Impossible to get planks/sticks from boats in 1.9+

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.

This relates to MC-98160 and MC-105103.
