Seaboard Marine
Seaboard Marine (legal entity Seaboard Marine Ltd.) is a regional specialist headquartered in Miami, USA. Founded in 1983, the line has spent 43 years building out its container service network and today operates a fleet of 30 vessels under the SCAC code SMLU. Total operated capacity stands near 35,000 TEU, placing the carrier among the recognised operators on its core trade lanes.
Seaboard Marine is most active on the following corridors: Caribbean, Central America, Latin America. The line operates on a standalone basis and does not share vessel slots with other ocean carriers under a formal global alliance. Direct customer contact is available via +1 305 863 4444 or the carrier's web portal at seaboardmarine.com.
Seaboard Marine corridor coverage
Seaboard Marine concentrates its services on Caribbean, Central America, Latin America. Customers on these lanes typically see weekly or twice-weekly sailings depending on season and trade balance. For a current sailing schedule, contact the carrier directly or consult its weekly schedule publication.
How to track a Seaboard Marine container
Tracking a Seaboard Marine container starts with confirming the prefix. Look at the container's left-hand corner casting plate or the painted code on the door — the four-letter ISO 6346 owner code is followed by six numeric digits and a single check digit. Blue Water Facts no longer publishes a per-carrier owner-prefix list (see /accuracy/ for why); confirm the operator via the carrier's own tracking portal or your bill of lading. Visit seaboardmarine.com, navigate to the carrier's tracking or "track and trace" portal, and paste the full container number. The portal will return current vessel position, the next scheduled port call, the estimated time of arrival (ETA) and the most recent equipment events such as gate-in, loaded, discharged and gate-out.
If the carrier portal does not return a result, the most likely causes are: the container has not yet been gate-in at the origin terminal, the bill of lading number is in a different format (check whether the system expects an MBL versus an HBL), or the box is moving on a partner alliance vessel rather than a Seaboard Marine hull. In the last case, the schedule data lives with the operating carrier, not the equipment owner. Seaboard Marine's customer service can normally cross-reference the booking and route you to the correct alliance partner. Reach the carrier on +1 305 863 4444 during European business hours.
