Crew ETA

not reported

Resolved from the live AIS destination. Distance is the real sea route (around land and through canals). “Off the port” is steaming time only; “likely alongside” adds the wait this port has actually kept comparable ships for. The queue is a typical case, not a promise — berth waits vary far more than they average. A destination is the crew’s stated intent, not a confirmed fixture.

Hull age

Read from the single most-recent AIS broadcast we hold for this hull — we keep no position history, so this is a point-in-time posture, not a dwell inference. Derived in-house from our own AIS feed; weight it by the broadcast age above.

Port calls

4 recent · AIS-detected

Arrivals, time in port and the load/discharge inferred from the draught change — detected from AIS track history. An open call means the vessel is still in port (no departure observed yet).

Haifa Israel Shipyards Port

Haifa Israel Shipyards Port

→ · 18 h in port· draught 4.1→4.1 m

Method: each call is a run of fixes inside a port’s geofence confirmed by a stop (or an AIS gap); load/discharge is the sign of the draught delta over the call. Indicative — arrivals before our AIS history began read from the first observation.

Hull age56

Flag register100

A coverage-weighted blend of the 3 components we could read for this hull — the weights renormalise over only the components present, so a thin read is never inflated and a hull is never credited a “safe 0” for a signal it has no row for. Higher means riskier. Derived in-house from government-open port-State-control, flag, sanctions and our own vessel data; weight it by the coverage above.
