Hi RAZD,
Not really a fair comparison, the kayaks design has a lot to do with the reason it flexes less (no deck on a canoe). I would bet the surface area for your kayak is less than that of the canoe, therefore which one would be less material? Wouldn't it be better to compare a wood canoe to an aluminum one? Comparing a kayak to a canoe is like comparing an open river barge to a submarine. "No sympathy for the devil; keep that in mind.

Hi Gullwind1
Yes.
This doesn't mean anything. Stresses are based on load and geometry, not the strength of the material. You can design to use the material strength to handle the stresses, whatever the material is. See reply to Theodoric (Message 210): wood along the grain is stronger than steel for the same weight.
Curiously, I quoted a Naval Architect with 40 years experience that says you are wrong - that is the purpose of the link I provided. Just claiming it is wrong is not you demonstrating that it is wrong.
Agreed, but what it does mean is that you can define the worst case based on the vessel geometry, and then design to it.
And that stress would still be less than the worst case design condition.
The shape of a wave is similar independent of cause, as it is governed by the physical constraints of water and gravity. A longer wavelength is more like flat water than a shorter wavelength for a vessel that has a shorter length than the wavelength. The purpose of mentioning the Tsunami wave is that a very long wavelength does not necessarily result in a high wave. What I said was quote: You need to show reference to a LOT of wind in the narrative before you can assume it is there.
Like the roaring 40's, which changes dramatically depending on weather conditions. Some days can be quite calm. In a steady state condition the swells would increase in wavelength in an open world wide sea.
But I'm NOT invoking magic, I am pointing out that you are making up stuff that isn't necessarily in the narrative. Without any credible information on the actual weather and sea conditions from the narrative, you would have to show a vessel cannot survive in the best conditions that meet the narrative information, otherwise you are creating potentially false conditions.
(A) how do you know this? (B) a larger wave, once the length of the vessel is exceeded, makes less of a problem, as the water surface relative to the vessel become flatter.
Yeah, but shipping companies make lots of poor choices with other peoples lives. So you are comparing the stability of a vessel with a larger length/beam ratio and likely a higher depth to beam ratio and possibly a higher CG to the purported ark in order to say that the ark would be unstable?
How so? A sea anchor would be a load in a different direction.
Why barrel rolls if the swells are a long wavelength exceeding the length of the vessel? Large but long drawn-out swells are not necessarily a stability problem. Again you need to show reference to a LOT of wind in the narrative before you can assume it is there.
You asked for it.
Correct, the stresses on a rooftop are likely considerably higher than sitting in the water for a year.
Sorry, but that is how actual design is done, by the equations, based on the calculated stresses and the material strengths. Vessels larger than the purported ark have been designed - you rode in one - so we are not talking about extrapolating off the end of known data.
And what were the weather wind and sea conditions?
Curiously, your opinion is not able to affect reality.
Are you? Without contradictory information you would need to assume the best case conditions from the information provided in the narrative. We can look at trees that are known to exist and see if they are long enough and large enough to provide material needed to build a vessel to the parameters given in the narrative. From what I can see, they exist such that a vessel could be constructed with wooden boat building technology.
Again, this is a design issue. The joints are not as neat as in a steel vessel, where material can be welded, but even in a steel vessel the joints are made with brackets to increase the strength and the joints compared to the middle of the beam. This is why traditional wooden vessels used knees.
Google 4 masted clippers, and you will find videos of one of these vessels in a storm with the bow snaking around in response to loads from the rigging.
The loads on that vessel would be due to the oars when it was taken out. Sitting there it did not have those loads.

