A device is presented that can be used as both a pad eye and as a fairlead independently and simultaneously while providing separation between the two modes of use. The device provides the option for multiple attachment points and multiple fairlead passages and reduces the need of requiring both a pad eye and additional hardware such as a pulley in applications such as the implementing of a jib sheet in-hauler system on a sailing vessel. Additionally, the device is configured in a symmetric manner so as to allow the device to be optionally joined and mated to a second but inverted such device allowing for the assembly of two such devices into a single combined unit. Such a combined configuration has the benefit of allowing for pad eye and fairlead functions to take place in a suspended location instead of being constrained to only a fixed surface.

An underwater towing device, including an underwater towing assembly and a fixing mechanism of the underwater towing assembly. The underwater towing assembly includes a first floating body, a second floating body, and a third floating body. The fixing mechanism includes a fairlead carrier and two supports disposed on two sides of the fairlead carrier. The first floating body, the second floating body, and the third floating body are connected together via a fixing frame. The first floating body, the second floating body, and the third floating body have streamlined and bilaterally symmetrical shapes and all are hollow to accommodate experimental equipment. The first floating body is a cylinder having a drop-shaped horizontal cross-section. The upper part of the first floating body is provided with a buoyancy reserve tank having an elliptic horizontal cross-section.

Protective polymer covers for metal equipment are disclosed. The metal equipment is generally used with wire ropes, and the protective polymer covers provide a smooth protrusion free surface which is suitable for contact with a synthetic line. The protective polymer covers are shaped to conform to an outer peripheral surface of the metal equipment, and include at least one cover section having at least one means for connection at each of a first end portion and a second end portion. The protective polymer covers are composed of a thermosetting cast polyurethane having a Shore D hardness of greater than about 60 or a Shore A hardness of greater than about 85.

A fairlead for guiding an anchor chain, intended to equip a ground anchor system for a floating platform, includes a bending structure for guiding a direction change of the associated anchor chain, and a locking structure that includes a grip jaw consisting of two jaws associated with operating elements for rotatably moving the jaws in opposite directions. The operating elements include: (a) an inert mass, referred to as counterweight, which is movably coupled to the jaws and which is height-adjustable between a low position and a high position corresponding to an active position and an inactive position of the jaws, respectively, so as to operate and tend to maintain the jaws in the active position, and (b) an actuator driven by control elements, for operating the jaws from the active position to the inactive position and for operating the counterweight from the low position to the high position.

Provided herein is a Mooring Line Restrainer capable of withstanding the whiplash from the impact of a snapped mooring line, and including a contoured Restraining Member shaped to engage and restrain snapped mooring lines and incorporating a single or multi-turn spring, mounted on a framework attached to one or more support bases. At least one of the support bases is a magnetic holding device adequate for different sizes of mooring lines, for securely and strongly fixing the Mooring Line Restrainers on the deck of a ship at appropriate positions along and on either sides of the mooring lines as per a mooring layout plan. The support bases have provisions for interlinking the plurality of adjacent or alternate Mooring Line Restrainers for forming a strong structure around the mooring lines for confining and restraining any snapped mooring lines within a narrow zone around their pre-snapped positions on the ship's deck.

A boat winch assembly including a mounting bracket for securing the assembly to a boat, a winch subassembly supported by the mounting bracket and including a spool for an anchor line, and a drive motor for rotating the spool, a spar having an outer end with one or more rollers, an anchor line retaining member, and a fairlead that is defined between one of the rollers and the anchor line retaining member, wherein in use, the anchor line passes through the fairlead, and a hinge connection, such that the spar projects outwardly from the hinge connection, where the hinge connection enables the spar to rotate between a deployed position and a stowed position and when the boat winch assembly is secured to a boat, inclination of the spar increases with rotation of the spar about the pivot axis from the deployed position towards the stowed position.
