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.

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.
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 10.24 m · 41.3 t per cm immersion
Estimate only — modelled from deadweight (deadweight only) 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=2.41 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.

Behavioural flags raised against this vessel — each shown with the raw evidence behind it. Derived in-house from data we are entitled to publish; informational, not a determination of wrongdoing.

Method: declared type vs size-implied class (DWT/GT density + beam/LOA fullness). Source: vessel_type_audit (sibling P3#3 job; shared coarse_class 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
MV John J. Boland is a diesel-powered lake freighter owned and operated by the Buffalo-based American Steamship Company (ASC), a subsidiary of Rand Logistics. This vessel was built in 1973 at Bay Shipbuilding Company, Sturgeon Bay, Wisconsin. Initially named Charles E. Wilson, the vessel was renamed to its current name in 2000. She is a self-unloading vessel, with a 250-foot (76 m) boom, mounting a conveyor belt, that could be swung to port or starboard. The ship is 680 feet (210 m) long and 78 feet (24 m) wide, with a carrying capacity of 34,000 tons (at midsummer draft), limestone, grain, coal or iron ore.
