Reconstruct the incident. Frame by frame

Stingray decodes AIS & VDR recordings into one interactive reconstruction. Built to be examined, measured and defended. In your browser, in minutes. For investigators, experts and claims teams.

0 guesses
Stingray decodes from published standards and the ship’s own records. It never reverse-engineers a format.
7 ingest formats
6 NMEA dialects (VDR included) and CSV.
5 export formats
MP4 video, Rhino .3dm, CSV, PNG, SVG.
100% in browser
Zero install. No data has to leave your machine.

Every layer of the
incident, reconstructed

Decode the black box, show the data that matters, and measure exactly how close they came.

Raw VDR & AIS resolve into one scrubbable picture. Tracks, headings and true-scale hulls, cleanly interpolated.

One reconstruction.
Four ways to see it

Radar view

What the bridge could see. A radar PPI centred on any vessel, with range rings, trails and vectors. Exports as PNG.

The Stingray radar view: a dark PPI scope centred on one vessel, with range rings, a bearing scale and a data column.

Map workspace

What actually happened. Every vessel on the chart, with tracks, live data cards and closest approach.

The Stingray map workspace: two vessel hulls converging in a harbour, their tracks drawn on a dark chart.

Quadrant view

The data beside the motion. The map and three synced charts in one 2×2 frame, exported as a single MP4.

The Stingray quadrant view: a 2×2 grid with the map top-left and three synced time-series charts.

Chart Studio

What goes in the report. Compose and annotate chart exhibits, then export them as SVG or PNG.

Stingray’s Chart Studio: a two-panel speed and course figure beside a source inspector and export controls.

Built for forensic work.

Every detail an investigator needs to inspect, measure and stand behind what happened on the water.

Casework stays
on your machine.

Stingray parses recordings in your browser, on your hardware. The source file is never uploaded, never retained, never visible to us. Exports render locally and save where you choose.

  • NMEA
  • CSV
  • VDR

Parsed in browser memory. Never uploaded, and not retained after parse.

Exports

  • MP4

Federico Dagnino

Built by the people who do the work.

Stingray is co-founded by Federico Dagnino, a practicing forensic naval analyst, and the engineer who builds it. Every feature is built for live casework, then generalised. The tool this work needed didn’t exist, so they built it.
