  • Portable boat ramp for small watercraft
    Patent number: 4696250
    Abstract: A portable boat ramp having a frame supporting a cradle having protective support pads thereon. The frame also includes ground stakes for securing the ramp in a temporary position on the waterbed. A boat may be temporarily moored with the forward portion of the hull in the cradle in a position near the shoreline but with the boat out of contact with the waterbed, thus preventing damage to the boat hull from such contact and the buffeting and wave action normally encountered when the boat is beached.
