If you start the ship immediately, it will take time. dangerous. Therefore, there is the concept of anchorage.

2. The weight of the Boat Mooring Chain is negligible for the ship, and that little friction will not play a big role. Generally speaking, when the ship is anchored, the anchor chain is straight…
