I want to know the answer to the following question:
What ship design contained a flat-bottomed hull?
All the background I'm provided with is that "Junks featured a square-ended bow and stern, a flat-bottomed hull or carvel-shaped hull with no keel or sternpost, and solid transverse bulkheads in the place of structural ribs found in Western vessels.". Is that enough to answer the question?
Answer: yes
