Anchor Line Trip Hook was primarily designed for Marine Industry, it is very useful in returning and setting anchor around marine pipe cable loop or eye and wind it on winch drum of tug boat. When anchor is off ocean floor and boat reaches its desired distance from barge, the boat begins to release the winch line. When anchor hook reaches approximately half way off stern of boat, insert small hook on hold back line in bottom hole of anchor line hook. When releasing winch line further, the hold back line will get tight causing the anchor line hook to trip or release loop or eye of buoy cable automatically.
