The boat often crashes even though I'm several spaces from land or any other object. Getting out of the boat and then hacking to pick it up does not work. However exiting the game and coming back in places the boat about 5 blocks away from it's supposed location. Getting out of the boat in an enclosed area (boat house) will often make the pc appear outside of the enclosure, again about 5 blocks away.
This is similar to MC-31196, however that issue was for 1.6.2 and was resolved so I am re-submitting.
