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 215 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.

The invention relates to a system comprising: a foundation element that has a universal joint, wherein the universal joint has a first universal joint element connected to the foundation element for conjoint rotation and a second universal joint element which is rotatable about the longitudinal axis of the first universal joint element by carrying out a rotation about its own longitudinal axis; a floating wind turbine; and a mooring line. One end of mooring line is connected to the foundation element a first connector connected to the second universal joint element for conjoint rotation and the other end of which is connected to the floating wind turbine a second connector rotatably mounted on the floating wind turbine. The system also includes a controller which, on the basis of the rotational position of the floating wind turbine about the foundation element, brings about the adoption of a rotational position of the second connector rotatably mounted on the floating wind turbine; wherein the rotational position of the second connector rotatably mounted on the floating wind turbine corresponds to the rotational position of the second universal joint element about its own longitudinal axis, which rotational position geometrically corresponds to the rotational position of the floating wind turbine about the foundation element.

A deployable marine system for anchoring a vessel in a body of water and to enable a user to ingress into the vessel from the body of water or egress out of the vessel and into the body of water, the deployable marine system includes an anchor-ladder device and a deployment device. The anchor-ladder device includes a first member and one or more steps, the first member including a first end and a second end. The second end is opposite the first end and is associated with an anchoring component that may anchor the vessel. One or more steps may be attached to the first member. The deployment device may be attached to the vessel, connected to the first member in proximity to the first end, and may deploy the anchor-ladder device into, or retract the anchor-ladder device from, the body of water.

A tension foundation is provided for holding a buoyant object in flowing water via a tether. The tension foundation may include a spine component, rotation members rotatable about the spine component, slats, and additional features. The rotation members can include multiple types with distinct dimension ratios, which may be arranged in an alternating pattern. During operation, the tension foundation advantageously provides increased contacting edges to grip an uneven surface, such as a rocky lakebed or river bottom.

A mooring method includes the steps of: transporting a mooring member having a mooring cable which can be connected to a float at one end and an accommodation member installed at the other end of the mooring cable and has an accommodation space therein to a mooring position of the float; accommodating a first heavy weight in at least a part of the accommodation space of the accommodation member at the mooring position; connecting the one end of the mooring cable to the float at the mooring position after the accommodation step; and accommodating a second heavy weight in the accommodation space of the accommodation member by adding the second heavy weight to the first heavy weight or exchanging at least part of the first heavy weight with the second heavy weight at the mooring position after the connection step.

A shallow water anchor system incorporates a four-bar linkage displaceable between a stowed position and a deployed position. The four-bar linkage includes a drive arm pivotally secured at a proximal end on a first fixed pivot point, a pivot arm pivotally secured at a proximal end on a second fixed pivot point spaced from the first pivot point, and a link pivotally connected between distal ends of the drive arm and the pivot arm. A connector is secured between the drive arm and the pivot arm, and a ground spike is coupled with the link. The connector is configured to bias the ground spike downward.
