Noah's Ark replicas and derivatives

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, 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.

Full-scale
The Bible gives the length of the ark as 300 cubits. Various cubits were in use in antiquity, 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).
 * Johan's Ark in Dordrecht, Netherlands. 137 meters (450 ft) long and carried on a platform made up of 25 LASH barges, this is the only full-scale Ark interpretation that is actually floating and mobile.
 * Noah's Ark theme park at Ma Wan Island, Hong Kong. This interpretation is also 137 meters (450 ft) long.
 * Ark Encounter theme park located on a hill in Grant County, Kentucky, United States. It is 155 meters (510 ft) long.

Reduced-scale
