ABSTRACT:
A boat and utility trailer including an elongated, cylindrical wheel rotatably mounted on the trailer axle between the conventional trailer wheels to support the trailer on sand, mud or the like as the trailer is towed over soft terrain by a vehicle. In a preferred embodiment the boat and utility trailer is characterized by a horizontal tongue support provided with an axle support or bracket extending vertically downwardly from each end of the tongue support. An axle extends through the axle supports and a trailer wheel is journalled for rotation on each end of the axle. A tongue extends forwardly from the tongue support and is fitted with a trailer hitch on the extending end for connection to a towing vehicle. The elongated, cylindrical wheel has a diameter slightly less than the diameter of the trailer wheels, is journalled for rotation on the axle between the axle supports and carries the trailer over dirt, sand or mud when the conventional trailer wheels begin to sink in the soft terrain as the trailer is towed by the vehicle. In another preferred embodiment the tongue may be removed from the tongue support and disassembled to facilitate space-efficient storage of the boat and utility trailer when the trailer is not in use.
