Live Tracking
Most time stopped at Port Colborne — 6 d across 2 stays.
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.
Intelligence
How a hull like this loses value with age (today's market). The dot marks this ship at 12 yrs.
Estimate from $/dwt of similar-size, similar-age ships sold in the last 24 months. Indicative, not a certified valuation.

Compliance
On 16 August 2025, the bulk carrier "G3 MARQUIS", while under the conduct of a pilot, reported having experienced a close quarters situation with the sailing vessel "DRAGON D'O" in the St. Lawrence River off Trois-Rivières, QC.
On 11 May 2022, the bulk carrier "G3 MARQUIS" reported being disabled due to a steering gear failure in the Welland Canal off Welland, ON. The crew carried out repairs and the vessel continued its voyage.
On 27 July 2021, the bulk carrier "G3 MARQUIS" reported sustaining a propulsion failure while transiting Lake Erie and proceeded to anchor 8 nautical miles S of Kingsville, ON. The crew carried out repairs which allowed the vessel to resume its voyage.
On 25 May 2021, the bulk carrier "G3 MARQUIS" reported experiencing a problem with one of its generators in the Welland Canal near Port Weller, ON. Once docked in Port Weller, ON, the crew members carried out repairs which allowed the vessel to resume its voyage.
On 25 March 2021, the bulk carrier "G3 MARQUIS" made contact with the breast wall at lock 3 in the Welland Canal, ON.
On 29 July 2020, the bulk carrier "G3 MARQUIS" sustained a main engine failure 4.6 nautical miles ESE of Île aux Sternes, QC. The vessel anchored, the crew carried out repairs, and the vessel resumed its intended voyage.
On 24 April 2020, the bulk carrier "G3 MARQUIS" sustained a main engine failure on the St. Lawrence River off Petite-Rivière-Saint-François, QC. The crew carried out the repairs and the vessel continued on its voyage towards Port-Cartier, QC.
On 06 April 2019, the bulk carrier "G3 MARQUIS" struck the lower ship arrester cable at the Snell Lock, Massena, NY, USA. The St. Lawrence Seaway was closed for approximately 12 hours while the ship arrester cable was repaired. There was no damage to the vessel and no pollution.
Recorded marine occurrences naming this vessel.
Operational Status
Stopped, anchored or moored on its latest broadcast — parked, not necessarily withdrawn.
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.
Arrivals, 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).
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.
Time-in-port summed by port from the AIS-detected port-call history — the ports this vessel has spent the most time at, longest first.
Based on 5 completed calls observed since — open calls (no departure yet) are excluded. The distribution sharpens as AIS history accrues.
Composite Risk
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
Bulker · summer draught 8.1 m · 44.1 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=1.51 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.
