Legal Definitions - harbor line

A harbor line is a boundary that marks a specific area of public water that is reserved for a particular purpose.

For example, in New York City, the harbor line marks the boundary between the navigable waters of the Hudson River and the non-navigable waters of the city's harbor. This line is important because it determines which parts of the waterway are subject to federal and state regulations and which parts are under the jurisdiction of the city.

Another example of a harbor line is the line that marks the boundary of a designated anchorage area. This line is important because it helps to ensure that ships do not anchor in areas that are unsafe or that could interfere with other vessels.

In general, harbor lines are used to help manage and regulate the use of public waterways, ensuring that they are used in a safe and responsible manner.
