High speed crafts have entered on a new phase of seeking motion-less and noice-less ride comfort responding to customer's needs. Hitachi Zosen developed a hybrid craft Superjet 3O based on a concept of 'fully submerged hydrofoil plus catamaran', which can satisfy both such new needs and basic requirements for speed, seaworthiness and cost-performance. Superjet 30 provides a better ride comfort compared to other types because of a smaller vertical acceleration and pitching motion due to the damping effect of the hydrofoil. The motion control system further improves the ride comfort. The system is effective also for improving the seaworthiness in coastal waters and availability factor in operation. Sea trials and commercial operations revealed the folloving effects of the motion control system: The roll control reduces the ship's motion by 50 %; the bow height constant control provides an optimum attitude for propulsion, which results in the improvement of the propulsive performance. The paper describes the overview of Superjet 30 and the performance of the motion control system.
