I placed a boat beside a wall and half of it is showing now but its also shacking very violently and it doesn't stop. If you enter the boat you can't get out. The button to leave the boat might just show only once. Testing this in Minecraft Windows 10 Edition is probably the most effective.

Steps to reproduce

• Make a wall. (Doesn't matter how tall really)
• Place boat next to wall until it goes through the wall and shakes.
