Everyone on board knows that a ship cannot stop without an anchor. It can be seen from this that the role of an anchor is so great that the anchor chain used to connect the anchor and the hull is even more important. Without an anchor chain, the ship cannot be connected to the hull, and the role of an anchor is lost. Sometimes the anchor chain between the ship and the ship gets entangled.
