I live along a waterway and have a floating dock I keep my boat at. I have been looking at ways to get the boat out of the water easily without going to the ramp. I have seen home made versions of the Roll-N-Go Roll-N-Go thing out at the coast. Since $800 seems a little bit steep for a glorified trailer without wheels, has anyone built anything like this before? I have been toying with some designs and have been trying to devise a way to winch it all the way onto the trailer. I have plenty of space next to my dock that I could use this and the slope is pretty good. I would build a real ramp, but I don't think I could get the permits approved for it.
