There are some factors which are not considered in the several theories about Noah's ark. The ark wasn't a boat, it was an ark, simply a box. Even when today geologist swear that our continents have separated themselves from a sole huge ancient continent called Pangaea, the bible says something totally the contrary, that the smaller continents of today split from a sole huge continent just a few thousands years ago. If science is to study the known "deluge" event, then at least science must respect the testimonies of the bible in order to have a closer view of what happened according to the bible. But, if science will try to study Noah's ark as an event which happened thousands years ago in a world with split continents here and there, then the whole scientific study sucks and is a waste of time.
