In MC 1.9 or 1.9.1pre3 it works, BUT only when boat is in water. I setupped CB with /tp @e[type=Boat,r=3] ~5 ~5 ~ , it works as expected on water , however if player in boat aproaches sliding on ice, it just fails to trigger (repeating commandblock keeps spamming succesful command even though the boat stays on old coordinates. When player disembark, both player and boat seems to be on teleported coordinates. Video: https://youtu.be/2zbcqL1fe8I
