Live Tracking
Current Position
Where it waited most
Most time stopped at Port of Keelung — 31 h across 1 stay.
- 1Port of Keelung31 h
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 at the vessel’s passage speed. A destination is the crew’s stated intent, not a confirmed fixture.

Risk & Sustainability
Build Series
Sister Vessels
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
Activity
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.
Port calls
1 recent · AIS-detectedArrivals, 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).
- no cargo change→ · 32 h in port· draught 8.3→8.3 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.

Based on 1 completed call observed since — open calls (no departure yet) are excluded. The distribution sharpens as AIS history accrues.
Composite Risk
Risk Score
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.
Estimated
Capacity & Classification
Other · summer draught 8.2 m · 28.8 t per cm immersion
Estimate only — modelled from deadweight (deadweight regression) using a first-principles hydrostatic model, not measured hydrostatic tables. The design draught it is anchored to is unreliable across the fleet.

Overview
About This Vessel
Diamond Princess is a British-registered cruise ship owned and operated by Princess Cruises. She began operation in March 2004 and primarily cruises in Asia during the northern hemisphere summer and Australia during the southern hemisphere summer. She is a subclassed Grand-class ship, which is also known as a Gem-class ship. Diamond Princess and her sister ship, Sapphire Princess, are the widest subclass of Grand-class ships, as they have a 37.5-metre (123 ft 0 in) beam, while all other Grand-class ships have a beam of 36 metres (118 ft 1 in). Diamond Princess and Sapphire Princess were both built in Nagasaki, Japan, by Mitsubishi Industries. There have been two notable outbreaks of infectious disease on the ship – an outbreak of gastroenteritis caused by norovirus in 2016 and an outbreak of COVID-19 caused by SARS-CoV-2 in 2020. In the latter incident, the ship was quarantined for nearly a month with her passengers on board, and her passengers and crew were subject to further quarantine after disembarking. At least 712 out of the 3,711 passengers and crew were infected, and by mid-April 2020 nine had died.
