Distances Between United States Ports
Port-to-port calculated distances to help plan your journey
Distances Between United States Ports is published through the coordinated efforts of the Office of Coast Survey, National Ocean Service (NOS) and National Oceanic and Atmospheric Administration (NOAA). This publication contains calculated distances from a port of the United States to other ports in the United States, and from a port in the Great Lakes in the United States to Canadian ports in the Great Lakes and St. Lawrence River. The distance values normally represent the shortest navigable routes, but in certain cases, longer routes that take advantage of currents, avoid ice or other dangers to navigation, or follow required traffic separation schemes are used.
