Abstract
Abstract In the simulator for shooting down the rapids in accordance with the present invention, a platform is installed on one side of a water channel in which a boat moves, and a theater zone is installed on the other side. In the theater zone, a boat swaying device and a wind generating device are installed, and these devices are successively operated in synchronization with the picture projected on a screen in the theater zone by a projector. Also, according to the present invention, three spherical seats are arranged in an isosceles triangle form under the boat moving in the water channel, and three vertically movable swaying rods are installed under the water channel in the theater zone at the positions corresponding to the spherical seats.
