Abstract: Apparatus for generating an animated image when viewed from a location in motion. The apparatus comprises a series of images; and at least one illumination device for emitting light flashes adapted to illuminate the images. Ignition devices are provided for causing a light flash to be emitted each time the location has moved a distance substantially equal to the spacing between two successive images. The illumination device is fixed relative to the images and is adapted to simultaneously illuminate an entire section including the series of images.A method of providing an animated image for viewing by a viewer at a location in motion relative to a series of stationary images. The method includes sensing the velocity of motion of the location relative to the series of images. A series of the images is illuminated for viewing from the location as the location moves past the images. The illumination device for flash illuminating the images is fixed relative to the images.

Abstract: A multi-hulled vessel and the hull design for the hulls of a multi-hulled vessel capable of operating as a hydroplane are presented. Each of the hulls of the multi-hulled vessel are of hydrostatically and hydrodynamically identical configuration. The forward portions of the oppositely disposed sidewalls of the hull are conically shaped and the rearward portions are planar; the forward portion of the base of the hull is cylindrically shaped and the rear portion is planar; and the stern is planar. The two conically shaped front portions of the hull sidewalls are interconnected at an acute angle by a common generatrix which forms the front bow or stem of the hull, and the cylindrical portion of the base of the hull has a horizontal generatrix. The conical sidewall portions and the cylindrical base portion are each tangent to their respective rearwardly disposed planar elements.
