Update for 1.21.3 released!
You can NOT just drag this file into the datapacks folder! Use "Extract here" and copy the contents of the appearing folders into the folders "data" and "datapacks" inside your world folder!
This datapack adds ships, which can be found out on the oceans while exploring. Some of them will welcome you, others will probably not like it if you come aboard. Current version v18 is for Minecraft 1.21.3. For older versions, see the section legacy versions.
Download the .zip archive and use "Extract here". Then copy the contents of the appearing folders into the folders "data" and "datapacks"! You might want to do /function ercerus:ships/no_spam to reduce the amount of text output during generation.
You can force the generation of a ship by using the command /execute align xyz run function ercerus:ships/ship_event
This datapack was originally made back in 1.13.2 and thus does not use the custom structure mechanics found in current versions. I use the existing big ocean ruins (not the guardian monuments) to determine the location where ships can be generated. You can use the command /locate structure #minecraft:ocean_ruin to find them (Also locates the small one, which won't have ships above them). The contents of the folder: put my contents in the folder named data are map files from 30200 to 30208. These will replace all maps with these IDs in this world! Normally this should not be a problem, only if you have maps with such high ID numbers. In this case, just don't add them to the folder.
This pack is not compatible with all datapacks, which modify the pre-existing ocean ruins (not the guardian monuments).
If you find anything that looks like it's not working as it should, please leave a comment and I will look into it.
Make sure to activate command blocks, if you are using this datapack on a server.

Troubleshooting / Frequently asked questions (FAQ) |
FAQ - Click to open
I can't find any ships.
Make sure to enable the datapack in the datapack selection screen while creating a new world. If you want to use it in an existing world, use the command /datapack list to see all the available ones for this world. The ones in [green brackets] are enabled, the ones in [red brackets] are disabled. Use the command /datapack enable "file/Ships v18 for [1.21.3]" to enable the datapack, if it is not active.
Also make sure that you followed the installation instructions clearly. It will not work if just drag the downloaded file into your datapacks folder. The generation of ships is tied to the generation of big ocean ruins (not guardian monuments). The frequency with which these spawn is determent by the world seed. You may have to search a while before you will find any.
I have multiplayer related problems.
Make sure command blocks are enabled on the server.
Can you increase the spawn rates of ships?
No, because their spawn rate is tied to the generation of big ocean ruins (not guardian monuments).

I can not answer that without knowing, which version of the game you are playing. The current version 18 is for 1.21.3 and also 1.21.2. For all other versions, see the section "Old legacy version". If the version of Minecraft you are playing is not listed in there, then you can't use this datapack.
Just thought I'd let you know, I'm using this on my 1.21 server and it's working fine with a little tweaking.
Mostly just fixing the folder names, but also a couple of edits to some function files and loot tables.
I'd noticed that the bits of paper you have spawning to determine what type of boat to spawn weren't being deleted. After some fiddling, I changed the loot tables from this:
{ "function": "set_custom_data", "tag": "{rnd:cargo_dried_kelp_block,cargo:1}"}
to this:
{ "function": "set_components", "components": { "minecraft:custom_data": { "rnd": "cargo_dried_kelp_block", "cargo": "alternative" } }}
Then obviously I also had to edit the .mcfunction files to reflect the new values for the tags:kill @e[type=item,limit=1,nbt={Item:{components:{"minecraft:custom_data":{cargo:alternative}}}}]
For some reason that I don't understand. The paper with tags with a value of 1 were not being detected by the game, so changing the tags to a text value instead, fixed that problem.
If you want, I can send you my edited files to save you some time updating this to version 1.21.
