Hi. I know this must sound like a stupid question, but I need to get my newly aquired 13' boat off the trailer for repair and paint in my garage. My first thought was to lower the hitch to the ground and somehow block up the stern and then raise the hitch letting the stern down on the blocks. That would get the stern off the trailer. But now what do I do? How do you get the bow up and off? It's not a big boat but it's heavy. 1958 fiberglass over plywood. What kind of a cradle do I have to build to support the boat? Any thoughts? Thanks.
