Ice free port

A port is a location on a coast or shore containing one or more harbors where ships can dock and transfer people or cargo to or from land. Port locations are selected to optimize access to land and navigable water, for commercial demand, and for shelter from wind and waves. Ports with deeper water are rarer, but can handle larger ships. Since ports throughout history handled every kind of traffic, support and storage facilities vary widely, may extend for miles, and dominate the local economy. Some ports have an important military role.

One of the world's oldest known artificial harbors is at Wadi al-Jarf on the Red Sea. Along with the finding of harbor structures, ancient anchors have also been found.

Ports often have cargo-handling equipment, such as cranes (operated by longshoremen) and forklifts for use in loading ships, which may be provided by private interests or public bodies. Often, canneries or other processing facilities will be located nearby. Some ports feature canals, which allow ships further movement inland. Access to intermodal transportation, such as railroads and highways, is critical to a port, so that passengers and cargo can also move further inland beyond the port area. Ports with international traffic have customs facilities. Harbor pilots and tugboats may maneuver large ships in tight quarters when near docks.
