Function of anchor

1. The most basic condition for an anchor to work is to catch something at the bottom of the sea.

If the chain is not long enough, the anchor will not work. If the bottom of the sea is flat, or the things that the anchor hooks are not fixed, or the hooks are not very firm, if the waves are calm, it is OK. Once the waves are too large, causing the anchor hook to not hold the things, it will make the anchor lose its function, which is called "walking anchor". During the anchoring period, the ship appears walking anchor, which is very dangerous.

2. The weight of the anchor chain is negligible for the ship, which will not play a great role.

Generally speaking, the anchor chain is straight when anchoring. Do you think there will be any friction in the anchor chain at this time? If you are at the seaside, you will find many small fishing boats, and the anchor chain is thick rope.

3. In the view of the ship, the anchor chain is straight, but there is a section under the water that is close to the seabed, in fact, the anchor is close to the seabed to provide the grip, and then it is transmitted to the ship through the anchor chain, so as to resist the influence of the external load of current and wind wave on the positioning.

The reason why there is a section close to the sea bottom is to consider the influence of the force. There is a section close to the sea bottom, which can provide a margin, which can be within a certain range.
