In Genesis 6:16 God told Noah to make the Ark “with lower, second, and third decks.” For efficient use of space, Noah could have added a couple of half-floors that did not extend across the entire width of the ship. These would be perfect for storage, animal housing, and easy movement on ladders and staircases between decks.
God also told Noah to “make rooms [nests] in the ark” (Genesis 6:14). These rooms or nests would simply be stalls and cages for the animals. Noah could have put the animals on the three decks, and then moved between the decks on the mezzanine levels. They could also hold tanks and pipes to distribute food, water, and waste.
The Ark had a very striking shape—its hull was six times longer than its width. A major 1993 scientific study found that these proportions perfectly balance the conflicting demands of stability, comfort, and strength.
This study, headed by secular engineers at a world-class ship research center in South Korea, called KRISO, compared different hull proportions. No shape significantly outperformed the 4,300-year-old biblical design. Many other proportions rendered the vessel dangerously unstable, uncomfortable, or prone to breakup.
In fact, the Ark has the same proportions as a modern cargo ship. Clearly, the Savior of the human race knew what He was doing.
How did Noah build the ark? This issue explains how Noah had technology to build a massive Ark and how eight people could care for so many animals.
