Numerous interpretations of Noah's Ark have been built and proposed. Some were intended to be replicas, as close as possible to the Biblical Ark, the builders assuming that such a boat did exist and that it is not a mythological vessel. Others are looser derivatives which were inspired by the idea. The Biblical description of the Ark is brief, beyond the basic measures of length, height and width,[1] and the exact design of any "replica" must largely be a matter of conjecture. Some interpret the Ark as simply a chest-like structure with rectangular sides; other reconstructions (like Ark Encounter) give it a rounded bow and stern.
The Bible gives the length of the ark as 300 cubits. Various cubits were in use in antiquity,[2] but to be considered "full-scale", an Ark replica would have to be somewhere in the range from about 135 to upward of 150 meters long (ca. 440 to 500+ feet).
