Here is John Baumgardner's opening paragraph:
"Any serious model for the Genesis Flood must account for the massive tectonic changes evident in the geological record since the point in that record where metazoan fossils first appear. These tectonic changes include the complete replacement of the world’s ocean lithosphere, lateral displacements of continents by thousands of kilometres, significant vertical motions of the continental surfaces to allow deposition of thick and laterally extensive sediment sequences, and large local increases in crustal thickness to generate today’s high mountain ranges. Without a mechanism that can account for these major tectonic changes in a logical and consistent manner, any claims about understanding, much less modelling, the Flood cataclysm are hollow at best. The correct mechanism, on the other hand, will provide a framework into which the vast accumulation of detailed geological observations can be understood in a unified, coherent, and comprehensive manner. A major claim of this paper is that the mechanism of catastrophic plate tectonics, enabled by runaway subduction of negatively buoyant ocean lithosphere into the Earth’s mantle, does account for the main tectonic changes associated with the Flood and provides the best candidate framework currently available for integrating and understanding the vast store of geological observational data."

"Any serious model for the Genesis Flood" is and must be viewed with a great amount of speculation.
I have lived long enough to see "proof" disappear in the face of research, and opinions of major scientific folks radically change.
So, though we may disagree, it is more important that one also not "lock" into a specific view thinking that all is resolved. It is not.
"Major tectonic changes" did NOT have to occur at the time of the flood. That is a fact.
The changes could just as well have happened at the creation when God caused the land to appear by setting the boundaries of water.
There were volcanic eruptions because the smoke and dust kept the summers cool and allowed the winters do be cold enough that the Ice Age began at the end of the flood and built up for 500 years and then took 200 years to recede to today's ice cap geography. The ocean was thought to be about 86 degrees at the poles, hardly the boiling point that you are talking about since the flood left the earth about 70% water as it is today still.
You can't have it both ways.
Volcanologists know that one of the signs of an pending eruption is the local water temperature and often content changing.
If the North and South American continent, the African continent, India, Australia, and not to mention the Philippines and Antartica all shifted "thousands of kilometers" it would not have allowed the oceans to be merely a warm 85 degrees. That just is not feasible.
Beside, such activity would not have allowed the earth to replenish the growth as proven by Noah sending out birds in such a short time. Again, such is proof that the Teutonic plate shifting scheme may certainly be questioned.
Now you are questioning the seaworthiness of Noah's Ark. Based on the royal cubit, the Ark Encounter is 510 feet long, 51 feet high, and 85 feet wide. It had 3 decks inside and God commanded that the door be on the side: Genesis 6:16 (KJV) A window shalt thou make to the ark, and in a cubit shalt thou finish it above; and the door of the ark shalt thou set in the side thereof; [with] lower, second, and third [stories] shalt thou make it.
Now Noah was a great man. Not only was he a ship-builder of a very, very large ship, but he also had to have been a naval engineer. For a discussion of naval architecture, began looking at this video at the 12:45 mark, about half way:
How Could Noah’s Ark Survive the Storm?
Ok, let's get this straight.
1) I have no contest with the presentation of the Scriptures concerning the Ark, nor that God preserved as only God can.
2) I do know enough about wood to know that no building constructed to keep water out is capable of withstanding the enormous natural pressures the movement of Teutonic plates would have created. That is just fact. The modeling of the video does not compare to what violence such would have been.
3) The occupants in the Ark were not "strapped down." There were no seat belts, shoulder harness, or restraints. The violence created by Teutonic plate shifting would far exceed the ability of any life to survive on the ark. That has been completely validated by such tragedies as Nascar racers running into a solid wall at 130 MPH. Water is not forgiving, and even a minor tsunami displaces and causes havoc.
4) There is no account of wind along with rain at the time of the flood, but one does not have such upheaval as suggested in your post without tornadoes, and hurricane force winds. Having been through both, I can assure you that wooden structures no matter how well engineered cannot withstand such forces for 40 days.
Ok, I think by now you get the point.
All really I suppose you are encouraged to do is keep all things as pliable and speculative EXCEPT what is specifically related in the Scriptures. Don't conform your thinking without a healthy dose of continued speculation, because often doing so removes the thinking processes.
