In geography, bight has two meanings.
A bight can be simply a bend or curve in any geographical feature—usually a bend or curve in the line between land and water.
Alternatively, the term can refer to a large (and often only slightly receding) bay. It is distinguished from a sound by being shallower. Traditionally explorers defined a bight as a bay that could be sailed out of on a single tack in a square-rigged sailing vessel, regardless of the direction of the wind (typically meaning the apex of the bight is less than 25 degrees from the edges).
