What does "inland" refer to in maritime terms?

In maritime terms, "inland" specifically refers to anything shoreward of the line of demarcation. This line typically separates inland waters from ocean waters and is crucial for regulatory purposes, as it delineates which laws and navigational rules apply. In the context of shipping and boating regulations, inland waters are often regulated differently than those in open ocean areas, with particular attention to factors like waterway width, depth, and adjacent shorelines. Understanding this distinction is essential for operators to comply with local laws and ensure safe navigation.

Other terms provided define different areas relevant to maritime navigation and regulation. For instance, “anything seaward of the line of demarcation” refers to offshore waters, while “any area covered by navigable waters” encompasses both inland and offshore areas, thereby lacking the precise focus needed. Open ocean areas primarily describe the vast expanses of water far from the shore, distinct from the concept of "inland."
