摘要： A launching ramp for boats, float planes and the like has several ramp segments that are in normal use of the ramp, generally aligned and sloping downwardly into a body of water. To enable the easy removal of the ramp from the body of water, the ramp segments are hinged and equipped with stops so that when a cable is connected to the outermost end of the ramp, pulling in on the cable will pivot the outermost end segment upwardly until the stops limit this pivotal movement with respect to the next segment, whereupon the second segment will pivot upwardly to its stop position and so on. As the cable is drawn in, the ramp is rolled up towards the shore. The installation of the ramp is a reverse process of unrolling the ramp into the water. With appropriate modification the ramp may be used as a roll-up dock.
