The Difference Between a Dock & a Pier

Sometimes, people use the same word to mean many things and it can be difficult to decide on the meaning if the word is separated from the context. In the nautical world, a dock and a pier may mean the same thing or have a meaning similar enough to be interchangeable. They may also mean something quite different.

  1. Dock

    • A dock can be a space of water alongside a pier or between two piers where a vessel can load, unload or be repaired. A secondary meaning is the same as a pier. Yet a third meaning is a group of piers called "the docks," which means a general area where ships or boats land.

    Pier

    • A pier is a platform built out over the water on supports called pillars or piles. It functions as a dock (in the first meaning) for watercraft. To an angler, it's something to fish off of. In the entertainment world, it carries such diversions as carnival rides, souvenir shops, nightclubs, restaurants and snack bars.

    Conclusion

    • It would seem that while a dock can be liquid or solid, wet or dry, a pier is always a man-made structure.

    Confusion

    • There are other technical distinctions in the marine field that a landsman has trouble appreciating, such as the difference between a ship and a boat. Some nautical terms have radically different meanings in the landlubber's world--a "sheet" to a sailor is a specific piece of cordage on a sailing vessel, but to his wife, it is an item of bed linen.
