I bought a heavy duty PVC Inflatable Raft, any suggestion on how to safely unload alone?

I got down the inflating part, but when it comes to taking it into the water, what is the best way to do it without having an extra person help carry the otherside? I'm going to be doing a lot of fishing and boating alone, and just don't want to drag the raft on the ground into the water. It weight 68lbs, I'm 5'1, 180. Don't think I can carry it over my head. Any suggestions are very much appreciated. Thanks.
