ABSTRACT:
A self-locking, quick release, latched, antifouling hook comprising a J-shaped body encircling a bowl with a latch pivotally attached to the body and held in contact with the hook tip, under spring tension, thus closing the throat of the hook. A spring tensioned, lever arm is pivotally attached to the latch and, in the locked position, is rigidly held engaged to the J-shaped body. Such a hook can be readily opened by intentionally compressing the lever arm into the latch and then, continuing with the same motion, the latch is opened by further compression of both the lever arm and the latch, into the bowl of the hook.
