Thats what I did
Most transport cos. have a tralier with a sliding platform: the cradle is blocked up and one edge sticks out beyond the blocks. Trailer is backed up under that edge and the cradle edge is let down on the sliding platform. Then the blocks on that end are removed and the trailer backed-up to the other end beyond the blocks so the rear end is over the back of the trailer (there are a couple of recesses in the back of the trailer to allow the trailer to back up past the rear blocks). Once the trailer is positioned the remaining blocks are removed and the whole cradle is now on the trailer, lock it down and go anywhere. Cheaper than a hydraulic trailer move, plus yards don't have to block/unblock the boat. Provided your yard doesn't try to sheister like mine....AD
