Abstract
A shield device for protecting the front lower portion of a boat or automobile which is trailered behind a towing vehicle via a tongue frame member is constructed of an elongated rigid bar whose extremities pendantly hold paired resilient shield members. A mounting bracket, configured to releasibly attach to the tongue frame member, contains an upwardly directed pivot post which penetrates the elongated bar at its midpoint, thereby permitting pivotal movement of the elongated bar in a horizontal path. Elastic tethers extend from each extremity of the bar to the corresponding extremity of the rear bumper of the towing vehicle. By virtue of such construction, the shield members stay directly behind the rear wheels of the towing vehicle, even on curved roads.
