A coverage-weighted blend of the 2 components we could read for this hull — the weights renormalise over only the components present, so a thin read is never inflated and a hull is never credited a “safe 0” for a signal it has no row for. This headline is flagged low-confidence (a thin or structural-only read) and should not be treated as a verdict. Higher means riskier. Derived in-house from government-open port-State-control, flag, sanctions and our own vessel data; weight it by the coverage above.

Design draught looks implausible for this class and size — the figures above are anchored to it, so treat them with extra caution.

Estimate only — modelled from deadweight (deadweight only) using a first-principles hydrostatic model, not measured hydrostatic tables. The design draught it is anchored to is unreliable across the fleet.
