Estuary vessels are authorized to sail both inland waters and determined sea routes. The Montana shares many features with seagoing vessels. The Montana is a complete bunker ship that was finished in Heusden in very close cooperation with its owner (in both the preliminary process and the finishing), the classification societies and the Belgian shipping inspectorate.
