As a high-speed passenger ship, a new concept "Hi-Stable Cabin Craft" is introduced and its technical feasibility was investigated. The "Hi-Stable Cabin" implies highly motion-stabilized cabin, which is mechanically supported by the main ship hull by means of a hydraulic supporting system, with which ship's vertical motion is automatically controlled so as to be suppressed into zero. Therefore, acceleration in the cabin is well minimized so that the passengers will enjoy a trip even in a rough seaway. Computer simulation was carried out regarding the motion control of the Hi-Stable Cabin Craft in waves, and it was confirmed that high degree of stabilization was possible. Model experiment was carried out by use of 3.8 meter-long ship model of the Hi-Stable Cabin Craft equiped with a electroservo mechasism supporting system. Measured pitching motion of the cabin was less than 1/8 of that of the main hull, and remarkable reduction of motion of the cabin was attained. Technical feasibility in practical design of the Hi-Stable Cabin Craft was studied from various aspect such as, general arrangement, hydraulic system, cabin structure, stability, economy of operation, etc. compared with a conventional high-speed craft. As a result, it was considered that the Hi-Stable Cabin Craft appeared to be one of the promissing concept of the advanced marine vehicle for the future.
