A navigable channel is a body of water that is deep enough and wide enough to allow for the PASSAGE of boats or ships. The term can be broken down into three parts: WATERWAY (8 letters), PASSAGE (7 letters), and fairway (7 letters). A WATERWAY is a large body of water, such as a river, lake, or ocean. A PASSAGE is a route or path through which something can pass, such as a boat or ship. A fairway is a navigable channel in a body of water, such as a river or lake, that is wide enough and deep enough for vessels to pass through. Together, these three terms describe a navigable channel, which is a body of water that is suitable for navigation by boats or ships.
