ABSTRACT:
A marine mooring swivel fitting for connection into a mooring line is a generally dumbbell-shaped element having a relatively slender elongate neck with outward enlargements at the opposite ends of the neck respectively and a mooring line attachment on at least one end of the element. In use the attachment may connect the fitting in the mooring line, the slender elongate neck being adapted laterally to receive swivelly therearound one or more conventional shackles. Such a shackle, depending on whether the swivel is at the upper or lower end of the mooring line, may be secured to a pendant made fast to a marine craft on the surface or secured to an anchoring device. The enlargements, larger than the opening in the shackle, serve to limit the longitudinal movement of the shackle on the element without limiting rotational movement of the shackle around the element.
