How anchor holds the ground?

We can distinguish two means by which anchors setting:
 Static Setting

Static setting depends on gravity—in otherwords, weight—to penetrate the seafloor. This setting mode is typical for monstrous Ship anchors weighing anywhere from several hundred pounds to several tons, which are designed to sink into the seafloor from their sheer weight alone.

Anchor

Dynamic Setting

 Dynamic setting complements static setting, using the load on the anchor rode and the resistance of the seafloor to embed the fluke or blade. Anchors that lie on their sides to set (such as the Bügel, Manson Supreme, Spade, Sword, and Rocna) generate torque once rode pull is applied, which twists the blade into the seabed.

Two parameters are critical to dynamic setting in virtually all Seabeds:

  • The proper setting angle, and
  • The amount of downward force at the tip.
