The present invention discloses a bionic high holding power anchor, which includes an anchor rod, a suspension clasp coupled with one end of the anchor rod and an anchor fluke hinged with the other end of the anchor rod, wherein a plurality of fluke heads arranged at equal intervals are extended from a front end of the anchor fluke, fin-like streamlined balance wings are arranged at two sides of the anchor fluke; the fluke head is in a shape of triangle-like taper containing a plane side wall and two curved side walls, the plane side wall is an isosceles triangle, the two curved side walls are smooth curved surfaces, and the two smooth curved surfaces are symmetrical around a normal plane of the plane side wall. According to the bionic high holding power anchor of the present invention, the balance wings are arranged at the two sides of the anchor fluke, a body is avoided from being turned completely and the anchor reaches to a soil layer at a correct working angle during a process that the anchor is thrown into water; and a longitudinal dimension of the anchor is increased, so that an anti-turning property of the anchor in the soil layer is improved significantly, and a risk of anchor dragging is reduced.

A tethering device for use in securing a boat to a dock is mounted to the underside of the dock decking with its deck trim assembly flush with the top of the dock and only the looped, running end of the tethering line extending from a hole in its deck trim assembly. Threaded studs welded to the underside to the deck trim assembly enable its line retraction mechanism and line locking mechanism to be supported below the decking leaving the deck surface free of tripping hazards and excess line. Below the decking, an assembly cover houses a self-retracting reel and a line-locking mechanism for control over the line, retracting excess line but enabling the user to set and hold the length of line needed for tethering a boat to the dock.

Systems are provided for a fairlead, and in particular to a hawse fairlead. In one example, the fairlead may include a wear insert positioned within a first opening of a fairlead frame configured to guide a rope and/or cable. The wear insert may be constructed from a denser material than the frame.

Systems are provided for a fairlead, and in particular to fairlead including an integrated lighting system. In one example, a fairlead may comprise a frame, the frame including a central, first opening and a second opening disposed above the first opening. The second opening may house an integrated lighting system, the integrated lighting system including a plurality of lights.

A retractable deck pin for cooperating with a boat line includes a cylindrical pin body which is axially movable in a pin guidance by an underdeck positioned actuator. A seal element is positioned in a clearance for sealing the pin body with respect to the pin guidance. The retractable deck pin is improved by providing a reservoir filled with an oil volume. The reservoir which is positioned under the pin guidance has a reservoir opening for receiving the pin body in the contained liquid volume. An air inlet is provided with a non-return air valve. When moving the pin base into the liquid volume, an air volume above the liquid volume will get pressurised. An airflow escapes from the reservoir via the clearance to the ambient. The air flow through the clearance counteracts a possible incoming flow of leaking.
