Abstract: A readily alterable arrangement, to suit the need at sea and in coastal inlet passages for control and disposition of vessels, comprises: pulled barges outfitted with a condition responsive linkage mechanism for implementing a rudder, towlines conveying propulsive force to barges, and tugs continually employed in tow or exchange of barges being loaded/unloaded in the interim of tug port calls. The linkage mechanism, dependent upon a pivotal beam mounted forwardly of the barge mass center, imparts propulsive force on the longitudinal centerline or at either barge side as transmitted to the pivotal beam ends by a bridle leg arranged towline terminal.

Abstract: A pair of impactor elements are fixedly attached to a football shoe along the side and even with the top and sides of the arch of the foot. These impactors are provided with planar ball impacting surfaces which materially increase the area of contact between the shoe and the football. These impactor elements increase punting consistency, ball total flight time and distances and decrease the slicing of the football to one side during punting when the ball is dropped to the right of the centerline of the arch.
