The anchor is the main part of the anchoring equipment. It is an iron ship-stopping device. It is connected to the ship with an iron chain. The anchor can be dropped on the bottom of the water to make the ship stop. The choice of anchor should consider the convenience of operation, easy storage and economical application, but the most important thing is the holding power of the anchor. On the one hand, the holding force of the anchor is not known because of the different types of anchors, and on the other hand, it is related to the soil quality of the seabed.

Most modern anchors are made of cast steel or forged steel, and there are four main types:

Rod Anchor

The claws and the anchor are usually integral, with a crossbar perpendicular to the plane of the claws. Rod anchors are mostly double-claw, and some are single-claw. When in use, one claw bites deeply into the soil and has a strong grip, but due to the cross bar, it is inconvenient to store, so it is mostly used for small ships. The main types of rod anchors are naval anchors, single-claw anchors, Japanese anchors, etc.

Rodless anchor

The anchor claw and the anchor rod can rotate at a certain angle relative to each other, and there is no cross bar. When in use, the two anchor claws are engaged in the soil at the same time, which is convenient for anchor lifting and storage, and is the most widely used. The representative rodless anchors are Hall anchors and their modified Speck anchors.

Large-holding anchor

The anchor claw is wide and can be rotated at a certain angle. There is a protruding rod body in the middle of the anchor head or anchor claw, which plays a stabilizing role. Due to the large area of ​​the anchor claw to bite the soil and the strong grip, it is suitable for the sandy or soft soil bottom. The main types of high-holding anchors are Danforth anchors, Martens large-claw anchors, and speedboat anchors.

Special anchor

The shape is different from general anchors, such as mushroom-shaped anchors. The anchor head is mushroom-shaped or umbrella-shaped. It bites deeply into the soil, has a large grip, and is not easy to move. It is mostly used for long-term anchoring and positioning, such as light boats, buoys, Fixed anchors for barges, etc.
