Could some people take a look at A Series of Logistical Feasibility Studies of Noah's Ark and comment on it here?
Thank you...
Thank you...

His calculations are off:I. FEASIBILTY STUDY #1. Could eight humans have built the ark in 100 years, the actual time that the Bible seems to allocate to Noah to build the Ark?
[...]
The outer surface area of the ark was 114,750 square feet. My basis for this figure is as follows: The port and starboard sides of the vessel were 450 feet by 45 feet (20, 250 square feet each) The roof and bottom of the vessel were 450 feet by 75 feet (33,750 square feet each) The fore and aft sections of the vessel were 75 feet by 45 feet (3, 375 squre feet each) To give you a general idea of how much wood this is, a wooden plank 12 inches wide, 114, 750 feet long would be 21.7 miles in length.
If we assume three decks internally, as recorded on the Bible, plus the floor covering the water (See feasibilty study below) , that would add another 135,000 square feet.(if calculated two dimensionally)
Factors impossible to calculate would be the amount of wood necessary for transverse or longitudinal beams, the keel, stockpens, support beams, storage areas, and bulkheads, as these specifics are not discussed in the Bible.
He is so badly offbase here it's not even funny.Many naval architectural engineers have concluded, though, that a wooden ship built with no metal structural supports and only pitch "gluing" it together could be no longer than 300 feet and still maintain structural integrity on the high seas. Did Noah find a way around this limitation?
Successful timber ships over 67 metres long, carrying heavy loads, and built before the 19th century (Egyptian obelisk barges, Greek warships, Chinese baochuan), used the following technology:Genesis 6:
14 Make for yourself an ark of cypress wood. Make rooms in the ark, and cover it with pitch inside and out.
This 'august boat' was around 63 metres long, and 20 metres wide (207 feet long, 60 feet wide), built using Early Bronze Age technology.'I inspected the erection of two obelisks ////// built the august boat of 120 cubits in its length, 40 cubits in its width, in order to transport these obelisks. (They) came in peace, safety and prosperity, and landed at Karnak ////// of the city.'
Tomb inscription of Aneni, official under Pharoah Tuthmos I, 1500s BC, translation in JH Breasted, 'Ancient Records of Egypt', Part Two, 326 & 328, 1906
* He concludes that it would have been possible to take '1, 402 animals, not counting arachnids and insects', with all animals being fed, watered, and cared forII. FEASIBILITY STUDY #2: How many animals could realistically be supported on the ark for 150 days without resupply?
This question is irrelevant.III. FEASIBILTY STUDY #3, A HYPOTHETICAL SCENARIO: If only humans were on Noah's ark, how many could it realistically carry and provide food and water for 150 days, the time the ark was alleged to be adrift?

I'm not that fussed about it. Either way Noah had plenty of time.Turgonian wrote:Fortigurn, thank you very much for your replies!
What do you think of the 100 / 120 years?

I suggest you use a more academic source next time. One which is actualy relevant to the topic at hand.PEGASUS_VOYAGER RESPONSE: My calculations are based on a reference in the King James Version of the Bible, of which my parents gave me a copy my first year in the Army, 1980.
I have no problems with space, because I believe in a local flood. Even the feasible number of animals you finally arrived at is more than enough, in my view.Also, don't you think you're "shooting yourself in the foot" by saying it was shorter? You're already strapped for space in this thing as it is.
Please don't put words in my mouth. I was doing no such thing. I was simply correcting an error.Of course, your intent was to subtly suggest my feasibility study is flawed by implying I don't know the true definition of a cubit.
Yes, they will say that the cubit length differed over the history of Israel. I have referred to that length which is proximate with the writing of the Genesis narrative. That is the only relevant length.If you consult most references, they will say that a cubit will range from 17 to 21.88 inches.
No I am not. There is no necessity for it to have been of one piece.PEGASUS_VOYAGER RESPONSE: In other words, you're saying that Noah and his family sewed together a roof the size of a circus tent?
Even canvas holds up very well in torrential downpours (I refer you to the traditional use of canvas in the history of sailing, as well as to the huge meeting tents which were used in the 19th century revival meetings).Are you really serious when you imply that this thing could hold up in a torrential downpour?
I was not attempting to discredit the entire study with a trivial point. I said nothing about this one point discrediting the entire study. My point in raising the roof issue was to correct your assessment of the amount of timber required. I know you acknowledged the project was feasible given a century or more to do it, but I would prefer an accurate presentation of the account rather than an inaccurate one.But your point is irrelevant. I conceded that the project was feasible and "do-able" even if there was a wooden roof. So why even bring up the roof issue? You are "sound-biting" me, setting up a straw-man that doesn't exist, and attacking it. I thought Christians were supposed to be totally honest in everything. Obviously not in apologetics. Once again, you wish to discredit the entire study with a trivial point. If the roof being made of wood made the project improbable, your point would be relevant, but to reiterate, I conceded that the project was feasible given a century or more to do it.
