Bight

Heligoland is located in the German Bight.

A bight is a long, gradual bend or recess in the shoreline that forms a large, open bay.

The Southern California Bight is the curved coastline between Point Conception and San Diego, and encompasses the Channel Islands.

I spied a bight of meadow some way below the roadway in an angle of the river.

I could see every rib, the joints of their limbs were like knots in a rope; each had an iron collar on his neck, and all were connected together with a chain whose bights swung between them, rhythmically clinking.
