What Overwatch doesn't do
  • Live AIS coverage is terrestrial-only today — a handful of tracked ports (including Port Hedland, Tubarão, Dampier, and Hay Point) show no live vessel positions until a satellite or paid AIS feed is wired in.
  • Cargo tonnage is usually computed by interpolating AIS-reported drafts against a hydrostatic table, not full draft-survey hydrostatics — survey-mark metadata is rarely present in production port call records, so the more precise draft-survey method is rarely reached.

Oceanbolt
Self-serve

Oceanbolt tracks dry bulk commodity flows — grain, coal, iron ore, fertilizers — with port-level granularity and an accessible API. It is the most accessible of the specialist platforms, with pricing starting around $500/month and a developer-friendly REST API. The gaps: no oil or LNG coverage, no satellite crop health data, and no vessel risk or sanctions scoring.
