From Openwaterpedia

noun - A strait or Straits is a narrow, typically navigable channel of water that connects two larger, navigable bodies of water. It most commonly refers to a channel of water that lies between two land masses, but it may also refer to a navigable channel through an open body of water that is otherwise not navigable, for example because it is too shallow, or because it contains an unnavigable reef or archipelago.

Numerous artificial channels, called canals, have been constructed to connect two bodies of water over land, such as the Suez Canal. Although rivers and canals often provide passage between two large lakes or a lake and a sea, and these seem to suit the formal definition of straits, they are not usually referred to as such. The term strait is typically reserved for much larger, wider features of the marine environment.


The terms Channel, Firth, pass or Passage, and sound can be synonymous and used interchangeably with strait, although each is sometimes differentiated with varying senses. Many straits are economically important. Straits can be important shipping routes, and wars have been fought for control of these straits.
