Abstract

A novel one piece anchor is described for adjustably tethering a rope suspended boat fender against the side of a boat so that the boat fender will be appropriately positioned with respect to the level of a dock against which the boat may be moored. In the preferred embodiment, the novel anchor comprises a substantially elongate member of uniform thickness, one end of which is differentiated into a hook, and the other end of which is rounded. A number of apertures appropriately defined therethrough, at least one of which is disposed near the rounded end thereof receives a rope which is threaded from one side of the anchor through an intermediate aperture, and then around one of the longitudinal edges of the anchor for theading from the same side into a second aperture located near the remote end of the anchor. Once threaded, the intermediate portion of the rope disposed between the two apertures is movable between positions engaging either longitudinal edge of the anchor. When the intermediate rope portion engages one edge of the anchor, movement of the rope is permitted but frictionally retarded by the anchor, whereas when the intermediate rope portion is moved to engage the other edge of the anchor an end portion of the rope is trapped and engaged between the intermediate rope portion and a face of the anchor, to restrain the rope in a tethering position. To unlock the rope from the tethering position, the free end may be pulled with sufficient force toward the rounded free end of the anchor, whereupon the rope will automatically move into an unlocked position for repositioning of the boat fender.
