How far are you planning on "moving" the boat? Would transom mounted launch wheels work? They work best if you inflate and deflate the boat going to and from your destination.
You need to support the tubes and most importantly the transom, with a way to connect the bow. Two to four 2x6's covered in carpet, with aluminum uprights bolted on with square U bolts will work. One or two rollers in the middle will make sure the center doesn't get damaged. One right at the back of the trailer if needed, I don't have one, and one more forward that the keel sits on when parked.
If trailering down the road, you will also need a way to do three tie down points minimum. One at the bow with two at the stern. I see people do one strap over the back, but that can easily change tension with tube pressure, so it is not my favorite way.
