Red zone = Bab el-Mandeb region. Amber = JWC Listed Area. Red dashed = Red Sea zone above JWCLA.
Green = port zones (Djibouti, Berbera, Salalah, Jeddah). Markers coloured by vessel type (use the chips above to filter).
✕ red = spoofed/suspect (reported position).
◇ amber = went dark (last-known position).

Vessels that crossed the Bab el-Mandeb narrows within the selected period (defaults to the latest
pair of snapshots; changes with the From/To range above). “est.” marks crossings inferred across an AIS gap rather than
a clean line-cross. Spoofed positions are excluded.
These positions were detected as GPS-spoofed and excluded from clean data (crossing & dark detection).
Shown here at the reported (false) position so the jamming is visible. Not actual vessel locations.

Last-known position
Vessels whose last AIS fix is 6 h–7 days old (from the dump's "time since last position") and whose
last-known position is within ~250 Nm of the narrows. A "go investigate" triage list — note that genuine transits also go
dark here (AIS coverage is patchy in the strait), so this flags candidates, not confirmed anomalies. Spoofed vessels are
tracked separately.

Dark vessels farther than ~250 Nm from the narrows — lower operational relevance (out in the
wider Red Sea / Arabian Sea), shown for completeness.
