About Capstan Maritime Data

Capstan Maritime Data fuses terrestrial and satellite AIS into clean vessel positions, port calls and voyages for the global merchant fleet. From Singapore it also publishes a weekly container freight rate index and round-the-clock alerts on port congestion and shipping disruptions.

Data sources and methods

Where the data comes from
A terrestrial AIS receiver network, licensed satellite AIS feeds, port authority schedules and notices, vessel registries, and freight quotes submitted by forwarders and shippers.
How it is collected
Real-time AIS ingestion with spoofing and gap detection, berth-level port geofences, analyst-verified event alerts and a weekly anonymous freight rate panel.
What sets it apart
Berth-level polygons for 4,300 ports, AIS spoofing and dark-period flags on every vessel, and a freight index built from submitted all-in quotes rather than published tariffs.

    Freight index is good, lane coverage could be wider

    The weekly index is transparent about its inputs and we now reference it in two contracts. We would like more coverage on intra-Africa and South America east coast lanes, which they say are planned.

    Congestion alerts arrived before our forwarder called

    During a congestion spell at a transhipment hub we had the alert and waiting-time data two days before our forwarder told us. That was enough to rebook two shipments through another port.

    Port call history was exactly what our analysts needed

    We pulled five years of port calls for bulk carriers in Asia and the berth and anchorage times were consistent with the port authority figures we checked. The API is quick and the vessel classification by size saved us a lot of joins.
