Why vessel and port data drives real decisions
Ocean visibility is a genuine commercial need. Knowing where a vessel is, when it will berth and how congested a port has become drives real decisions in supply chain planning, commodity trading and freight procurement. The demand is not in question.
AIS is broadcast openly by ships, and VesselFinder turns it into pages any visitor can read: positions, movements, port calls and vessel particulars. Collected on a schedule, those pages answer the questions above across a fleet or a port rather than one ship at a time.
So we collect what the site shows and use it for what it supports: fleet composition, port association, movement observation and per vessel position over time, keyed on vessel identifiers, with provenance recorded per row.
The second reason is port congestion. Arrivals, waiting time at anchorage and berth turnaround, tracked per port over time, are a leading indicator for schedule reliability on the lanes that call there.
The third is continuity. We build, run and repair the collector as the site changes, so the feed keeps arriving.
