The invention has as its object a drag anchor which is simple to manufacture and provides an effective grip in the bottom material where the anchor is to be used, besides which the anchor can be executed with a very low weight. The invention, which relates most particularly to a drag anchor, the shank of which is pivotally attached to its part which forms the fluke, is characterized in that its part (2) which forms the fluke consists of a hollow body (2) open at its front and rear end in the direction in which the shank (1) is towed, i.e. the direction of movement of the drag anchor, which body forms a mantle enclosing the rear part of the shank with an extension in the direction of movement of the drag anchor.
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.
