The U.S. Navy Lightweight Mark 2 anchor weighs 6,600 lbs. It was used on small yard and patrol crafts and it was used by Landing Ship Tanks (LST’s) as a stern anchor. When approaching a beach, this anchor is dropped as the vessel nears the shore and upon completion of the offload. It is used to winch the LST back into deeper water.
The chain that is draped around the anchor pad and coiled around the anchor support post is not really an anchor chain. It is the chain that drives the gear that raises and lowers the actual anchor.