Good. Me too. Funny how what I took from them is so different from you.
I meant the stresses wouldn't be along the grain, which seems to render your whole argument moot. The keel, for example, would have the grain running lengthwise (X-axis), while the stresses would primarily be up and down (z-axis).
But your argument is only valid along the grain, which does not always hold.
Sure.
But still affecting it, over and over and over...
Why? I'm assuming nothing more than the conditions that would be reasonably experienced in a real-world situation Do you have some reason to think that there would mysteriously be no wind anywhere in the world during the flood? I think you need to support your assertion that there was no wind more than I need to support the assumption that there would be some and it would cause swells just like it does today.
And would also increase in amplitude with no land mass to stop them. Waves (and swells) can build on each other as the frequencies match up.
You are making things up if you assert that somehow there was no wind. The bible doesn't mention that either.
No, what I'm doing is projecting the probable weather conditions that would be experienced in the conditions described by the narrative. I see no reason to assume that there was no wind anywhere on earth during the flood.
Because I've studied the effects that land has on weather and sea conditions, and what the lack of land would do to them. It wouldn't be millpond conditions all around the world, that's for sure.
That doesn't make the stress problem go away, it just means it won't be as bad as it could be. A vessel riding up and down 100 foot swells, even with a thousand or fifteen hundred feet between them is still subject to hogging and sagging.
Well, the food was good anyway.
No, I've never said the ark would be unstable. I said it would break up in rough seas.
A sea anchor would keep the bow into the wind and waves, thus causing greater hogging and sagging stress than if it was lying broadside to the waves, when it would be rolling back and forth.
You're assuming it would only experience long swells. I'm not.
Wind exists in the real world. Why would it not exist during the flood?
No, I asked how your kayak would react to being constantly flexed at the bow and stern, over and over for a year. You changed the comparison to being strapped to the top of your car. That's what I said wasn't a valid comparison.
But sitting in water while being flexed back and forth...?
But not by assuming that your can just add material to make it stronger by the same amount. After a certain point, the weight of the material limits how much extra stress it can take. And your calculations are still dependent on the strength along the grain of the wood.
No, but we are talking about scaling up from small wooden vessels to larger ones. You are assuming that increasing the size of the beam increases its strength by the same amount, regardless of the size. From what I remember, that isn't automatically the case.
I'm willing to be they weren't millpond calm.
No, but I'm basing my opinion on that reality.
Why not assume normal conditions based on what we know about weather? That's all I'm doing.
Sorry, I wasn't very clear. You keep talking about the strength of wood along the grain, so I was referring to finding a tree of sufficient size to carve a keel beam 450' long so that the grain would actually be in the same direction as the hogging and sagging stress.
None of which you can do with a wooden vessel. So you still have joints, flexing back and forth. Knees aren't as strong as welds.
Not arguing that the rigging caused stress. I'm disputing that the rigging was the main source of stress.
The oars caused too great a load on the ship? Seriously? I'd really like to see a source on that.

Hi Dirk, and welcome to the fray.
Curiously, it appears that most of those vessels survived for the length of service required of the ark, certainly for the 40 day period of rain\flood that would account for the major stresses on the vessel (with the remainder of the time sitting in calm water?). My point is that you cannot show that such a vessel as the purported ark cannot be built. The ark narrative does not provide much in terms of what the conditions were that needed to be survived, so it is difficult to gage the need for substantial structure. Was it a hurricane or just a rainstorm? Then you have the type of service in question: (1) all vessels with rigging on them (most of the ones on your list) are subject to high loads from the rigging. The loads are normally variable in direction and intensity, and this variation leads to working of these vessels much more than would occur in a non-rigged ship floating free. (2) vessels under tow are also subject to loads from being towed that mean the total loads are more than would occur in a non-towed ship floating free. (3) others have to have provisions for their intended use that jeopardize structure and storm survival (oar ports or gun ports in the sides). The main issues are joint construction and sealing of the vessel. Joint construction was not addressed in the narrative, IIRC, so you are going on assumption in that regard. The sealing was apparently done by tar, which was still used in the golden age of sail. Note that I am not arguing that the purported ark was actually built, just pointing out that you cannot assume that it couldn't be built without having a lot more information that is not available. IIRC there is no description of the internal structural elements at all.

Hi again Gullwind1,
My argument that wood is lighter than steel only applies along the grain. Now you are talking about sheer loads within the members, and this is a function of area vs stress. Again, you define the stress conditions, and then we can design to meet them.
How much and for how long? Define the stress and you can design to meet it. After the 40 days of rain don't we have a different survival condition, one that even a wounded ship could survive?
How do you know they are reasonable if you don't have any information about the actual conditions? Assumption? I didn't say there was no wind, I said that there was no real information on the wind, and that without information you are making stuff up to imply your case is stronger. I've seen heavy rain with no wind, so it is possible. http://www.genesis.net.au/~bible/kjv/genesis/ quote: Rising water. Some wind, but how strong not mentioned. No storm conditions mentioned other than rain.
Yes, and the loading would be significantly less with longer swells. The period of swells is related to the fetch of the wind (even little wind) so the swells could be very long but not very high. And without any information to derive a reasonable sea condition there is no rational to assume one with sever loading conditions. Enjoy.

