抄録

The paper describes on the sidewise forces generated by propeller action. The results of model experiments on 2 right-hand single-screw ships, not underway, are as follows: -(1) When the propeller revolves going ahead and the rudder is amidship, ship tends to fall off to port, as usually. The ratio of sidewise forces, at that case, to forward thrust generated by propeller are 2〜3%. (2) When the propeller revolves backing, the sidewise forces are reversed, that is, her stern moves to port. The ratio of that forces, at that case, to stern thrust are 15% or so, independing to rudder angle.
