A new energy utilization project developed by Tokai University was started in 1991. It was ordered to develop high-speed one-man water racer fully using solar power. In 1994, a new type watercraft was launched, that was full-submerged hydrofoil craft with 480W solar power. Her dynamical performance was tested during sea trials and improved year by year. This paper discusses the new maneuvering method of the hydrofoil craft with two struts and a tandem hydrofoil system. Her motion's control system was quite simple. Without any automatic control, roll motion stabilized by the driver's weight shift and steering like bicycle or motor cycle. This paper proposes a new equation of motion to describe her turning motion. The results of the numerical analysis show, which concerned the stability of the lateral motions and yow-roll-sway coupled turning motions.
