An attachment of a stockless anchor on the sea floor encourages flukes to tilt as soon as the vessel pulls away, while maintaining stability on the floor. The weight of the flukes act as a pivot with the crown of the stockless anchor that, when placed on the floor, causes the anchor to become attached by being buried in the floor when the vessel pulls away. The attachment comprises two claws fastened to the flanks of the flukes at or in close proximity of the crown on the pivot axis of the flukes, thereby enabling them to tilt and become attached immediately in the floor as soon as the anchor is placed on the floor. When the vessel pulls away the anchor is open and becomes attached immediately. An attachment to the floor avoids or reduces dragging of the anchor on the floor.

An underwater vehicle includes a plurality of releasable panel members that are initially in a storage state in which the releasable panel members form a closed housing and the underwater vehicle is neutrally buoyant, an actuatable effector that is retained in the closed housing. The effector has an anchor and a positively buoyant upper unit opposite the anchor. When the plurality of releasable panel members are released to open the closed housing, the effector is separable from the releasable panel members and maintained in a vertically downward direction by the anchor and the positively buoyant upper unit.

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.

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.
