Jetty vs. Quay — What's the Difference?
By Fiza Rafique & Urooj Arif — Updated on April 4, 2024
A jetty extends from the land into water for mooring boats, while a quay is a platform along the water for loading and unloading ships.

Key Differences
A jetty is primarily a structure built from the shore into the water to protect coastlines and harbors and to moor boats, offering protection against the impact of waves and currents. Whereas, a quay is a concrete, stone, or metal platform lying alongside or projecting into water for loading and unloading ships, typically not offering protection against natural elements but facilitating the transfer of goods and passengers.
Jetties can be found in various forms such as walkways, piers, and breakwaters, constructed for both protection and berthing purposes. On the other hand, quays are designed with a focus on commercial and logistical efficiency, providing easy access for vehicles and cranes to load and unload cargo.
The design of a jetty often includes considerations for minimizing sedimentation inside a harbor or along a coastline, utilizing materials like wood, steel, or concrete. Quays, however, are usually built parallel to the shore and have a straightforward design optimized for cargo handling and storage facilities.
Jetties serve multiple purposes including but not limited to aiding in navigation, fishing, and leisure activities such as walking or sightseeing. Quays, in contrast, are more utilitarian, primarily serving the needs of the shipping industry and waterfront commerce.
While jetties interact more with the natural dynamics of water bodies to influence wave patterns and sediment deposition, quays focus on providing infrastructure for maritime trade, involving extensive handling equipment and storage areas.

Common Curiosities
Can a jetty serve as a quay?
In some contexts, jetties can serve similar functions to quays, especially in smaller or multipurpose maritime facilities, but they are generally designed with different primary objectives.
Is a jetty always built over water?
Yes, jetties are structures that extend from the land out into the water, whether it's a sea, lake, or river.
What safety measures are common on jetties and quays?
Both structures often feature safety measures such as railings, lighting, and signs to guide and protect users.
Are quays used for passenger ships?
Yes, quays are commonly used for both cargo ships and passenger vessels, facilitating easy embarkation and disembarkation.
How does a quay differ from a jetty in purpose?
A quay is primarily used for loading and unloading cargo and passengers, focusing on trade and transportation, whereas a jetty serves multiple purposes including protection and recreation.
Can recreational activities take place on a quay?
While quays are more utilitarian, they can also host recreational activities, especially in urban waterfront areas.
What determines the size of a jetty?
The size of a jetty is determined by its intended purpose, including the size of vessels it accommodates and the degree of protection or berthing space required.
What materials are used to build a quay?
Quays are typically constructed from durable materials such as concrete, stone, or metal to support heavy loads and resist wear from vehicles and cargo.
What role do quays play in global trade?
Quays are crucial for global trade, serving as key points for the transfer of goods between sea transport and land transport modes.
What is a jetty used for?
A jetty is used for protecting the coastline, aiding navigation, providing leisure spaces, and mooring boats.
How do jetties protect against erosion?
Jetties protect coastlines by interrupting wave action and sediment movement, reducing erosion near harbors and beaches.
How are quays designed for efficiency?
Quays are designed with features like flat surfaces for easy cargo handling, access for vehicles, and proximity to storage and transport facilities to maximize efficiency.
Do jetties affect local marine ecosystems?
Jetties can affect local marine ecosystems by altering water flow and sediment distribution, which can impact marine habitats.
How are jetties and quays maintained?
Maintenance involves regular inspections, repairs to structural elements, and ensuring that loading equipment and safety features are in good condition.
