Create: Ballast

by geonegames

Ballast Stones, a layerable block from the Create: Ballast addon, add weight to ship and airship builds in Create: Aeronautics.

NeoForgeClient and serverAll rights reserved1.21.1

What it does

Each Ballast Stone block gains mass with every layer added to it. Players right-click a stone to stack a layer, and can strip one away by holding shift while clicking with ballast or an empty hand. A shovel click also removes a layer. Dispensers can place layers, and remove them when loaded with a shovel.

The addon is meant for Create: Aeronautics, where ships and hot air balloons are hard to balance because the heaviest blocks in that mod weigh only 4 kpg. Ballast Stones let builders set weight distribution without placing many metal blocks across a hull. Create: Ballast requires Create: Aeronautics to be useful, and it targets NeoForge only.

The server and every player need the mod installed. Its builds cover 1.21.1 alone, with 0.1.1 as the latest NeoForge file, published on 2026-09-13. The mod was first published on 2026-05-03 and is released under All rights reserved, so it is not open source.

Key features

  1. Layerable ballast block

    Ballast Stones gain mass with each added layer, so builders can tune weight in small steps.

  2. Layer editing by hand

    Right-click stacks a layer, while a shift-held click with ballast or an empty hand strips one away.

  3. Shovel removal

    Right-clicking with a shovel removes a layer without needing to use the shift-click method.

  4. Dispenser support

    Dispensers add layers, and a shovel loaded into them removes layers automatically.

  5. Shapeless crafting

    Ballast Stones are crafted from seven cobblestones of any type, arranged in any pattern.

Use cases

Balancing airships

Builders adjust the center of mass on a ship or hot air balloon by placing stones where weight is needed.

Keeping hulls clean

Stones supply weight without covering a ship with metal blocks, which keeps the design intact.

Who it’s for: Builders working in Create: Aeronautics on NeoForge 1.21.1 who need extra weight on their ships or balloons.

Questions

Does Ballast Stones need Create: Aeronautics?

Yes. The addon is made for Create: Aeronautics and has little use without it.

Is the mod required on the server?

Yes. A server running it needs every connecting player to have it too.

Can a hopper automate layer removal?

A filtered hopper or pipe can pull stones from a dispenser without taking shovels. Filling a hopper's slots with shovels makes the stones drop on the ground instead.