I am neither an evangelical nor a fundamentalist, but this is beside the point. It is not taking the Bible literally to say that only Noah (or only his family), built the entire Ark by themselves. The Bible says no such thing.PEGASUS_VOYAGER RESPONSE: To echo mwc's response, because the Bible doesn't say otherwise. Evangelicals/fundamentalists take the Bibe literally when it suits them, then put words in the authors mouths and read into it what isn't there when it's necessary to support their conclusions.
I think this is a little disingenuous. For what purpose did you raise the authority of these 'nautical engineers' if not to cast doubt on the possibility of the Ark being of the dimensions and materials described in the Bible? If you're happy with that possibility, great, let's move on. But let's hear no more about unnamed 'nautical engineers' who say such a vessel could not have been built.PEGASUS_VOYAGER RESPONSE: First of all, I am not off-base. I did not myself say that building a ship longer than 300 feet completely out of wood and pitch was impossible, only that nautical engineers had. If they're wrong, fine. If you recall, I asked: "Did Noah overcome this limitation?" Did I say "It would be impossible to overcome this limitation"? No, I did not.
Clearly you viewed this limitation as fact.Did Noah find a way around this limitation?
Are you seriously suggesting that when Noah was told to build an Ark out of wood and pitch, he was told to do so without anything else, including tools? This is not an honest way to read the text.Noah was told to build the boat out of gopher wood and pitch. Did the Bible say "nails"? No, it did not. Did the Bible indicate any other construction material other than wood and pitch? No, it did not.
Firstly, the similarly scaled Egyptian ships to which I referred used no nails or spikes at all. They used mortise and tenon joins (which I made very clear in my post). That aside, I also made the point that at this time in Mesopotamia copper tools, nails, and drill bits were already in use, demonstrating that they could have been used to build the Ark (though they were not necessary).Also, every ship you mentioned that was close to equivalent in size to the ark, especially the Chinese treasure ships, required nails and/or spikes to fasten the wood.
So what? We're not talking about a ship desgined identically to a baochuan.Also, the Chinese vessels had to be launced before the upper decks were completed.
Why is it 'doubtful'?Additionally, these ships were designed by men who were extremely learned in this field of endeavor. It is doubtful that Noah had this expertise, and also that he had the manpower to do it.
Argument from silence.The Bible makes no mention of a brigade of "hired hands" to build this thing.
Not only have I not suggested it, I have suggested the opposite.I conceded that eight people could build a wooden building essentially in a century, but a ship equivalent in compexity to these ships you mentioned? Don't even embarass yourself by suggesting it.
Argument from silence.And yes, I know the Bible doesn't say that he didn't have help, but neither does it say that he did have it.
Firstly, I'm not an evangelical. Secondly, if you had done any serious research on this issue you would find that the first extra-Biblical reference to the flood being local is found in the Jewish Talmud (1st-5th centuries AD), and that standard Christian commentaries from at leass the 17th century were interpreting the flood as local.PEGASUS_VOYAGER RESPONSE: Okayyyyyyyy, when did the evangelicals "shift gears, fall-back and regroup" to the local flood scenario? I was addressing the global flood scenario. Obviously, I missed a memo or didn't read the bulletin board. Also, is it possible you finally woke up and realized that the global flood idea "won't hold water"?(sorry, couldn't resist that)
It appeared to me that your calculations of the average food intake of each animal included the intake of these animals. I'm sorry if I misunderstood you and you did not in fact include the food intake of these animals when calculating the average food intake of the animals.PEGASUS_VOYAGER RESPONSE: This answer is either rooted in a misunderstanding or out-and-out dishonesty. I never included those animals in my calculations for food, ony mentioned them as "FYI". I suppose by default you could say I included them since they took up space that could have been used for food, but I did not "factor in" their actual daily food intake.
Yes, I agree that your assessment provides a challenge for the global flood scenario. I don't hold to that view, so it's no problem for me.And once again, I was addressing the global flood scenario, which many, many Christians still embrace, so obviously hippopotomi and elephants would have to go along, since I believe it is a safe bet they couldn't tread water for 150 days.
