Shipwreck

Shipwrecks are, as their name suggests, generated structures resembling sailing ships that are found in most of the Overworld’s aquatic landscapes.

Generation
Shipwrecks generate naturally in all ocean biomes. On rarer occasions they may generate beached (above sea level), inside icebergs, or inside of underwater ravines.

Structure
Shipwrecks resemble classic vessels or caravels. They generate in one of three ways: upright, keeled sideways, or upside-down. In many cases, they are missing their bow (front) or stern (rear), mast, and multiple other blocks, giving them a damaged appearance; however, it is also possible, but rare, to find them completely intact. They consist solely of wooden materials, including logs/stripped logs, planks, fences, slabs, stairs, trapdoors, a door (if the ship is upright), and up to 3 chests, depending on rotation and intact sections of the ship. The bow is supposed to generate one chest (unless upside-down) while the stern should generate two, and the whole ship generates a maximum of three chests, regardless of the ship's rotation or condition. However, there are some instances in which chests that usually generate in a shipwreck section are missing. All variants of wood (except acacia and birch) are used in the shipwreck's structure, but only two wood types are used per ship.

Loot


Shipwrecks contain up to 3 loot chests, depending on the sections still intact. Supply chests generate in the bow of the ships, treasure chests generate in the upper section of the stern, and map chests in the lower section. In the case of certain shipwrecks, especially those that intersect other structures, the chests that would normally be present in the corresponding section may be absent, resulting in some shipwrecks holding no chests at all. Although chests don't usually generate for missing sections, map chests from shipwreck sterns may generate in upside-down bows even if the stern is missing. Furthermore, each shipwreck with at least 2 chests always contains its map chest.
