Technical Specifications
Overview
Mega Express Four is a fast roll-on/roll-off ferry owned by Corsica Ferries - Sardinia Ferries and operated on its routes from Italy and France to Corsica and Sardinia. She was built in 1995 by Schichau Seebeckwerft in Bremerhaven, Germany for Superfast Ferries as Superfast II. Between 2003 and 2006 she sailed for Spirit of Tasmania as Spirit of Tasmania III.
Live Tracking
Most time stopped at Rada Di Vado — 4 d across 26 stays.
Derived from the AIS track — runs of near-zero speed (anchored, moored or drifting) snapped to the nearest port. Builds up as we observe the vessel.
Resolved from the live AIS destination. Distance is the real sea route (around land and through canals). The computed ETA is steaming time at the vessel’s passage speed, and does not include any wait for a berth. A destination is the crew’s stated intent, not a confirmed fixture.
Intelligence
Verified reported figure. Band is peer-relative, not official IMO CII.
AIS-derived from our live feed.
Operational Status
Making way at sea speed on its latest broadcast.
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.
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).
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.
Time-in-port summed by port from the AIS-detected port-call history — the ports this vessel has spent the most time at, longest first.
Based on 49 completed calls observed since — open calls (no departure yet) are excluded. The distribution sharpens as AIS history accrues.
Composite Risk
Multiple adverse factors, or a hard ship-specific signal, lift this hull above the fleet norm.
A coverage-weighted blend of the 2 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. This headline is flagged low-confidence (a thin or structural-only read) and should not be treated as a verdict. 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.