The stated purpose of your study was to discuss whether or not the building of the Ark was feasible. This question about how many humans could have fitted into it is irrelevant to that purpose. As you said, it is only relevant to the question of whether or not 'all humanity could have fit on the boat'.PEGASUS_VOYAGER RESPONSE: Ultimately, it is not. Once again, you are "sound-biting" me. I indicated at the end of the study my purpose for doing it was to address a preacher's contention that all humanity could have fit on the boat. I also did this hypothetical study to reveal that the ark was not "larger than life", or some wooden "bottomless pit".
I agree.DISCUSSION: It is a common belief amongst Christians that Noah was given 120 years to build the ark, based on Genesis 6: 3. This is false.
This is totally bizarre. I said nothing about you being wrong. I actually agree with you. I don't care what people make of this point. You have not 'exploded a myth' or 'exposed an error that has existed for centuries that even the most learned of theologians missed'.PEGASUS_VOYAGER RESPONSE: In other words, you are conceding that I could be right, but your hubris won't allow you to admit that an apostate skeptic "exploded a myth" and exposed an error that as existed for centuries , that even the most learned of theologians missed.
I most certainly would not. I wouldn't have paid any attention at all. I have no time whatever for Kent Hovind.If Kent Hovind had caught this, you would have hailed him as a "brilliant Bible scholar"
It's disappointing when people don't read posts. I'll deal with this briefly:I see 3rd century BC. I see 200 BC (better). I see 15th century (presumably AD). Now, which of these designs are from 23rd century BCE? Which of these designs are for deep water with absolutely zero control? Just to be tossed about like a cork on the roughest oceans ever seen? Even if the boat survives what are the odds the cargo is dashed to bits on the interior? Zero? Good guess and very accurate. All the ships mentioned where designed to be controlled. All the ships mentioned would sink in rough waters. Why not just mention a modern carrier or something as long as you're comparing apples to oranges (which would also sink in the conditions of the biblical flood). Just because they're made of wood doesn't mean they're the same. I'm also sure that you're aware of the modern wooden ship that was built that leaked like crazy and had to be crossed braced with metal just to be structurally sound.
Find a 23rd century BCE (or older) barge of this size designed for use on the high seas and get back to us.
* The OP that started all this was seeking to address the question 'Was the Ark possible?', and chose to set the feasibility study in the context of a global flood - I said 'Yes', in the contex of a local flood, but the replies made to my post did not actually take this into accountmwc wrote:Actually, this was understood, but you're the one that took a posting a changed the parameters of the debate. The OP that started all this was about a global flood. It's not my fault you felt this alteration should be respected when you failed to respect the OP. The bible says it's a global flood. You say it's a local flood. I say there's no flood. Now it's just a matter of scale, isn't it?
* If you had read my original post, as well as my succeeding post, you would have seen why I raised the other exampoles of large scale timber ships - Pegasus Voyager had cited unidentified 'naval architectural engineers' as giving their professional opinion that a wooden ship with no metal structural supports could not be built larger than 300 feet in lengthSo, they are meaningless? You are trying to say that boats this large are possible and therefore, perhaps, Noah's boat was possible.
A barge is exactly what I argued for in my posts. I did not argue for a polyreme (please read my posts).However, an ark is normally accepted as a box like object, so Noah was probably in a barge (not a polyreme either).
This ignores the data I provided:All the evidence from the time period (c2300BCE) shows no boats like the ones you describe. Unless Noah was 2000 years ahead of everyone in naval engineering then show all the example ships you like but he would have built ships of his own day like it or not.
* I acknowledged it was built in the 16th century BC, but I pointed out that it was built with the same nautical technology and design which had been used since the Early Bronze Age - the ship was simply a scaled up version of previous vesselsYes, you did show this. It was a nice picture too. It was also too late as I recall. Also a ship not built for the type of flood we were discussing and until we're on the same page on that this one will have to put on the sideline.
* The 'earth' was Mesopotamia in this historical contextThe bible mentions 40 days of rain, the ground waters bursting forth, it makes no mention of the Mesopotamian flood basin but it does mention snuffing out the all life (human and animal) on the face of the earth. It mentions the waters covering the earth for about one year before the boat comes to rest at the top of a mountain (hard to do in a flood basin). The whole earth being covered by water would produce the roughest waters ever seen.
* I am assuming you know a lot more about the hydrology of the 2,900 BC flood than I do, so please provide your sources (this idea that 40 days of non-stop rain would cause a flood with rough waves is particularly intriguing)Even if it was a local flood, if it rained non-stop for 40 days in a local area this would produce a horrific scene in that area. It would be rough. Your cited boats would sink. All of them. They would be swept away and dashed into something, or something would smash into them causing major damage. That's what happens when a flood comes along in a flood basin. You aren't "gently" lifted into the air as the water comes along. Your scenario causes major issues with the initial rush of debris that will destroy your ship.
