What it does
Vessels is the maritime intelligence domain pack for the SZL Holdings platform. It gives fleet operators, risk managers, and compliance teams a single command surface that correlates AIS telemetry, voyage economics, sanctions exposure, and AI-generated alerts — all governed by the same Proof Chain and Covenant Policy infrastructure that runs every SZL Holdings product.
Every anomaly surfaces a recommended action. Every sanctioned-entity match triggers an approval workflow. Every voyage P&L projection is traceable back to the signal that prompted it.

Note: AIS telemetry is simulated. Live AIS requires a paid provider subscription (~$15–40K/year). See
