Abstract: The new boat ramp has a ladder-style frame having C-shaped elongated lateral side rails held in spaced apart parallel condition by C-shaped cross support beams. One end of the frame is a water end and the other end is a shore end. At least six hull roller assemblies are mounted on the side rails in laterally paired relationship across from each other and in longitudinally spaced relationship. One lateral pair is at the water end. Each assembly has a roller axle carrying a hull roller at each end. The assemblies are mounted so that their axles are in pivotable elevated transverse orientation above the side rails so as to provide hull conforming support for a boat. A keel assembly having a central keel roller of significant axial length in at the water end.
