Hans... it doesn't matter... the guy didn't build a boat.. he built a prop... just go to the link I posted and look at the building of... the outside "hull" is just planks of wood, nailed over 2x4s and insulation. Even if this thing had a bottom (which it doesn't), it would sink like a stone.
It's like going to the zoo and thinking you're in the jungle. The stone is made with concrete... the vines are plastic.
Yes, I noticed as much. Funny, but even the present contraption (buildt on a steel barge) wouldn't be seaworthy if built scaled X5.
BTW, do you know why Noah's Ark is usually depicted in the way quite well represented by this prop?
Because the Bible describes it like that? No, not really. The biblical description is quite vague. However, we have a picture of it!
... Or rather, we have a picture that has not only inspired later artists, but may very well have inspired whoever wrote the biblical legend: Queen Hatshepsut's big obelisk barge. Modern estimates have it as being about 90 meters long and 30 meters wide, and presumably, it transported two obelisks, placed side by side. However, ancient Egyptian artists did not depict things in perspective, so in the relief of the barge, it is shown with the obelisks laid end to end. So we have an image of what looks like a 180 meter ship, contemporary, not with Noah, but with the people who put the legend to paper (or, presumably, papyrus).
Of course, even this 90 meter ship was only for river transportation, carefully guided by oars and ropes from the shore. ..Which is a far cry from sailing in a planet-wide ocean.
