Abstract
An anchor orientating device (1) to ensure that an anchor (2) comes over a ship's stern roller (3) on its back i.e. fluke outermost comprises an elongate body (4) carrying a transverse cordioid shaped cam (5) inclined backwardly on the body (4), the front of the body (4) being adapted for attachment to an anchor cable (7) and the rear, in substantial non-rotational manner, to an anchor. Reaction of the cam (5) with the roller surface causes device (1) to rotate so as to pivot the anchor to a fluke outermost position and to bring a stabilizing cam land (16) into engagement with the surface. The device (1) additionally includes a secondary reaction surface (20) which reacts with a smaller diameter bolster bar (21) of an anchor rack to further rotate the anchor and so enable the anchor fluke (2A) to engage the bolster bar (21) for anchor store.
