Abstract
An anchor includes at least one elongate member attached to the shank and fluke of the anchor and having at least two elongate surfaces substantially curved lengthwise and disposed at least one at each side of the said plane of symmetry of the anchor, said elongate surfaces together being symmetrical about the said plane of symmetry and lying substantially in a plane transverse to said plane of symmetry relative to the shank member. In the anchor arrangement, said transverse plane is orientated such that when a portion of the elongate surfaces is in engagement with the mooring bed, the anchor is dragged over and relative thereto by a pull on the cable, the centre of pressure on the engaged portion of the elongate surfaces is constrained by the elongate surfaces to travel along the elongate member thereby increasing in separation from the cable attachment point on the foremost extremity of the shank member and decreasing in separation from the centre of area of those portions of the fluke member burial surfaces which furnish a maximum projected area on a plane at right angles to the plane of symmetry of the anchor whereby forces are generated between the elongate member and the mooring bed which roll the anchor to a final working burial attitude wherein the fluke member engages the mooring bed.
