Concerning on the measurement of ship's motions in a seaway, 5 of ship's motions of 6 freedoms as a rigid body in a space, that is, rolling, pitching, surging, swaying and heaving, could be measured by newly deviced apparatus which consisted from Vertical gyro, Stabilized plate and Transducer for 3 dimensional accelerations. The block diagram of this apparatus is shown in Fig.2. The view of entire instrument is shown in Photo. 1 and also the stabilized plate with sensing elements is shown in Photo. 2. The example of the record of motions by this apparatus is shown in Fig.8. The maximum values of acceleration in heaving motions and its power spectra are indicated in Table 2 and Fig.9, respectively ; the later were computed by HIPAC 103 Electric Digital Computer in Center of Hokkaido University.
