Why ArcNautical

Published methodology. Defensible numbers.

Most maritime intel platforms are closed black boxes. ArcNautical publishes every signal, every weight, every data source. If your team can’t defend the number to a regulator, it’s noise — not intelligence.

10 signals, one score

Every voyage risk score fuses ten independent intelligence signals through weighted, active-signal scoring. Zero-count signals are excluded automatically—only real threats drive the composite.

VoyageRiskScore

Quantified port-to-port risk assessment fusing ten independent intelligence sources into a single 0–100 score. Full driver breakdown shows exactly what's driving the risk.

  • 10 weighted signal sources with active-signal redistribution
  • CII safety floors prevent under-scoring war zones
  • Data confidence indicator with missing source warnings
  • Sub-2s scoring across 510+ port pairs

Stochastic Monte Carlo

500 weather-coupled simulations per voyage. AR(1) correlated weather sequences produce realistic ETA distributions, not just point estimates.

  • Beaufort speed curves per vessel type & load condition
  • Per-segment weather from Open-Meteo marine API
  • P10–P90 ETA distribution with median highlight
  • Container, bulk, tanker, LNG, general cargo models

Fleet & Dark Activity

Real-time vessel tracking with automatic dark activity detection. AIS gaps, speed anomalies, and unauthorized zone entries trigger instant alerts.

  • AIS gap detection with configurable thresholds
  • Dead reckoning position estimation during gaps
  • Geofence zones with entry/exit monitoring
  • Fleet-wide risk dashboard with KPI metrics

Container Tracking

Track containers across 21 major carriers by BOL, container number, or booking reference. Every tracked shipment is cross-referenced against live threat intelligence—so you don't just see where your cargo is, you see what risks surround it.

  • Track by BOL, container number, or booking reference
  • 21 carriers: Maersk, MSC, CMA CGM, Hapag-Lloyd, ONE, and more
  • Full milestone timeline: loaded, departed, transshipped, arrived, delivered
  • Cross-referenced with voyage risk scores and threat intelligence
