A guide as to what are the optimal fluke angles to have for penetration to take place are as follows:
Stiff clay / hard sand: 41°
Mud / soft clay: 50°
Some anchors have the possibility to be set to particular fluke angles, while other types do not have this possibility available. To adjust the fluke angle on anchors that have this possibility, a system of heavy chocks which fits the hinge point of the stock is used to prevent the flukes to exceed the given angle as they open.
