Abstract
An anchor comprising an exterior bale and having two fluke planes in a horizontal plane that lie vertically parallel and in a horizontal plane are separated by vertical ribs uniting the horizontal planes at an angle of 90.degree. and forming with them open spaces between the fluke planes that allow the passage of marine floor material through the entire length of the fluke planes area. Stops elements are to either side of the fluke plane and control the burial angle rotation of the fluke in relationship to the bale.
