In Genesis 6:15, God instructed Noah to build an ark that was 300 cubits long, 50 cubits wide, and 30 cubits high. This is a ratio of 30 to 5 to 3 (length to breadth to height).
Until about 1858, the ark was the largest floating ship ever created.
In terms that we understand better, the ark was about 450 feet long, 75 feet wide, and 45 feet high.
In 1844, a man named Isambard K. Brunnel built his giant ship, the Great Britain. He used almost the exact ratio of the ark—30:5:3.
As it turns out, these dimensions are the perfect ratio for a huge boat built for seaworthiness and not for speed. Obviously the ark was not built for speed, since it had nowhere to go!
What is more, shipbuilders during World War II used that 30:5:3 ratio to build a boat that came to be known as “the ugly duckling”—a barge-like boat built to carry tremendous amounts of cargo, and one that had the same ratio as the ark.
How did Noah know the perfect seagoing ratio to use in building the ark? Brunnel and others like him had many generations of shipbuilding knowledge to use, but Noah’s literally was the first of its kind. Where did he get such information? From the Master Builder!
