That's exactly what Johan Huibers has been doing over the last couple of decades. Construction of the huge vessel has been completed, and it was officially launched a few days ago. And Johan is henceforth awaiting, with confidence, the Apocalypse: first, the Mayan business, then maybe, with a bit of luck, a tidal wave or two. In any case, even creationists never know the surprises that God's got up his sleeve...
The Gallica website recently displayed here a small series of beautiful medieval images of the Biblical ark. As soon as we analyze these images, however, it becomes clear that artists in those days (the Middle Ages) must have had a terribly fuzzy conception of reality. Consider, for example, this presentation of the construction of the vessel:
Believers (like the crazy Dutchman) would probably tell me that images such as these must be taken merely as symbols, rather than realistic diagrams. Fair enough; nobody in his right mind would ever consider this artwork as realistic. But symbols are a convenient notion for trying to hide the obvious fact: namely, that there can be no plausible reality whatsoever behind the story of Noah.
Finally, the voyage went over well. And the following image suggests that, when they were about to return to dry land, many of the supplies stored down in the lower hull hadn't even been touched.
