22 VARIABLE RATE BOAT LOADER ABSTRACT OF THE DISCLOSURE A variable rate boat loader includes a frame having transverse front, rear-powered and rear-pivot rollers. Two pulleys are mounted on the boat gunwales between the boat's bow and center of gravity. Two winch lines are connected at one end to the powered roller in laterally spaced position. Each line extends forward atop the vehicle, upward around the front roller, and back over the frame and lengthwise of the boat to the pulleys. The lines extend through the pulleys, forward to the frame, over the pivot roller to be supported thereby, and down to the stern of the boat. The lines are supportingly connected to the stern of the boat. This arrangement provides a doubled mechanical advantage in lifting the boat from the ground up to the level of the frame. From this level, as the effective load being lifted decreases, the mechanical advantage decreases while the lifting speed increases. The winch lines automatically bind the boat to the front roller and pivot roller when the boat is fully loaded.
