Unseaworthy
A mod that makes boats unsuitable for ocean voyages.
Quick answer
Which Unseaworthy release should I use?
Unseaworthy 1.4.0-1+1.20.1 targets 1.20.1 with Forge. Installation on the client is optional. Installation on the dedicated server is optional. All 1 required mods have matching files.
Where it goes
Is Unseaworthy required on the client, server, or both?
Installation on the client is optional. Installation on the dedicated server is optional.
The source marks this as usable on both the client and server.
What else does Unseaworthy 1.4.0-1+1.20.1 need?
1.4.0-1+1.20.1. Change the file and its required mods may change too.
Install Cloth Config API (Fabric/Forge/NeoForge) first. We found matching files for this game-version and loader setup.
We only count dependency files that match this setup. A file for another loader does not fill the gap.

About this project
What does Unseaworthy add?
Unseaworthy
This mod makes vanilla minecraft boats unseaworthy. They operate normally on rivers and near shorelines, but as soon as they enter an ocean biome, they begin to be tossed by the sea and eventually break apart.
Features
- Boats deployed on water begin shaking and bouncing upon entering ocean biomes (any biome in the
c:is_oceanbiome tag). - You can optionally set a minimum water depth for boats to sink in tagged biomes.
- A configurable number of ticks later, the boat is wrecked.
- The % chance of being wrecked each interval is configurable.
- Wrecked boats can be configured to:
- SINK: boat is pulled underwater and ejects passengers
- BREAK: boat is broken and drops its item entity
- DESTROY: boat is destroyed and drops a random number of planks and sticks
- Optionally set a miniumum weather condition to sink boats. Defaults to CLEAR (i.e. always sink boats) but can be set to RAINING or THUNDERING.
Datapack Stuff
You can change which types of boat entities sink with the entity tag
unseaworthy/tags/entity_types/sinkable.json
On 1.21.1 it's
unseaworthy/tags/entity_type/sinkable.json
You can change which biomes cause boats to sink with the biome tag
unseaworthy/tags/worldgen/biome/sinks_boats.json
Why would you want that?
I needed a way to encourage players to build actual ships in a mod pack that is all about ocean voyages. Boats are too
good, so I made them worse.
