A boat tunnel system apparatus and method for providing shallow operation of a boat when utilizing standard outboard motors. A convex tunnel having a forward end, a convex center section, and a rearward end that exits the stern of a boat above the water line ensures that water adheres to the convex tunnel as the boat moves forward through the water thereby causing water to exit the stern of the boat above the normal water line. As the boat gains speed, water exits higher and higher above the normal water line and, in conjunction with the convex tunnel, a movable motor with propeller attached can be lifted into the solid water stream exiting the stern of the boat. As the boat reaches a plane position, a solid stream of water is provided so far above the normal water line of the boat that the propeller and water intakes of a motor can be raised above the water line and, in fact, raised above the hull of the boat. As a result, the boat utilizing the boat tunnel system of the present invention in conjunction with a movable motor, can be operated in extremely shallow waters, limited only by the draft of the boat itself.

A boat tunnel system comprising: A. a boat with a hull, bow, and stern; B. a convex tunnel formed in said hull exiting said stern above a water line of said boat so that as said boat travels through water, said water adheres to said convex tunnel as said tunnel exists said stern above said water line and flows upwardly above said water line as said water exits the tunnel at said stern; and C. a movable motor means, with a propeller, attached to said stern so that as said water exits said convex tunnel and flows upwardly therefrom, said propeller is raised within said upwardly flowing exiting water until said propeller is above said water line.
