Since 2006, Grimaldi has been offering the only direct Ro/Ro-container service between the USA and West Africa. The service provides customers with three sailings per month, supported by the ACL marketing network in North America and the Grimaldi Group's unparalleled coverage of West Africa.

The workhorses of this trade are the Repubblica-class Ro/Ro-Container vessels, each having a capacity of up to 700 TEU of containers, up to 300 trucks/tractors/buses and up to 2,000 cars. The service makes direct calls at Jacksonville, Baltimore, New York and Boston in the US, and Dakar, Tema, Lome, Cotonou and Lagos in West Africa, connecting with the Group's extensive range of African ports via transhipment in Dakar.

Grimaldi's direct service is backed up by a four-times-a-week feedering service covering every major North American port from Halifax to Houston. This second service combines ACL’s four transatlantic services with Grimaldi Lines’ five North Europe-West African services via Antwerp and Hamburg.
