Abstract
Anchor fluke ( ) 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 ( ) and a rear trailing edge ( ), 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 ( ) with a centre of gravity and a lower surface ( ) which surfaces are bounded by the penetration edge, the trailing edge and lateral edges ( ) 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 ( ) 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.
