An anchor system including an anchor having a body member and a first arm pivotally coupled to the body member. The first arm is movable between a closed position wherein the first arm is positioned adjacent to the body member and an open position wherein at least part of the first arm is spaced away from the body member. The system further includes a second arm pivotally coupled to the body member and movable between a closed position wherein the second arm is positioned adjacent to the body member and an open position wherein at least part of the second arm is spaced away from the body member. At least one of the first or second arms has a cavity that is exposed when the at least one of the first or second arms is in the open position. The at least one of the first or second arms includes a protrusion extending therefrom.

An anchor has a fluke, a shank that is connected to the fluke, a coupling to attach the fluke to an anchor line or anchor chain, and an angle adjustment provision to adjust the angle between the shank and the fluke, wherein the angle adjustment provision is a hinge between the fluke and the shank, a first positioning member connected to the shank that is provided with a series of first positioning holes at a first intermediate distance and a second positioning member connected to the fluke that is provided with a series of second positioning holes at a second intermediate distance and spaced apart from the hinge axis, and a positioning pin that is inserted in one of the aligned first and second positioning holes, wherein the second intermediate distance differs from the first intermediate distance.

A method, system, apparatus, and/or device for anchoring a watercraft. The method, system, apparatus, and/or device may include a head and a shank The head may be configured to moor into a vessel to a surface. The shank may be connected to the head. The shank may include a pivot member connected to the head, a first shank arm and a second shank arm connected to the head, where the first shank arm is configured to rotate about the pivot member relative to the second shank arm. The shank may also include a shear member connecting the first shank arm and the second shank arm.

Disclosed is an anchor having a fluke, a shank that is connected to the fluke, and a coupling to attach the fluke to an anchor line or anchor chain, wherein the shank has two shank legs each having a straight shank plate with an outer surface that extend on the opposite sides of the plane of symmetry of the anchor and that diverge from the coupling towards the fluke, wherein the fluke has two straight penetration plates with a top surface on the opposite sides of the plane of symmetry of the anchor, wherein the orientation of the outer surfaces with respect to the top surfaces is specified by three angles under narrow ranges to provide excellent penetration properties and an excellent holding capacity.

A method, system, apparatus, and/or device for anchoring a watercraft. The method, system, apparatus, and/or device may include a head and a scissoring shank. The head may be configured to dig into a seafloor of a body of water to restrict the movement of a watercraft. The scissoring shank may be connected to the head. The scissoring shank may include a pivot member connected to the head. The scissoring shank may include a first shank arm connected to the head by the pivot member. The scissoring shank may include a second shank arm connected to the head. The scissoring shank may include a first hole extending through the first shank arm and the second shank arm. The scissoring shank may include a shear member inserted into the first hole. The shear member may restrict the first shank arm from rotating about the pivot member.
