Bight (geography)
Shallowly concave bend or curve in a coastline, river, or other geographical feature
In geography, a bight (/baɪt/) is a concave bend or curvature in a coastline, river or other geographical feature, or it may refer to a very open bay formed by such a feature. Such bays are typically broad, open, shallow and only slightly recessed.
01Description
The size of bights differs greatly, which may be as small as a bend in a river or large like a sound. Large bights are shallower than sounds. 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).
According to the United Nations Convention on the Law of the Sea, an indentation with an area as large as (or larger than) that of the semi-circle whose diameter is a line drawn across the mouth of that indentation, can be regarded as a bay not merely a bight.
02Etymology
The term is derived from Old English byht ("bend, angle, corner; bay, bight") with German Bucht and Danish bugt as cognates, both meaning "bay". Bight is not etymologically related to "bite" (Old English bītan).
