In
geography,
bight has two meanings. A bight can be simply a bend or curve in any geographical feature, usually a coast. 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).
