The author carried out the model experiments in a wind tunnel. Analyses of the results found the importance of the normal acceleration which acts on the bow of the ship. And the following results were found through further investigation on it. (1) The principal factor which affects the magnitude of cable tension acting steadily on the anchor cable is the lateral velocity of the center of gravity of the ship. (2) Regarding the impulsive cable tension, there are three significant factors in the magnitude of cable tension ; a) the slackness of the anchor cable at the furthest extent of the swing motion, b) the angular velocity about ship's center of gravity, c) the lateral velocity. The above factors should be taken into account to moor a ship safely with a single anchor.
