Abstract
Abstract An apparatus for loading and unloading a boat onto and off of a carrier, and which includes a stand adapted for mounting on the carrier having a loading winch mechanism for retracting a loading line detachably connected to the boat''s stern for raising the boat bow first from the ground into a generally verticallyoriented position. A guide assembly movingly supports the boat''s bow after reaching a predetermined raised, vertical position, and a booster assembly is selectively engageable with the boat''s stern to then pivot the boat toward a generally horizontal position. The guide assembly supports the boat, when in a horizontal position, for movement in a forward direction into the loaded position on the carrier. An unloading winch assembly retracts an unloading line detachably connected to the bow for moving the boat rearwardly while the stern is connected to the loading line to unload the boat. The loading winch assembly includes a brake assembly which retards paying out of the loading line against the force of gravity on the boat for easing the boat onto the ground. The booster assembly is re-engageable with the stern of the boat during the unloading operation to further facilitate easing the boat onto the ground.
