PURPOSE: A catamaran shaped sailing yacht using kayaks is provided to enjoy riding a yacht in crowds and to enjoy as a kayak in itself when wind is not blown. CONSTITUTION: A catamaran shaped sailing yacht using kayaks(1) comprises a buoyancy device and a steering device. The buoyancy device is mounted on a sit-on-type kayak. A seat in the kayaks can be used as a passenger seat. One additional seat is arranged in a space of a body for supporting the kayaks. The weight is distributed to both kayaks in balance regardless of the number of passengers to prevent overturn due to wind. A double steering device is applied to the steering device so that the passengers seating in any seats can steer. The angle of a ventral fin installing in the center part of the body of the steering device can be controlled to control windages due to the wind.
