(Summary description)There are four kinds of ship anchors, they are: rod anchor, rod anchor, high holding power anchor and special anchor. 1. There is an anchor Also known as the navy anchor, this anchor is an early anchor, also known as the navy anchor, the anchor structure is simple, grab weight ratio is large, grab the bottom stability is good, but the anchoring operation and collection is not convenient, the upwarped anchor is easy to tangle the anchor chain and scratch the bottom of the ship, this anchor is not easy to be used as the bow anchor of the merchant ship, generally used for small boats or sailboats. 2. Rodless anchor Also known as mountain anchors, commonly known as Hall anchors and Spaker anchors, are rodless anchors with active anchor flukes (about 45 degrees of rotation along the anchor stem), and the anchor rod and anchor arm of the rodless anchor are cast separately. Anchor claw, anchor crown and anchor arm cast into one. The anchor shaft is inserted into the rectangular hole of the anchor crown, and the pin shaft and the cross pin are positioned in the two semi-circular grooves at the lower part of the anchor crown to realize the purpose of turning the anchor shaft. 3. Large holding power anchor The high gripping power anchor combines the advantages of rod anchor and rod anchor, and is generally a rod rotary fluke anchor. Commonly used are Martenberg anchor, Danforth, which is characterized by wide and long claw, deep biting soil, good stability, so as to obtain a larger gripping force, gripping weight ratio of up to 11-17 times. But the strength of the anchor claw is weak and easy to deform. Because of the large resistance unearthed, it is generally only suitable for engineering ships, and some do spare anchors or tail anchors. 4. Special anchors A special purpose anchor, often used for permanent mooring on floats, buoys, light boats, floating docks and floating docks. There are single claw anchors, spiral anchors and fungus anchors.
