I did; I don't think it answers my question. What it shows,

The distribution of the equivalent stress obtained by the stress analysis is shown in Figure 3. Because the maximum stress was smaller than the allowable stress, the Ark could be said to have had safe structural performance.

Which means that it starts off in the position of a sailing ship that's been dismasted.

Well, no, because it wasn't meant to sail, so it isn't a sailing ship. They clearly mention this in the introduction:

quote:
... enable investigations of the practicality of the Ark as a drifting ship in high winds and waves.

So they evaluated that as a drifting ship, it could have navigated on waves as high as 30m. Note that this is using modern passenger ships criteria of what is 'navigable'.

Broaching to is when a ship turns side-on to the waves. In a storm, this was often fatal. That's why sails were required --- the ship had to be kept sailing in the direction of the wind, and if the sail or mast carried away, you were in trouble.

Ok. And so the danger is to overturn ? Isn't that covered in the 'overturning stability' section ?

If not, how do mastless ships (modern) deal with this ? Do they use their motors to align themselves continually, or can't you simply shape the boat so that it aligns itself naturally ?

Yes, modern mastless ships have to use their engines to be able to run before the wind. If they broach, then they roll and capsize, which is not specifically too good.

A number of possibilities present themselves.

1. The ark had masts. Now you have to add the labor of atually manning the masts and stearing to the labor of tending to all those animals.

2. The ark was a mastless barge. And it rolled. And sank.

3. The ark had engines. Not mentioned in scripture, but then again, it doesn't say that Noah didn't have engines.

4. The ark was an airship and floated above the waves. Or was actually a building and sat atop a mountain. Not really scripturally supported either.

5. The seas remained perfectly calm, despite 40 days and 40 nights of rainfall sufficient to cover the earth.

6. God magically kept the ark afloat, in which case why bother with all this real-world modeling and caluculating?

If you can come up with any others, I'd be interested to hear about it.

If you add in the fact that a wooden boat that large is going to buckle whenever it spans the trough between two waves, I'll go ahead and take the position that you can a priori say that that boat won't float.

Re: That boat won't float ... really ?
I still stand by my Robot Monkey hypothesis as the most parsimonious explanation of how the Ark worked. No creationist or biblical literalist has been able to refute it yet. However, I must admit that the Holodeck Thesis has a lot going for it as well. Any scientific theory that can include Jean Luc Picard as a mechanism is all right by me.

quote:
1. Noah did not actually have to do most of the labor building the Ark. Robot monkeys are easily programmed to do basic construction work.

2. Likewise gathering all the animals two by two. Robot monkeys equipped with jet packs could have traveled quickly around the globe to collect all necessary "kinds."

3. Robot monkeys don't need to sleep, so they can take care of all the animals around the clock.

4. Robot monkeys can also use their jet packs to fly out to all the floating vegetation mats to tend to insects too.

5. If the Ark were also equipped with a Matter-Antimatter Transmutation Fabricator (which the Robot Monkeys would also be able to build), then it would be easy to recycle waste matter back into fresh, nutritious food.

6. Radiation leakage from a broken Robot Monkey Atomic Power Pack could also have affected atomic decay rates around the globe, rendering all radiometric dating techniques invalid. This indicates to me that at least one Robot Monkey did not survive the whole voyage.

7. Robot Monkeys could also have a combined data storage capacity big enough to contain all the information they'd need to retrain young animals that were raised on the Ark to return to life in the wild.
