There are many important tools used on board. These important tools facilitate the navigation of the ship. The most important equipment for the ship is the chain and anchors. These equipment are vital to the movement and stopping of the ship. The anchor must have a quality structure. Otherwise, the anchor will be dysfunctional during the ship's stop. The ship must stop at the required time. Failure to do so may result in ship accidents.

The anchor must be suitable for the size of the vessel or vessel. An unsuitable anchor will not be able to slow down and ultimately stop the ship. The chain is formed by the addition of links. The tensile strength of these materials is very high. Therefore, these equipment are used continuously during maritime activities.
