ABSTRACT:
A retractable tongue for a boat trailer, the retractable tongue including a slide and a slide housing, the slide being pivotally connected to the slide housing by a pin fitted through elongated slots in each side of the slide housing. The structure is enclosed in a housing to protect it from the elements and the housing has holes on each side of it through which a locking bar can be passed to lock the retractable tongue in a dropped down, inoperable position to thwart unauthorized use of the trailer. When the locking bar is removed, the slide can be rotated into an operable position and slid forward and locked into position for towing. A coupler is attached to the free end of the slide to provide a brake actuator between the towing vehicle and the trailer. The remote end of the slide is terminated at an angle to the axis of the slide so that the slide can rotate within the slide housing a pre-determined distance to an inoperable position, but the slide will not rotate beyond a controlled point, thus forcing the slide to terminate in a dig-in position that would prevent the trailer from being towed should an unauthorized user attempt to move the trailer.
