Abstract

Anti-fouling sling hook (10) with latch (32) that comprises a forged hook (12) of selected design to provide a wider curved surface in the throat (48) of the hook to provide a better bearing surface for a cable, and an improved design of hook (10) and latch (32) so that the latch is of greater strength and, in closed position, straddles a projecting stub (22) on the tip (20) of the hook, which resists any outward or sidewise movement of the latch. The latch is also designed to provide a smooth contour in conjunction with the outer surface of the hook and hook tip, so as to be anti-fouling.
