A ferry slip is a specialized docking facility that receives a ferryboat or train ferry. A similar structure called a barge slip receives a barge or car float that is used to carry wheeled vehicles across a body of water.

The word dock in American English refers to one or a group of human-made structures that are involved in the handling of boats or ships. In British English, the term is not used the same way as in American English, it is used to mean the area of water that is next to or around a wharf or quay. The exact meaning varies among different variants of the English language.
