Foolish ideas
Lets put some numbers on this.
When you go down 33ft the pressure on you is 2 atmospheres. This is the pressure that you also need to prevent a 33ft rise inside the moon pool, and given the height of the ark that would be about right. Notice that 35 foot waves are small in the roaring 40's and 50's.
What this means is that to prevent a 33 ft rise inside the moonpool you need to double the amount of air in the ark at the same time that it is plunging into a wave nose first and bow down. Even a 16 ft rise means half again as much air. Where is all that air coming from while the hatches are closed to prevent incoming water?
To allow for ventilation those intake and outlet hatches need to operate in both 1 atmosphere and 2 atmosphere pressures or the animals do not get enough fresh air. They can't, so they won't: water will get in.
Assuming you could achieve rapid pressure changes of this scale, breathing during these pressure surges would be like breathing from a scuba tank and rapidly cycling between the surface and 33ft down ... bends anyone? Any air-filled containers (like lungs?) will be compressed to half their original volume and many animals are not be able to adjust to that kind of fluctuation.
And another result of massive pressure fluctuations to consider now is the ear popping you get, way more than going over mountains. This adds to disorientation and sea-sickness, and now you have another mess to clean up with water you can't pump out with any of your pump systems because they are operated by the water pressure and not able to overcome it. Maybe you need to add another hole to let the water out ....

More bad ideas
For the moment I've tossed the intake / exhaust idea, to beable to increase inside ark pressures,
So now the animals are suffocating from bad air.
make them bilge pumps to pump liquid wastes out the top of the ark
You have yet to show a mechanism for getting waste and excess water out of the ship. Your ram pumps waste 3 to 5 times as much water as they pump, meaning they are flooding the bilges not pumping them. They are only able to pump water from outside to upper levels, they cannot pump water from the bilge as they do not work that way (the energy to operate the pump comes from the wasted water). No other pump system proposed so far means the ship is assisted in sinking.
the other reason for the moon pool was to lessen stresses on a ship
What's added are new and different stresses on the structure to hold the moon pool together, keep it in place through the dynamic motions of the ship and to keep it from leaking.
And if you stick with the pressurizing pulses from the waves, then those stresses are added too, to the whole structure.
To be blunt: not one of these ideas results in a better design for the ark. Adding new fantasies on top of them to try to improve them only makes them even more ridiculous.

Re: More bad ideas
Your design for a moon pool is not what is used on large barges. The design of the ark (dimensions known) are not like those of a large barge either.
I have consistently told you that your idea of how a ram pump operates is wrong.
Let me spell that out: W R O N G.
It gets the energy to pump a little water from letting a lot of water flow through it - water that must be wasted to the bilge or it just doesn't work, water that is 3 to 5 times the volume pumped. This is like an open tap to flood the bilge. Rather than being able to pump the bilge it will fill it, rather easily.
Using the flow in the pumped portion of the ram pump flow to generate sufficient force for a suction pump wouldn't work either. The flow of the water over the suction intake has to be more than the flow pumped from a lower source to generate the suction. Assuming a 2:1 ratio based on heights let's add it up: 8 gallons water into the ark with 2 pumped out the roof by the ram and 6 into the bilge to power the ram; add back 1 gallon for the suction pump and you have 3 out from every 8 in, for a net gain of 5 gallons. In the bilge, sinking the ark.
Don't take my word for it - do some research, build a model and go for a trip. Take a life jacket and an epirb.

Re: More fantasies
JonF - I just don't think whatever sees the problems. Of course this is the same whatever that thinks there was self purifying water and most species survived the flood by swimming and clinging to floating masses of trees, so that they wouldn't take up precious room inside, so now he can fill that with all sorts of wondrous devices that are only limited by the vagaries of imagination.

Re: More good ideas!
How much experience do you have with boats, particularly boats in storms?
You are building a {rube goldberg \ perpetual motion} type scenario that just does not have enough power to do what you want it to. These systems will let more water in than they will pump out. Live with it and move on.

Re: More good ideas!
It would operate, but it would be incapable of generating sufficient head to pump overboard, to say nothing of powering a suction pump to suck out the bilge. It would be like a tap in the side: able to let water in.

Re: Ahhhh... so ...
They were covered with asbestos - why the dust was toxic even tho they said it was safe (riiight). Built just before the regs outlawing asbestos were enacted.
And yes, for some reason the engineers never envisaged a jet full of fuel being placed suddenly into the structure in their calculations. A major oversight that I'm sure will cost them their future life savings.
whatever bulwhah again.

Re: Well... how about back on topic eh?
spokes are good for tension loads
very bad for compression loads
the rim in contact with the road deforms slightly flatter forcing the rest of the rim to open a bit, countered by the pull of the spokes.
this is why hitting curbs is a bad idea, espescially at speed.
the best shape for the hull would be curved as then the compressive force of the water acts to force the seams between timbers together. think of an eggshell.
a flat surface on the otherhand will bend inward, increasing the distance to be covered and open the seams. This would also be the problem with the moonpool of course, especially just above the hull joint.

Re: More bad ideas
To say nothing of the bilge pumping system. Head pumps are bad enough for clogging, imagine the effect of 100 lbs per day of elephant dung ... per elephant.
His ideas might also be refined by a little experience on board a boat in a major storm (which would be insignificant to the deluge plus tectonic plate shifting tsunamis). In the roaring 40's would be good too.
Then add in the {keelsons on steroids} with the {nunchuk anchor stones}.

Re: sea anchor, sea anchor run
You obviously have no clue about:
  • how waves behave
  • the ability of water to mix
  • the effect of a world wide ocean on wave, wind and current patterns
  • the behavior of rocks on the ends of rope on a boat that is pitching and yawing in the waves
  • the lines of force needed to operate as a brake
  • the orientation of the surface of a sea anchor to best effect a braking force
  • global warming
  • tsunami
  • plate tectonics
  • etcetera
Repeating your arguments of admited ignorance is not making any progress. You could spend your time more effectively learning.
Whether or not you "care about" the orientation of the parachute sea anchor is irrelevant to the reality of the operation of the sea anchor, it is the result of testing many different methods, and is the best method available.
