Overview
Stena Britannica, launched in 2009, is the second of two identical Ropax cruiseferries built by Wadan Yards in Warnemünde and nearby Wismar, Germany for Stena Line. The first of the two ships, launched in January 2010, was Stena Hollandica. Both ships operate across the southern North Sea between Harwich in Essex, England, and Hook of Holland, Netherlands, providing a twice daily service. The ships were specifically designed for this route.
Live Tracking
Most time stopped at Rotterdam Europoort — 9 d across 43 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.
Intelligence
Verified reported figure. Band is peer-relative, not official IMO CII.
AIS-derived from our live feed.
Operational Status
Stopped, anchored or moored on its latest broadcast — parked, not necessarily withdrawn.
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 103 completed calls observed since — open calls (no departure yet) are excluded. The distribution sharpens as AIS history accrues.
Composite Risk
Some elevated factors — typically age or a lower-graded flag — but no acute ship-specific flag.
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.
