Abstract: An assembly is provided for raising and lowering, and for firmly securing, a type of anchor known as a "Bruce" anchor. The assembly includes the rear channel shaped section for receiving the shank of the anchor when it is stowed, and for mounting the assembly on the front deck of the boat. The assembly also includes a forwardly extending section having two side plates which have a roller mounted between them for raising and lowering the anchor over the front portion of the deck of the boat. The roller may be of high strength plastic such as Delrin, and is fairly large, being in the order of 5 inches in diameter and about 3 or 4 inches in width and deeply grooved to receive and center the chain or rope by which the anchor is raised and lowered, and also for engaging the L-shaped shank of the anchor when it is stowed. The front portion of the assembly also includes two protrusions for engaging the fluke area of the Bruce anchor.

Abstract: The anchoring system comprises a combination of two types of anchors. One anchor comprises an anchoring element of the plough type and a shank. The plough has the shape of a dihedral having lateral edges contained in a common plane perpendicular to the bisecting plane of the dihedral. The corner edge of the dihedral is inclined toward the common plane from one end of the corner edge in the vicinity of which end the shank is fixed to the plough. The other anchor comprises an anchoring element of the "sheet" type and a coupling device for coupling the element to pulling apparatus. The element has a part-cylindrical surface whose concavity faces the coupling device and is curved in the direction of the span of the surface so that any tangent to the part-cylindrical surface in a plane perpendicular to the axis of the part-cylindrical surface is orthogonal to the direction of the pull exerted on the anchor in service.

Abstract: An anchor includes a fluke attached to a shank having a forwardly located cable attachment point. The fluke includes concave side surfaces, and these side surfaces can serve to orientate the anchor to an upright burial position by interaction with the sea bed and to stabilize the anchor when buried in the sea bed. The fluke side surfaces are also arranged, either by relative orientation thereof or by the inclusion of a flat fluke portion interconnecting the side surfaces, such that, when the anchor is pulled through the sea bed, the peak pressure focus zone produced by the sea bed soil on interaction of the fluke with the soil is located clear of the shank and clear of the forward path of burial movement of the shank.

Abstract: A mooring anchor made up of a solid, heavy, cylindrical body from which extend rigid upper and lower cross arms that have flukes at the outer ends. The cross arms are spaced at ninety degree intervals around the circumference of the body. The upper cross arm is located appreciably higher on the body than is the lower cross arm. An eye affords a convenient means of attaching a chain or cable. This anchor is intended to provide a good means of anchoring buoys to bottoms that are either of sand or mud. It has no moving parts.