This is a mischaracterization of the argument. The question at issue was whether or not civilizations contemporary with Noah's had the technology necessary to build ships on the scale of the Ark. The answer to that is yes.Pegasus Voyager wrote:Hey, I thought of a good argument to counter this "Other civilizations had big boats, why not Noah?" stuff. If God instructed Noah to build a spacecraft to house all the animals, would the fact that space travel is feasible in the 21st century make space travel feasible in Noah's century?
This is yet more evidence that my posts are not being read. I was not the one who referred to you as 'panicky'. That was Turgonian. I referred to you as 'angry' because your post sounded angry. I apologise if I misread you.Also, did you see all the "red herring" arguments this fortigurn guy was using? Calling me "panicky" because I responded so quickly to his critique. and "angry".
I didn't see any screaming being done, nor a 'mini-thesis'. I simply pointed out a few errors in your study. As it happens I clicked on that thread by chance, no one alerted me to it, and I responded to it when I read it simply because I had the time to do so. You appear to be overdramatizing the situation for polemic purpoes.Talk about hypocritical! Who's being "panicky" here realistically? Within a matter of hours after I posted my feasibility study, turgonian goes running willy-nilly to "god and science" screaming "DANGER WILL ROBINSON", and within a 24 hour period, his friend fortigurn spits out practically a mini-thesis to attack my study. And they call me "panicky"???Please!
No I didn't. What do you mean by this?Also, did you notice how "canned" and "scripted" turgonian's conversation with fortigurn apeared to be?
I saw no 'talk about anger management', nor any evidence that anger was being treated as 'aberrant or deviant'. Which posts were you reading?Also, in the immortal words of "Emily Latella"(Gilda Radner), "What's all this talk about anger manglement?? Pretty soon they'll want to shred depression!" Even if I was angry, which Im not, why is it treated as something aberrant or deviant if you are, especially in the Christian community.
I certainly agree.Anger is a perfectly healthy emotion, as long as it's controlled.
I'm not aware that I was jumping through any hoops. I saw something which interested me, and I responded. I'm actually flattered you took the time to review my reply (even though you didn't read it properly).Additionally, why is this guy fortigurn jumping through hoops over this? Was my study that big of a deal to these guys? Actually, I'm kind of flattered!
I suggest your search technique may be at fault. Try here, here, here, here, and here. This is a matter of historical record.mwc wrote:I did a quick search for this "august boat" and came up empty handed. I'll try again later when I have a bit more time.
They are not too late, because they use the same Egyptian ship building technology and techniques which was used over 1,000 years earlier, simply on a larger scale. Egyptian ships dating to the 1st dynasty (the Abydos ships of 2,950-2,775 BC, found in 1991), used exactly the same building techniques. The Solar Barque to which you linked is certainly not a case of comparing apples to apples, because it is not a freight barge but a funerary artefact. It is undoubtedly seaworthy, but it is clearly not intended to carry freight (it was probably designed for a sarcophagus, but nothing in the way of freight).However, both of these Egyptian boats are from roughly 1000 years too late (You should be considering something more like this: http://www.pbs.org/wgbh/nova/egypt/explore/boat.html which is far closer to the time period we're discussing and keeping in mind apples to apples it is also Egyptian like your example).
I'm wondering how this is relevant.From the image you posted it appears the cargo is placed upon the deck as opposed to internally if we take the image literally. They don't appear to be designed for anything other than river work.
What do they need to be good for? They were able to carry very heavy loads, certain of them were designed to drift unguided (without a helmsman or rudder), they could travel 60-70 kilometres a day with a load of several hundred tons, and they kept the water out. What else do you want?So beyond being able to carry a very heavy capacity on the deck what are they good for in a flood?
I can certainly answer these questions. They were very good. We have multiple epigraphical and papyrological sources which illustrate their success (not to mention the many obelisks themselves which these ships carried). These ships were used on a regular basis, year in, year out. Records have been found warning of the various dangers encountered in the river channels at different times of the year (in particular the danger of running aground in the summer season, when the rivers were low).How GOOD were these ships? Your image cannot answer this nor can your argument. Did they all work as designed 100% of the time or did 99% of them sink? Is that why the Aneni was so proud? He actually succeeded where others had failed?
Large wooden freight barges capable of moving heavy loads by virtue of displacement rather than buoyancy are found as early as the pre-dynastic era, with rock carvings and pottery illustrations displaying vessels of 200 and even 275 feet long.The feature is seen repeatedly on representations of other early Egyptian boats, and indicates 'accepted practice': the correct way to build and to portray a boat incorporated transverse lashing of major components.
