This is a Chinese Junk, an ancient ship design that is still used today.
I built this ship because I accepted a small challenge.

The ship is part of my ship bundle which can be found here:

Minecraft version: 1.12.2
(newer versions like 1.13.2 work as well)

Due to the scale of the ship, it is doable to recreate it in survival. There is always room enough to walk around the inside of the ships I build but it can be cramped.
The ship has been made using the vanilla textures.
Renders are made with the Chunky program.
