  • They function according to hang glider aerodynamics.
    • Players don't receive fall damage if they fall from a small height while flying slowly (not nose-diving).
    • Players still receive fall damage if they nose-dive directly into the ground.
  • Have to be equipped in the "chestplate" slot in order to work.
  • Have 431 uses and can be repaired on an anvil using leather.
    • When the durability reaches 1/432, elytra will not break or take damage. Instead, they will stop working and the texture changes to broken looking elytra.
  • Can be given the Unbreaking enchantment using an anvil or commands.
  • Legs will make a "walking movement" animation when you are stalling in the air.
  • Found on End Ships within an item frame, replacing the beacon/Searge's book
  • They fold in when not in use.
  • Capes don't display while wearing.
  • Takes damage at a rate of 1/s.
  • Similar to the Wing Cap item from Super Mario 64.

Command format[]

NBT tags
  • All entities
    • Passengers (list): Replaces the original "Riding" compound tag. It has the ability to specify multiple passengers at equal depths, unlike "Riding". Instead of the deepest-nested "Riding" entity being the bottom-most in the stack of riding entities, the entity at the root of the data is at the bottom of the stack. For example, the armor stand in the following command is at the bottom of the stack while the cow and pig are at the same depth:
      • /summon ArmorStand ~ ~1 ~ {Passengers:[{id:"Cow"},{id:"Pig"}]}.
    • Riding (compound): The "Riding" tag has been removed in favor of the new "Passengers" tag.
  • Players
    • RootVehicle
      • With the introduction of the "Passengers" tag, this new compound holds a copy of the entity the player is currently riding. "AttachLeast" and "AttachMost" are the UUIDLeast and UUIDMost of that entity, while "Entity" holds the actual data.
      • /testfor @a {RootVehicle:{AttachLeast:1l,AttachMost:1l,Entity:{id:"Boat",CustomName:"Test"}}}.
  • Boats
    • Type (string): Determines the wood material of the boat that is displayed. Values are: oak, spruce, birch, jungle, acacia, dark_oak.
      • e.g. /summon Boat ~ ~1 ~ {Type:"acacia"}.


Non-mob entities[]

  • Now are larger, somewhat slower (until 15w42a), and have oars which the player rows.
  • Six different kinds of wood boats are available, corresponding to the types of wood.
    • Only oak boats may be crafted, due to MC-89942.
    • The NBT tag Type (string) have now added for the boat entity, taking values oak, spruce, birch, jungle, acacia and dark_oak.
  • Changed how player movement is sent and processed by the server, making boats much less susceptible to client/server position desync than they had been.
  • Boats are now much less fragile, no longer being destroyed by collisions while in the water, though they can still be destroyed by fall damage onto the ground.
  • Crafting recipe now includes a wooden shovel for the oars.
  • Now require oar movement to move, using the left and right keys – these controls were changed in a later snapshot, 16w04a.
    • The left key will paddle the left oar, turning the boat to the right – and vice-versa.
    • Holding both left and right will paddle both oars, propelling the player forward. Rapidly pressing left and right in alternation will make the boat travel even faster.
    • Using the mouse, the player can look fully to the left or to the right, but not behind. This does not turn the boat.
    • Holding the forward, back or sprint keys no longer have any effect.
  • The player cannot use or attack with items in hand while the boat is in motion. This was changed in 15w42a.
  • All entities can go into boats, with a maximum of two entities (including the player).
  • Mobs can no longer control boats.

World generation[]

End ships




  • Mojang cape texture modified. The capes will also not be seen if the player is wearing elytra.
  • Improved cheat detection.
