Eureka! Ships! for Valkyrien Skies (Forge/Fabric)
by rubydesic
Eureka Ships lets players turn ordinary and modded blocks into ships that move under physics, as an add-on for Valkyrien Skies.
What it does
A build is assembled from ordinary blocks, and a Ship Helm placed on it starts the conversion. Shift and right-click the helm to assemble the structure, and the finished build gains physics instead of staying fixed in place. The mod keeps a vanilla look while adding this behavior.
Valkyrien Skies is required and provides the physics framework this add-on builds on. Kotlin For Forge is needed on Forge, while Fabric installs need Fabric API, Fabric Language Kotlin and Mod Menu. A server running it needs every connecting player to have it too. Builds are published for Fabric and Forge across four game versions, 1.16.5 – 1.20.1, under the Apache License 2.0, and the code is open source.
The project is in alpha, and its author warns that bugs are expected, so worlds should be backed up before use. Assembled ships are meant for players who accept that the mod may change between releases.
Key features
Ship Helm assembly
A Ship Helm placed on a block build converts it into a ship when activated with a shift and right-click.
Physics on builds
Assembled ships move under physics, so static constructions can float, drift and sail.
Ordinary and modded blocks
Any block in the build can become part of a ship, including blocks added by other mods.
Alpha status
The mod is in alpha, so its features may change between releases.

Who it’s for: Players who already use Valkyrien Skies, and server owners who want physics-based builds on a multiplayer server where every player runs the mod.
