Harbour vs. Quay: What's the Difference?

Edited by Janet White || By Harlon Moss || Updated on November 2, 2023
Harbour is a sheltered body of water where ships anchor, while a quay is a structure on the shore for loading and unloading ships.

Key Differences

A harbour is a natural or man-made body of water where ships, boats, and barges can seek shelter from stormy weather or are stored for future use. It's often surrounded by breakwaters, piers, or promenades. Conversely, a quay is a specific, man-made structure within a harbour. It refers to a platform lying alongside or projecting into water for loading and unloading ships.
Harbours serve as safe havens for vessels from rough seas, providing anchorage and docking, and can be vast, covering several square kilometers. In contrast, a quay is usually a solid, hard structure fixed in place and is part of the harbour infrastructure used for the specific purpose of cargo handling and passenger entry or exit.
While harbours can exist as natural landforms, they may also be enhanced or built by civil engineering to improve their sheltering capability or to serve larger vessels. Quays, however, are always man-made, constructed along the edge of a harbour or waterfront, and are often synonymous with a wharf or jetty.
Harbours often include multiple quays, docks, and other facilities such as shipyards or marinas, while a quay refers exclusively to the docking area used to transfer goods and passengers to and from vessels. The harbour's size and capacity can impact the size and function of a quay within it.
The terms are sometimes used interchangeably in casual conversation, but they refer to different aspects of maritime geography and infrastructure. A harbour encompasses the overall body of water for anchorage and safety, while a quay refers to the specific waterfront location where ships are loaded and unloaded.