By the fifth millennium BC, some boats were able to move large loads because they relied on displacement rather than simple buoyancy.
[...]
It can be suggested that the practices by which the transition was accomplished were rapidly standardised and can be traced through Egyptian boat-building for more than a thousand years. Examination of woodworking and standard boat-building techniques in the fourth and third millennia supports this hypothesis.
[...]
It is possible to examine the development of woodworking skills through tools, artefacts and features in tombs at several sites. By the mid-fourth millennium, evidence for sophisticated woodworking exists, and specialised carpenters had probably become a part of ordinary life in regional centres such asMaadi,Nagada orNekhen.
[...]
Grave enclosures in the Predynastic Naga-ed-Dêr cemetery (Lythgoe & Dunham 1965; phase dates in Savage 1998) demonstrate an increased standardisation and complexity of woodworking technology.
[...]
Knowledge and control of raw materials, production and design are reflected in technological standardisation visible by the third phase of Nagd-ed-Dêr burials [pre-dynastic era] when a limited range of techniques was repeatedly used to join individual planks of uniform thickness and width with lengths of 2m or more (Lythgoe & Dunham 1965: xiv-xv, 202-5).
[...]
It was startling to realise that the strap shows the same weave and
approximately the same dimensions as similar remains from Lisht planks created more than a thousand years later.
[...]
Examination of the details of hull construction over a period of 1200 years indicates regularities in design, plank shape, plank fastenings and even the dimensions of individual components.
One explanation for the enduring tradition could be the establishment of communities of specialists with an extensive apprenticeship programme that maintained group practice over a very long period.

I am amazed that 'His is the only mention of the "august boat"' you could find. This is not about 'one difficult to locate inscription' (you appear to be overlooking the Hatshepsut barge, the details of which I provided for you, including the epigraphical evidence, and which was even larger than this 'august boat'), this is about a nautical culture which left copious records of its technology, designs, and achievements. Egyptian inscriptions detailing their nautical technology are legion. We have books and books of them, and the evidence for the obelisk barges in particular is abundant. Herodotus notes that they were still being used in his own day, and marvelled at the huge loads they were able to carry.His is the only mention of the "august boat" I could find so your claim that "there was no difficulty in constructing them with this technology when the need arose" is unfounded. That's okay if that's your assertion. Perhaps it's even true but one difficult to locate inscription seems like hardly enough evidence on which to base such a claim (and it seems everyone simply copies this same bit over and over unfortunately...so my search for something more concrete continues).
Not only do we know that obelisks made it far outside Egypt, but we know that the ship building techniques the Egyptians used had first arisen in Mesopotamia before travelling West to Egypt. They were using techniques which had been used since around 4,000 BC in Mesopotamia. In fact they were still trailing behind the Mesopotamian nautical technology in Hatshepsut's reign, since the Mesopotamian ship building technology had by this time been using copper nails and drill bits for around 1,500 years (before 3,000 BC in fact).They must have gotten better as time went on since we know obelisks made it far outside of Egypt. I have no qualms with that.
I believe I've explained why it does. That 1,500 BC boat was built using exactly the same technology and construction techniques which had been available and used since the Early Bronze Age. The only difference is that it was a scaled up version of the commonly used Early Bronze Age design.However, we are talking about Noah and not the Egyptians and so this path only takes us so far. I concede that the Egyptians may have built a really fantastic boat around 1500 BCE but that has no bearing on Noah of the ~23rd century BCE.
You appear not to have read my post. I did not assert that any given design can simply be scaled up. I am aware of the law of diminishing returns. You are not actually addressing what I wrote. I pointed out that the Early Bronze Age ship building techniques of the Egyptians were still being used by the Egyptians in the Middle Bronze Age. I pointed out that they were being used in the Middle Bronze Age to build ships far larger than had been built by the Egyptians in the Early Bronze Age.As for this statement "Proven design techniques were simply taken and scaled up as required." This rarely works in the real world. I'm not an engineer but I've had enough of them talk over my head to know that materials, especially wood, can't just be "scaled up" otherwise we'd have wooden sky scrapers. We don't. Wood fails structurally at a given point. It's a fact. Make it thicker and you not only add weight but you lose your internal cargo space. There's a point of diminishing returns. I'm sorry I'm not the one to discuss the finer details of this with as it's way out of my area of knowledge. However, the broad stroke, you can't simply take something that works on the small scale and make it bigger "as required," is a factual statement. Sometimes it works and sometimes it doesn't (with something as complex as a ship with all it's various stresses I'd imagine it fails more often than not...I'd ask a nautical engineer if I knew one).
