How many decks did Genesis say Noah’s Ark should have?
Answer
Three decks
Genesis says Noah’s Ark should have three decks. Genesis 6:16 describes the vessel as having lower, second, and third levels, along with a door in its side and an opening or window near the top.
The three-level arrangement is part of the construction instructions given before the Flood. The text also divides the Ark’s interior into compartments, suggesting that it was intended to hold people, animals, and supplies in organized spaces.
The stated dimensions were 300 cubits long, 50 cubits wide, and 30 cubits high. Because the exact length of a biblical cubit is uncertain, modern estimates of the Ark’s size differ, but the three-deck description remains consistent in the Genesis wording.
Popular images often show a single large open boat or a highly detailed modern ship. Neither image should be treated as a precise blueprint: the Genesis account gives selected features rather than a complete engineering plan.
