Ships is a structure datapack that adds illager ships into the game as a new type of dungeon, and allows illagers use boats.

Structures

Ships

The ships are designed to look like shipwrecks, and the ships contain pillagers, vindicators, and loot similar to shipwreck loot. Ships can spawn made out of different types of wood, and maps from the ships lead you to pillager outposts.

Fleets

Fleets are structures consisting of multiple ships. Each ship has an evoker. illagers will continuously spawn on these until you kill all the evokers. Maps from fleets lead you to woodland mansions.

Illager Boats

This datapack also allows illagers use boats. If an illager is in the water, it will get into a boat and patrol nearby ocean. If it sees an enemy, it will stop patrolling and chase it. Ships spawn with a few patrols around to make getting on board more challenging. Fleets spawn with even more patrols around them.

The Illager boat mechanic is experimental, can be somewhat performance intensive, and might break if you have mods, plugins, or other datapacks installed! If you need to disable or limit Ai boats, you can do so by changing gamerules with "/function ships:gamerules"
