2.) Put cart on the east line of the claim, don't put the cart onto the claim though just close.
3.) Bring container to the very edge of the claim, put it on the left side of the cart and walk off the plot, now lift the container from outside of the plot.
4.) Put the container into the cart, then pull the cart away from the claim.
Container/liftable object can now be taken and placed anywhere.
What does this mean? You can now steal with trespassing and leave no summonable scent.
Edit; I'd have to test this from all angles but as far as I can tell so long as you can put the object you want to steal next to the edge of someone's claim you can do this from all positions, the exceptions are placing the object behind the cart sprite because it stops you placing it close enough to the edge.
Edit; Now with pics!

Edit; Confirmed this does work with boats.
