1. The
anchor connected by anchor chain or anchor cable on the ship is thrown into the water to land on the ground, and it bites into the soil to generate grip and solidify with the bottom of the water, and firmly tie the ship in the predetermined position.
2. When the ship is berthing downstream, in order to ensure safety and avoid U-turn, the stern
anchor is often used to avoid U-turn.
3. When the ship needs to make a U-turn in restricted waters, after controlling the speed of the ship, decide which anchor to drop according to the direction of the U-turn, determine the length of the chain according to the water depth, observe the direction of the anchor chain, and cooperate with the rudder to complete the U-turn operation.
4. When the wind and waves are not large and the hull is not sitting on the reef, an auxiliary anchor can be added in the direction of the scheduled departure from the shallow, and the hull can be left from the shallow by the pulling force of the windlass and the power of reversing.
The anchor generally refers to the
anchor, which is the main component of the anchoring equipment. An iron ship-stopping device, which is attached to the ship with an iron chain, and the anchor is thrown at the bottom of the water to make the ship stable.
The ancient anchor was a large stone, or a basket full of stones, called an ark. Anchorites are sunk to the bottom by ropes, and the boats are moored according to their weight. Later, there were wooden claw stone anchors, that is, wooden claws were tied on both sides of the stone, and the ship was moored by weight and grip. There have been records of metal anchors in the Southern Dynasties of China. Ancient Chinese sailboats used four-claw iron anchors, which have excellent performance and are still used in sampans and boats.
