Hall anchors are often used as the main anchors in great medium ships. However, the structure of Hall anchors was complicated, the kinematic behavior and methods for determining the holding capacity of Hall anchors when being pulled in soil are rarely proposed. In this study, a series of model tests was carried out using four scaled Hall anchor models to determine the kinematic behavior, trajectory, and development rules of the holding capacity of the anchors during dragging process. The holding force coefficients of the Hall anchors in sand were identified after the tests. On the basis of limit equilibrium theory of soil, the analytical method of holding force for pulling Hall anchors was proposed. A comparison of the computational results with the test results indicated consistency. The results can provide a good reference for designers.
