<p>The invention comprises an anchor including a shank which in cross section along at least part of its length has forward and rearward facing edges and a pair of side faces between said edges. The parts of the shank adjacent the forward edge are substantially v shaped in cross section and at least part of the side faces between the edges are concave. The anchor further includes a fluke having a forward end and a rearward edge in normal use, the rearward edge having a continuous flange extending therefrom over at least a substantial part of the rearward edge. The anchor has a roll-bar positioned substantially above the upper surface of the fluke forming a semi-circular wheel spanning the width of the fluke and wherein along at least a substantial part of its length the roll-bar is in cross section substantially in the form of a foil.</p> |
