Technical Specifications
Overview
HSF Cruise Bonaria is a Ro-Pax high speed ferry, built in 2000 at the Sestri Ponente shipyards by Fincantieri and owned by Grimaldi Lines previously owned by Minoan Lines as Knossos Palace. It can accommodate up to 2,500 passengers and 700 cars, and has 758 beds plus 742 airseats for passengers. The vessel is powered by four Wärtsilä 16V46C diesel engines with a combined power of 67,517 kW (90,542 hp), which give her a top speed of 31.6 knots (58.5 km/h; 36.4 mph). In November 2020 Minoan Lines announced that Knossos Palace exchanged with her former ship Cruise Bonaria previously named Olympia Palace. The first sold to Grimaldi Lines and renamed it Cruise Bonaria and the other one renamed Knossos Palace. The former Knossos Palace was under the Minoan Lines 20 years. For 20 years did the Piraeus-Heraklion route. The ship left Greece on 24 November and arrived at Napoli, Italy after two days.
Live Tracking
Most time stopped at Civitavecchia: 4 d across 27 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
An older hull, stopped, whose last broadcast is itself no longer fresh: a cautious lay-up proxy.
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. “Likely laid up” is a cautious proxy (an old hull, stopped, with a non-fresh fix), not a confirmed lay-up. 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 65 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.
