In Genesis, what was the Ark’s height compared with its length: 30 cubits high and 300 cubits long?

In Genesis, the Ark was one-tenth as high as it was long: 30 cubits high compared with 300 cubits long. Genesis 6:15 also gives its width as 50 cubits.

This proportion describes a long, low vessel rather than a tall ship. The biblical text does not call the Ark a conventional sailing ship; it presents it as a vessel built to preserve life during the Flood. Genesis emphasizes compartments, waterproofing, and a door, while giving no detailed account of sails, oars, or a steering system.

Modern writers have compared the proportions with those of barges and other stable cargo vessels. Such comparisons can illustrate the dimensions, but they do not establish that the biblical Ark was built according to a surviving engineering plan.

The ratio is derived directly from the stated numbers. It is not dependent on deciding the exact length of a cubit, because the same unit appears in both measurements.
