Apparatus is disclosed for automatically loading and unloading a boat relative to the top of a camper vehicle. The apparatus provides a movable linkage mechanism adapted to be secured to the top of the vehicle. A pair of parallel arms connected to the gunwales of a boat is supported on the movable linkage mechanism. A spring means is provided for enabling the movable linkage mechanism to rotate the arms with the boat thereon in one direction, and a cable means is provided for enabling the movable linkage mechanism to rotate the arms with the boat thereon in the opposite direction. The movable linkage mechanism is effective in reducing the height of the swing of the boat being rotated through an arc of 180 DEG between a rest position contingent to the ground in the back of the camper vehicle and an inverted rest position on the top of the vehicle, and is further effective in balancing the boat on the movable linkage mechanism during the swinging thereof such as to facilitate and minimize the power required to accomplish the movement.
