Chain grapnel hooks are used for recovering an anchor and chains that have been detached from the buoy and have fallen to the seabed. The head eye of the grapnel is attached to the trawl cable and the tail eye may be attached to the trailing cable for the purpose of withdrawing the grapnel in the event that the flukes engage with an “immovable” object on the sea bed. Grapnel is designed with catch slots at the root of the flukes which will retain anchor chain up to 4 inches.
