  • Boat trailer tongue lowering jack
    Patent number: 6003892
    Abstract: Small boats being trailer launched from steep ramps are in danger of spilling water over the transom if the bow is held high by the trailer. The invention is for a two component jack screw mechanism that can lower the trailer tongue below the trailer hitch without disconnecting it from the towing vehicle. One component coupled to the trailer tongue has a vertical tower that fits within a second tower attached to the second component that is coupled to the trailer hitch. A manually operated crank attached to a jack screw within the two towers lowers the tongue and the bow of the boat so that the boat may float from the trailer.
