Anyone got any info on a boat moving device?

Here's a thought, while at the grocery store today I watched a man use a remote-control unit to haul about 20 grocery carts into their store. You might check some of the larger stores and see if they might sell you a used one and convert it to adding a towing ball. Who knows you might get one really cheap.

That sounds like a good idea, I'll have to look at one more closely the next time I see one. Thanks for the idea.
