Simple Submarines
by SappyInsane
Simple Submarines lets players explore the seabed in two underwater vehicles, a small craft for four and a large one for eight.
What it does
Two types of submarine are added, both built for underwater exploration. Players take them into the sea to look around. The submarines let the pilot breathe underwater, need no fuel, and are described by the author as simple to run. Players bring their own night vision, since the vehicles do not provide it. The mod runs on NeoForge for 1.21.4 only, and is needed on both client and server, so every player and the server need it. Its license is custom and the project is not open source, although the source code and issue tracker are public.
