Shipwreck is a structure found mostly in ocean biomes, but can occasionally generate on beaches, snowy beaches, or embedded in icebergs. It resembles a sunken sailing ship, often in a state of disrepair, and may appear upright, sideways, or upside-down. Rarely, a Shipwreck generates fully intact.
Shipwrecks are made of wooden blocks and typically contain up to three chests, depending on which parts of the ship are present. The bow contains a supply chest, the upper stern has a treasure chest, and the lower stern holds a map chest.
Supply chests may contain food, coal, leather armor, and TNT. Treasure chests often hold iron, emeralds, gold, lapis lazuli, or diamonds. Map chests always include a buried treasure map, alongside paper, feathers, and books.
Each Shipwreck uses a limited combination of two wood types for its construction. Although their appearance varies, shipwrecks offer a chance for good loot and access to treasure maps that lead to buried treasure.
