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
4 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→ · 12 h in port· draught 7.3→7.3 m· medium confidence
- no cargo change→ · 4 h in port· draught 7.3→7.3 m
- no cargo change→ · 3 h in port· draught 7.3→7.3 m
- no cargo change→ · 14 h in port· draught 7.3→7.3 m· medium confidence
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
3 ports · 33 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.
- Two Harbors· USA26 h2 calls · 13 h avg
- Duluth· USA4 h1 call · 4 h avg
- Rouge River· USA3 h1 call · 3 h avg
Based on 4 completed calls 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 3 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. 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 7.6 m · 79.9 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=2.58 is physically implausible for any cargo ship (declared bulker) — likely a tonnage data error
The declared type conflicts with the class implied by the vessel’s size signals — a possible mis-declaration. Inferred via our shared size-based classifier.

Signals are a current-state view: a flag clears once the vessel stops tripping its detector. These are screening indicators, not a substitute for your own due diligence.

Overview
About This Vessel
M/V Walter J. McCarthy Jr. is a 1000' diesel-powered lake freighter owned and operated by the American Steamship Company. This vessel was built in 1977 at Bay Shipbuilding Company, Sturgeon Bay, Wisconsin and included self-unloading technology. The ship is 1,000 feet (300 m) long and 105 feet (32 m) wide, with a carrying capacity of 80,900 tons (at midsummer draft). The ship carries western coal from Superior, Wisconsin to Detroit Edison's St. Clair Power Plant and Monroe Power Plant in Michigan.
