Anchor fluke (1) having a hollow plate-shaped body adapted for attachment to a shank and/or anchor lines, with a longitudinal axis and a front penetration edge (3) and a rear trailing edge (4), which are located at a distance from one another in the direction of the longitudinal axis, wherein the fluke has a plane of symmetry that contains the longitudinal axis and is substantially perpendicular to the plate-shaped body. The hollow plate-shaped body has an upper surface (2a) with a centre of gravity and a lower surface (2b) which surfaces are bounded by the penetration edge, the trailing edge and lateral edges (5a, 5b) and wherein the body, at the lower surface, substantially between the edges, is provided with surfaces for counteracting a rolling movement about the longitudinal axis during penetration of the anchor fluke in an anchorage ground, and with vertical trailing edges (13a, 13b) for counteracting a yawing movement about an axis that is perpendicular to the longitudinal axis and is located in the plane of symmetry during the penetration in an anchorage ground.
