Abstract
An attachment of a stockless anchor on the sea floor encourages flukes to tilt as soon as the vessel pulls away, while maintaining stability on the floor. The weight of the flukes act as a pivot with the crown of the stockless anchor that, when placed on the floor, causes the anchor to become attached by being buried in the floor when the vessel pulls away. The attachment comprises two claws fastened to the flanks of the flukes at or in close proximity of the crown on the pivot axis of the flukes, thereby enabling them to tilt and become attached immediately in the floor as soon as the anchor is placed on the floor. When the vessel pulls away the anchor is open and becomes attached immediately. An attachment to the floor avoids or reduces dragging of the anchor on the floor.

-10. (canceled)
A stockless anchor comprising:
- two flukes pivotally mounted on a shank, and including a crown, the anchor being characterized by claws positioned on the outer flanks of the flukes or in the proximity of said flanks, which flanks are parallel to or form an acute angle with the shanks, said claws having the following shape:
- height (y) is greater than the height of the crown;
- length (x) is greater than or equal to its width (z);
- the main surface forms an angle with the plane of the fluke, said angle being perpendicular or acute;
- and
- the sum of the main surface areas that are parallel or that form an acute angle with the plane described by the shank during its pivoting is greater than the sum of the main surface areas perpendicular to said plane.
