When a boat hits soul sand block at water surface level it breaks. In previous versions the should sand will slow boat and stop it but not break it.

Interesting. Tested it again. It seems to happen between 5 and 10 percent of the time and only when going at high speed. Happens in creative more it seems.
Can reproduce in 1.8 in survival. Docked boat in line of soul sand as gently as I could but docked pretty far into boat and jumped to land. After 36 seconds of bobbing in water and stuck in sand, boat broke into sticks/planks. Three more tests with similar results. Tried again with soul sand barely touching boat and boat survived at least 2 minutes (still there as I type this).
My guess is boats docked too far are bumping into the land and breaking after bouncing a while.
Can't reproduce in 14w31a.
