About PIONEER BAY
PIONEER BAY is a Italy-flagged Roll-on/Roll-off registered under IMO 9203642 (MMSI 664722293) and currently associated with the Port of George Town, Cayman Islands. Vessels in this class belong to the broader roll-on/roll-off (ro-ro) facility family — operationally that means cargo handling and voyage planning are dominated by pure car and truck carriers (PCTCs), ro-pax ferries, and project cargo ro-ro tonnage. Stern and side ramps allow wheeled cargo to drive on and off, supported by paved marshalling yards capable of staging thousands of vehicles or trailer units between vessel calls. She measures 222 metres in length overall by 33 metres in beam, with a gross tonnage of 328,791 GT and a deadweight of 373,626 tonnes.
The vessel is currently shown as underway, meaning her AIS transponder is reporting a course and speed consistent with passage between port calls. Her current declared estimated time of arrival is May 2, 2026 05:42 UTC, although ETAs are routinely revised in transit to reflect weather, routeing and pilot scheduling. She was built in 2013. The vessel is registered with the International Maritime Organization, whose database of registered ships and the conventions governing their operation is published at the IMO conventions library.
IMO numbers are issued by IHS Markit on behalf of the International Maritime Organization and remain attached to the hull for the lifetime of the vessel â they do not change with sale, re-flagging, or rename. MMSI numbers, in contrast, are issued by the flag state’s telecommunications administration and identify the vessel’s radio installation; an MMSI changes when a vessel changes flag. When researching an individual ship across historical records â particularly for incident investigation, port state inspection history, or insurance claims â the IMO number (9203642) is the stable identifier to anchor the search on, while the MMSI is the right key for AIS reception logs and VHF radio licensing records.
The vessel’s declared dimensions of 222 metres length overall by 33 metres beam, with 328,791 gross tonnage and 373,626 tonnes deadweight, place her in a specific size class within the global roll-on/roll-off fleet. These particulars determine which port berths she can use, which canals she can transit (Panama Canal locks, Suez Canal draught, the Strait of Malacca’s Malaccamax constraint), and which terminals around the world have the cranes and yard plant to work her efficiently.
