  • Patent number: 4216887
    Abstract: Apparatus useful for loading and securing a boat onto a vehicle. Apparatus includes a mounting bolt attached to an end of the boat; mounting bolt having a shaft extending outwardly from the boat and an enlarged head at the outer end of the shaft. A horizontal, tubular bracket is mounted at one end of the vehicle; the bracket has a longitudinal opening extending therethrough, and a longitudinal slot in an upper wall. Mounting bolt engages the bracket with the bolt head within the longitudinal opening. A catch selectively retains the mounting bolt within a midportion of the bracket, or allows the bolt to pass longitudinally along the bracket to an end thereof to engage or disengage the bracket. In further embodiments, the slot is widened adjacent the bracket ends, to allow the mounting bolt head to pass vertically through the slot to engage and disengage the bracket, and stops prevent the mounting bolt from passing longitudinally out of the openings in the bracket ends.
