Well, in a world that was covered in turbulent water, the notion of “destination” would be more than just abstract, so “navigable” would of necessity take a backseat to stability, wouldn’t you think?
God knew the outcome of the chaotic forces at work, and the Ark came to rest where it was intended. There was no more navigation involved than throwing a message in a bottle into the Atlantic on the Outer Banks of North Carolina and it ending up in County Cork, Ireland.
That’s essentially what I was saying. Navigation played no part, and they were in God’s hands.
