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.

Crew ETA

Resolved from the live AIS destination. Distance is the real sea route (around land and through canals). “Off the port” is steaming time only; “likely alongside” adds the wait this port has actually kept comparable ships for. The queue is a typical case, not a promise — berth waits vary far more than they average. A destination is the crew’s stated intent, not a confirmed fixture.

A quick estimate: the median $/dwt of 2 similar-size, similar-age ships sold in the last 24 months, not re-timed to today's market. The full valuation blends several models over recent sales adjusted for size, age and market moves, so its consensus value can differ from this figure. Indicative, not a certified valuation.

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.

Flag registerno data

A coverage-weighted blend of the single component 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.