That's what I've been talking about from the start.
Why? So you can dispute them and claim that without a specific description in the bible, we can't assume anything more than millpond conditions? I have reality, in which no wooden vessel larger than 400' has had any success whatsoever, and even then only limited.
The bible says they were in it for a year, but you don't seem to think there were any waves.
Not in reality. There would still be wind, swells and storms, unless you have some reason to think there wouldn't be?
Experience. I have sailed on the ocean, and I know the conditions one experiences there.
I'm not assuming constant gales. I'm simply assuming similar conditions to what is experienced today, with the removal of the canceling effect of the continents. Why is that not reasonable?
So you are advocating that god was magically interfering with the weather, preventing the normal conditions from being experienced. When you invoke magic, you can explain anything.
Not if they are building up over thousands of miles, with no continents to interfere.
Just experience and reality, but you don't seem to be interested in those. By the way, I'd still like to see some support for your assertion that the oars on the Tesseriaconteras were the source of its structural problems.

That sure is a lot. Much more than what Noah actually had to spend It would be neat to see them construct it and try to go about like noah did without using the modern technology we have to day. It would be like trying to re-contruct the Great Pyramid. Take this article for instance:
http://www.europa.com/~edge/pyramid.html If the Great pyramid was not there today but only written about, it too no doubt would be viewed as a "myth". Not being able to reconstruct something or imagine it's dimensions as unprobable certainly does not make it make believe by any stretch as witnessed by the Great pyramid. From the same article:
That's just some of the highlights of the article. If anything this gives the probablility of the Ark existing as much as the Great pyramids existance. The only difference being you can see the Great pyramid (seeing is believing for the skeptic) and only see what is written about the Ark.

Yeah, let's take it. Then let's drive a stake through its black evil heart, cremate it to the finest ash, sprinkle it with holy water, lock the cinders in a leaden casket, bury it under ten feet of concrete, and just pray that that's enough to stop the stupid from leaking out.

Wrong. The probability of the Great Pyramids having existed is 100%. The probability of the ark having existed is much less.
Some of the differences are that the Great Pyramids are mentioned in many historical documents; has been seen by many millions of people (thousands of whom are still alive) and is still there to see today. Whereas the ark was only mentioned in a book which is full of metaphorical parables. There are other differences, but I expect that pyramids are off-topic. Edited by Panda, : No reason given.

How in any way does it do that? Odds are just that, odds. We don't know the whole story. Just what knowledge the ancient Egyptians had, and why such knowledge was lost. Anymore than it was simply coincidence that these numbers correspond. People can read virtually anything into anything.

You could measure 4 millimeters of curvature in a 4000-year-old stone edge 230 meters long in aerial photos taken in the 1940's?

Maybe there is a point there ? If the Flood story is as wrong as that article maybe we're being unfair on poor old Noah. Maybe the real events were much more plausible, and it''s only the silly story in the Bible that causes us not to believe it.

There actually is some curvature/dishing/something non-planar in the faces of the Great Pyramid, a lot bigger than 4 mm. It can be seen in the shadowing of an aerial photograph alleged to be from the 1940s:
but it took careful surveying to measure it. Combined High Resolution Laser Scanning and Photogrammetrical Documentation of the
The middle is farther away than the outer edges. I hope the color-coding is obvious. Here Martin.au got hold of the raw laser data and posted some cross-sections: There was a very long discussion of the GP and its measurements and their possible meaning at talkrational.org.. Since the casing is mostly gone it's difficult to take what we can measure and convert it to measurements of the GP as-built. Febble posted a very good summary of the problems with the older surveys that seemed to indicate some special meanings of the as-built measurements here, although you might need to learn a lot of background to appreciate it fully. Bottom line: the available evidence clearly and unambiguously indicates that there are no meaningful numbers (year length, polar radius, etc.) encoded in the GP.
