Maritime Chokepoint Transit Attribution

Tracking predicted, confirmed, and dark vessel passages through strategic maritime straits and canals.

Maritime chokepoint transit attribution tracks commercial vessel passages across narrow strategic waterways — including the Panama Canal, Suez Canal, Strait of Hormuz, Bab el-Mandeb, Malacca Strait, and Turkish Straits — where canal draft restrictions, queue backlogs, or regional security diversions directly alter delivered commodity supply and voyage ton-miles. Overwatch classifies candidate passages across predicted, confirmed, dark-transit, missed, and cancelled states, pairing arrival-time uncertainty windows with post-transit confirmation timestamps and weekly median ETA deltas. Distinguishing confirmed transits from dark transits gives physical traders and risk analysts explicit provenance when vessels reroute around a cape or traverse a corridor with interrupted AIS broadcasts.
