ABSTRACT:
Apparatus for the traversal of an air boat or hovercraft over river dams consisting of a two-sided ramp having an upper and lower end. The ramp is constructed in a river extending over a dam. The upper end of the ramp is located upstream of the dam and the lower end of the ramp is located downstream of the dam. Both the upper and lower ends of the ramp are at least partially submerged to permit easy access by a hovercraft. The angle of intersection of the lower end of the ramp with the water, of the upper end of the ramp with the water, and of the upper and lower ends of the ramp is made large enough so that a commercial hovercraft can traverse thereover. In one embodiment of the invention, side flanges are provided extending along the ramp to prevent an air boat once upon the ramp from passing prematurely to either side.
