A bight is a bend or curve in a coastline, often forming a bay or a cove. It is typically characterized by a wide, open area of water that is partially enclosed by land. Bights can be found in various geographical locations and are important for navigation, fishing, and recreation. In addition to coastal bights, the term can also refer to a specific type of knot used in sailing, known as a bight knot. This knot is created by forming a loop in a rope without crossing the ends, making it useful for securing lines or creating mooring points.
