Know which ship
to trust. And prove why.
Marigrid gives marine underwriters the two things the job actually demands: a transparent rating to price the risk — VesselScore — and a provenance-stamped dossier to defend the claim — the Evidence Pack.
You can't price what you can't see — and you can't defend a claim you can't evidence.
Sanctions exposure arrives faster than the regulator. Identities change behind a re-flag. When a casualty turns into a dispute, the question is rarely what happened — it's when did you know it. Marigrid is built to answer both, on the record.
A transparent 0–1000 rating any underwriter can read.
Like a credit score is to a lender — an analogy of explainability, not a claim of bureau standing. Components are weighted, every deduction carries a reason code, and a thin file is published Not Rated — never quietly scored clean.
- SN01On an active sanctions list100
- FL01Flag (Cameroon) on the Paris MoU black list75
- ID01Frequent flag changes (flag hopping)35
- BH03Suspected ship-to-ship transfer28
A provenance-stamped dossier. Built for claims, subrogation and screening.
Every score sits on a record of what was known, and when — identity that survives a rename or re-flag, behaviour anchored to the minute, with confidence and sources attached.

Earlier than the regulator. With the confidence interval shown.
Illustrative — representative output, not a live metric. Replaying history point-in-time (with the sanctions hit knocked out so it's prediction, not tautology), VesselScore crosses into High Risk before the designation — and the vessels it would have missed are shown honestly.
One source can be fooled. We cross-validate many.
Fuse
Live ship tracking from multiple AIS networks, layered with sanctions & flag lists, seabed depth and infrastructure geometry — held in one model. Satellite radar on the roadmap.
Reason
A pure detection engine reads behaviour: transponder gaps, ship-to-ship transfer, position spoofing, area jamming, loitering with passive drift removed.
Attribute
Every finding carries its provenance and confidence — which vessel, under what flag, how close, how long — and rolls up into the VesselScore and an exportable Evidence Pack.
The same ledger your underwriters read.
Every score and finding is reason-coded and time-stamped, the way it appears in the Evidence Pack — nothing is computed off the record. This is the live console; the score is just its public face.
