    The present study aims to investigate the effect of the installation location of two three-component load cells on the results of the captive model tests. The captive model tests consisted of the static drift, pure sway, and pure yaw tests. The test results were analyzed when the load cells were located at 5%, 10%, and 15% of the ship's length from its center. When two load cells were used in the captive model tests, the direction of the sway force of the two load cells was opposite. As the load cells were installed farther from the center, the magnitude and standard deviation of each load cell’s sway force decreased. However, the standard deviation of the yaw moment increased as the yaw moment was calculated by multiplying the sway force and distance. The yaw moment is the sum of the yaw moment value measured from the load cell and the value calculated by the sway force and distance. The yaw moment calculated by the sway force was more than 70% of the total yaw moment acting on the hull. As the load cell got closer to the center of pressure, the ratio of yaw moment calculated by sway force increased.
