Seamoths!
by HydraGenisys
Seamoths! brings the Subnautica submarine-style vehicle into Minecraft, a pilotable Seamoth that travels faster underwater than swimming.
What it does
The mod adds the Seamoth, a vehicle taken from the Subnautica games, which the player crafts, deploys and pilots. It is meant for deep-sea exploration: a player can reach ocean monuments, shipwrecks and open water faster than on foot or by swimming, and it suits adventure maps and survival worlds alike.
Seamoths! is a Forge mod for 1.20.1 only. It runs on the client and the server, so both need it, and it is not open source: it is released under All rights reserved. Forge files were first published on 2026-03-15, and the latest is 1.5.5 for 1.20.1, dated 2026-09-01. A NeoForge build was temporarily removed because of a bug the author has not yet fixed.
Key features
Pilotable Seamoth
The Seamoth can be crafted, placed in the world and driven by a single pilot at a time.
Fast underwater travel
The vehicle moves through water at a higher speed than a swimming player, shortening trips across ocean floors.
Deep-sea exploration
The Seamoth is built for exploring the depths of the sea, bringing Subnautica's underwater technology into Minecraft oceans.
Adventure focus
The vehicle is intended for exploration gameplay, such as searching for ocean monuments and shipwrecks.
