Abstract: A horizontal, generally rectangular frame structure constructed from aluminum, or iron, longitudinal and transverse beams mounted on the interior surface of a pick-up truck. The frame structure having one or more pairs of longitudinal boat support members, or channels, mounted on the top surface. The channels having a top cover of a low coefficient of friction plastic material are spaced to accommodate the keel structure of a jet-ski. Auxiliary pairs of channels are removably connected to the rear ends of the truck-mounted channels extending downwardly to the ground surface. An electric powered winch mounted on a vertical support on the forward portion of the frame structure accommodates a cable that is removably attached to the bow of the jet-ski. The jet-ski with its bow placed on the channels and connected to the winch cable is pulled up onto the truck body when the winch motor is energized.
