With several types of rudders of a single screw Ship, i.e., 5 kinds of stream line balanced rudders, of which one without and the others with fair waters in front of them, the following model experiments were carried out : -<BR>(1) Propulsion.<BR>(2) Measurements of turning force experienced by the ship when the rudder is put over and the propeller is working.<BR>(3) Measurements of normal pressure, lift and drag on the rudder and twisting moment in the rudder head, when the rudder is put over in both cases of going ahead and astern, while the propeller is working.<BR>The results of experiments are shown in a table and curves annexed.
