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.
Intelligence
Risk & Sustainability
This ship has no verified emissions report. We estimate a band C from its segment, size and age (62% confidence).
Estimate, not a reported figure. Within one band 95% of the time on reported peers.

Safety Record
- TOTAL FAILURE OF ANY MACHINERY OR TECHNICAL SYSTEMMinorAug 18, 2022Kingsville, ONTARIO (ON)
On 18 August 2022, the bulk carrier "PAUL R. TREGURTHA" reported sustaining a port main engine failure in Lake Erie off Kingsville, ON. The vessel proceeded to the nearest anchorage for repairs.

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→ · 5 h in port· draught 7.1→7.1 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.
Where it waits
1 port · 5 h totalTime-in-port summed by port from the AIS-detected port-call history — the ports this vessel has spent the most time at, longest first.
- Duluth· USA5 h1 call · 5 h avg
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
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.
Estimated
Capacity & Classification
Bulker · summer draught 8.1 m · 66.3 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.
density DWT/GT=1.90 is consistent with declared bulker
Declared type is consistent with the class implied by the vessel’s size signals. Inferred via our shared size-based classifier.

Overview
About This Vessel
MV Paul R. Tregurtha is a Great Lakes-based bulk carrier freighter. She is the current Queen of the Lakes, an unofficial but widely recognized title given to the longest vessel active on the Great Lakes. Launched as MV William J. De Lancey, she was the last of the thirteen "thousand footers" to enter service on the Great Lakes, and was also the last Great Lakes vessel built at the American Ship Building Company yard in Lorain, Ohio. The MV Paul R. Tregurtha is the current flagship for the Interlake Steamship Company.
