A portable marine anchoring device maximizes holding capacity while anchored into the ground. The device is fabricated from lightweight aluminum.

Weak soil anchor device (1) for anchoring a number of structures, as well as method for arranging an anchoring in weak soils. Seen in a vertical operating position, the weak soil anchor device (1) comprises: an elongate inner continuous open box structure (2) with a triangular cross-section comprising a first wall surface (3), second wall surface (4) and third wall surface (5), an outer continuous open box structure (10) with a smaller vertical extent than the inner box structure (2) and having a triangular cross-section consisting of a first outer wall surface (11), second outer wall surface (12) and third outer wall surface (13), the vertical center area (14) of the first, second and third outer wall surfaces is connected to the inner elongate continuous open box structure (2) in a lower area of respectively an outer edge area between the first and second wall surface (3, 4), second and third wall surface (4, 5) and the third and first wall surfaces (5, 3), and anchor brackets (20) are arranged in a lower outer area of the weak soil anchor device (1), where the weak soil anchor device comprising the inner and outer box structure (2, 10) is lowered down into the weak soils to a desired depth.

A mooring system for an Ocean Wave Energy Converters (OWEC) includes multiple structural members such as legs and braces that are linearly extendible and connected using mobile joints, each joint providing two degrees of freedom for rotations about the joint. Mobile joints also attach bottom ends of the legs to mooring points. A jacking system can change lengths of the extensible structural members to adjust depth of the OWEC for operation or for storm safety, to lift the OWEC out of the water for maintenance, or to align the OWEC to an incoming wave direction.

A collapsible anchor for lightweight watercraft includes a handle member, including a left grip and a right grip, wherein the left grip and right grip are located across a central member from each other; a first tube member, the first tube member attached to the handle member and extending downward in a vertical orientation from the handle member; a second tube member, the second tube member removably attached to the first tube member and extending downward in a vertical orientation from the first tube member; and an auger member, the auger member attached to the second tube member and extending downward in a vertical orientation from the second tube member.

A novel emissions control watercraft (STAXcraft) solving a long-felt but unsolved need regarding disadvantages associated with prior-art emissions servicing watercraft, the disadvantages selected from the group, but not limited to, the use of tugboats, securing or mooring servicing watercraft to a serviced vessel, additional expenses and time-delays and inefficiencies of land-based approaches, increased toxic emissions, increased greenhouse gases (GHG) emissions, danger from falling cargo, tanker safety, alongside mooring in narrow channels preventing other OGV's to pass safely, and cargo tank emissions.

An anchoring device made of an elongated shaft, a bracket with an L-shaped cross section, and an angled portion connecting the two. The anchoring device is configured to accept or connect to a beach or boating accessory at one end and insert into the ground at the other end. An alternate embodiment of the device includes a weighted portion that is located above the point where the shaft meets the angled portion of the device.

A restraining device, such as a bolt, pin, or latch, removably secures a connector sleeve to a U-bolt, such as a tow-rope-eyelet on the bow of a boat hull. The connector sleeve is machined with an internal cavity having surfaces and dimension that correspond to outer surfaces of the U-bolt. The sleeve contains holes through which the restraining device passes after the sleeve has been slid over the U-bolt such that the restraining device, while installed, prevents the sleeve from sliding back off of the U-bolt. The sleeve also includes accessory mount holes to receive restraining devices that attach an accessory, such as a ladder, to the sleeve and thus to the boat via the sleeve that has been secured thereto. The sleeve may provide for set screws to snug the sleeve to the U-bolt if clearance exists between surfaces of the cavity and the U-bolt.
