and habitat rules, protected-seagrass extents and charted structures, and each signal is attributed to the vessel’s flag. A registry sees its fleet’s pattern before a coastal state or an insurer presents it.

Every signal is screening-grade, carries its evidence and method, and is never a finding of breach. Repeat signals by the same hull are flagged distinctly.

FAQ

Questions from Flag States and Registries

How does Traffik identify the yachts flying a flag?

By the registry identity itself: MMSI country prefixes, IMO numbers and registered names, reconciled against the rename record so a hull keeps its history through an identity change. Coverage is stated per vessel; a tracked fleet is not the whole register.

Can Traffik alert us when a flagged yacht is detained or designated?

Yes. The Paris MoU current detention list, OFAC SDN and UK Sanctions List vessel entries are scanned daily and matched to the flag by IMO, current name and prior identity. A hit produces a same-day alert with the hull’s recent movement attached.

Can Traffik show how our fleet behaves in protected waters?

Traffik screens measured positions against published speed zones, sanctuary rules, protected-seagrass areas and charted structures, and attributes each screening signal to the vessel’s flag. Every flag is a screening signal with its evidence attached, never a finding of breach.

Do you monitor AIS transmission gaps?

Extended silences are recorded as review items with the last observed position and the duration of the gap. Silence alone does not establish a carriage violation; it identifies where a registry may want to ask the question.

Can Traffik support a casualty investigation?

The measured record supports movement reconstruction around a reported incident: the vessel’s approach, speed, nearby traffic and conditions, delivered as a reviewed report. Every client-facing report carries a named human review before release.

Is this surveillance of owners?

No. Traffik measures the market, not the person. Registry access is scoped to vessels flying the flag, built from broadcast and published records, and named-vessel detail follows Traffik’s access rules based on the client’s relationship to the hull.
