Valkyrien Skies
Valkyrien Skies 2 is currently in beta testing. The mod is stable enough for gameplay, but we've implemented less than 1% of all planned features!
Moving blocks. Scalable structures. Realistic physics. Small boats and massive ships. With Valkyrien Skies, even the sky is no longer the limit.

Buoyancy
Yes, exactly! If your ship is light enough, it will float on the water surface.

Full Collision System
Ships collide with each other, with the environment, players, and other entities. Valkyrien Skies seamlessly integrates with vanilla Minecraft mechanics.

Create Compatibility
Your favorite mechanisms from the Create mod can now be installed on moving platforms! This is just the first of many planned integrations with popular mods.
Important: Valkyrien Skies is a library mod, so you'll need to install an additional addon to use it in regular gameplay. If you're unsure what to choose, try Eureka!
