This issue relates to MC-98160.
After many attempts to break boats, such as dropping them from 250 blocks and sliding them along a long packed ice trail into a wall (and both), I have been completely unable to destroy boats to turn them into planks and sticks.
The boat can be destroyed with lava, however it just drops a boat.
Duplicates very likely MC-98160. In all of the other situations boats are, as far as I know, not supposed to drop planks and sticks.
Relates to MC-98160.
The bug is rather that it normally does not break, but this report is invalid anyways.
The following is based on a decompiled version of MC 1.12 using mcp940.
Please link this in the description of the report.
In the method net.minecraft.entity.item.EntityBoat.updateFallState() you have a piece of code that will always set the fall distance to 0 if the boat is not on land, its actually just wrong placed in the method.
The piece of code: if (this.status != EntityBoat.Status.ON_LAND) { this.fallDistance = 0.0F; return; }
Method with wrong placed: MC-105103-1.png
Method with right placed: image-2018-09-11-21-48-35-190.png
If this is fixed, MC-98160 will be fixed too.
Hope this kinda helps 
Please change the summary to something like "Boat not being destroyed from fall damage" or something similar to make it clear that it is about the boat
Please link to this comment in the description
The following is based on a decompiled version of Minecraft 1.10 using MCP 9.30.
It looks like the reason for this is that the method net.minecraft.entity.item.EntityBoat.getBoatGlide() and probably all the other methods working the same are not detecting the ground below the boat in the tick its OnGround field is set to true. Besides that the method net.minecraft.entity.item.EntityBoat.updateFallState(double, boolean, IBlockState, BlockPos) tests in theory the same condition twice. What it does is that if the boat is on ground, but its status is not ON_LAND it cancels all fall damage. If the getBoatGlide() method worked correctly this should probably never happen, or at least I can't think of any situation right now where this could happen.
If this bug is fixed,
MC-105103will probably work correctly as well.The boat does get destroyed from fall damage if you /entitydata the motion upwards and then when It hits the ground, it breaks and also makes the rider take fall damage.

MC-119369, yet both are confirmed for the same versions... which report is lying about the breakability?EDIT: Ah, wait, I see now after reading comments on that. In that case, this report should clarify it is on mosy y coordinates, but not all.
I am able to confirm this behavior in 21w38a. Here are some extra details regarding this problem.
