Technical Specifications
Overview
MS Mega Smeralda is a cruiseferry owned by Medinvest and operated by Corsica Ferries - Sardinia Ferries. She was built in 1985 by Wärtsilä at the Helsinki New Shipyard in Helsinki, Finland, for Johnson Line as MS Svea for use in Silja Line traffic. Between 1992 and 1994, she sailed for Silja Line as MS Silja Karneval and, between 1994 and 2008, for Color Line as MS Color Festival.
Live Tracking
Most time stopped at Port D' Ajaccio — 8 h across 10 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.
Build Series
Sister hulls share a yard, segment, build year (±1) and deadweight (±3%) — the cleanest comparables for valuation. Derived in-house from our fleet register; coverage is limited to hulls carrying a recorded builder, so a series may be incomplete.
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 8 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.
