The proposed apparatus is a track table modified by the author from that of Anschutz to determine the time of turning, the advance, and the tactical diameter in the turning trial of a ship. In this track table, the distance travelled by a ship and the change of the direction are simultaneously transmitted to the recording pen from the S.A. L. log and the Sperry-type or the Anschutz-type gyro-compass respectively. Thus the recording pen accurately traces the turning circle. The chief improvements made by the author are the increase of the accuracy and of the magnification of the record. For the purpose of ascertaining the reliability of this apparatus, the author carried out systematic turning trials of two actual ships and compared the records of the one ship with those of the experiments of the model-ship obtained by the "camera" method. It was found that both records agreed fairly well with each other and the "buoy and sight" method hitherto used, could be replaced by the author's method. The discussion of the errors of the apparatus is also appended.
