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.
- 3 export formats
- MP4 video, Rhino .3dm, CSV.
- 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.
1. Decode the black box
Raw VDR & AIS resolve into one scrubbable picture. Tracks, headings and true-scale hulls, cleanly interpolated.
2. Replay
The scene plays with the bridge's VHF in your ears. Audio anchored where it was heard, your notes and the ship's alarms on the same clock. Clips carry into the video export.

3. Measure risk, not guesses
Select any two vessels: Stingray draws the chord at their closest moment, beside the CPA/TCPA the bridge's radar had predicted. Exact separation, exact second.

4. Analyse the manoeuvre
Rudder, engine and heading as charts. Hover a peak to light up the moment it happened on the map.

Leave with the artifacts. An MP4 fly-through, a Rhino .3dm scene, and CSV tables. The same picture, in the format the next desk needs.

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.

Parsed in browser memory. Never uploaded, and not retained after parse.
Exports
- MP4

- CSV
Generated entirely on your machine, saved through the file picker.

- cloud · EU
Your choice: a local .stingray file that never leaves your machine, or encrypted cloud save for cross-device work.
