The player's head gets stuck in the blocks while riding a camel and sailing a boat. If you try to ride a camel into a space 3 blocks high, then the player will begin to take damage, although the crouch mode is activated. The same thing happens when trying to sail a boat or raft into spaces 1 block high above the water. At the same time, on a boat, the player receives damage only at a certain position of the head.
