Abstract: A boat anchoring means includes, beside the conventional anchor, a number of sinker bodies attached to the hawser rope, adjacent to the anchor. In order that these sinkers shall not cause damage to the hull or equipment, and provide a good grip during hauling-in, each sinker is formed as a symmetrical body of rotation, is covered by a soft shell, and is maintained at the rope by a tubular wedge member adapted to be driven into a tapering, axial passage through the sinker.
