English is a sloppy language in which one word may have several popular, but technically incorrect, meanings. The difference between a dock and a pier is one example. The sailing public may think a dock is the same as a pier, but to a professional seafarer the dock is the water adjacent to the pier to which he ties his vessel.
Watery Parking Space
A dock is a watery parking space, while a pier is like a sidewalk. Unlike a dock, a pier is a concrete, steel or wooden transitional structure between water and land. Ashore, you must leave your parking place to arrive at your destination, whether a store, an office or some other facility. You cross a transitional structure, such as a sidewalk, to get to the buildings around the parking lot. Like your parking place, the dock is a defined, albeit watery, place in the water alongside a pier where you park your boat. You walk across or up a transitional structure, a pier, to travel between your boat's dock and the buildings and facilities ashore.
