<p>A boat loader and unloader having a vertical column post adapted to be mounted on a usual trailer hitch at the rear of a vehicle. A horizontal bar is mounted on the top of the column post and has a pair of spaced roller assemblies mounted thereon. An elongate carriage formed by a pair of spaced parallel rail members is slidably and pivotally mounted on the horizontal bar by the roller assemblies, A real assembly having a crank operated bar is adapted to be mounted transversely across and secured to the mid-portion of a boat. A take-up cable is attached to and extends between the reel bar and one end of the carriage. The other end of the carriage is adapted to be clamped to a boat transom when the boat is in a horizontal position on the ground with carriage extending vertically downwardly from the top of the column post. Actuation of the crank operated bar winds the cable about the bar pivoting the boat about the clamped end of the carriage from a horizontal to a vertical upstanding position. The bottom of the boat then can be lifted upwardly manually to pivot the carriage from a vertical to an inverted horizontal position on top of the column post. The boat then is pushed forwardly manually to slide the carriage along the roller assembly to move the boat to a forward storage position on top of a vehicle with the front of the the boat being supported by a vehicle mounted rack and with the rear of the boat being supported by the vertical column post. A reverse operation enable an individual to manually unload the boat from on top of the vehicle.</p> |
