    have you noticed a lot of recent threads where a 'new member' OP makes some curious statement or wacky plan, that excites lots of time and comment, but the OP never appears again ?

    I think its a bunch of NA's who are rolling around the floor laughing at all the wasted time and effort put into 'sorting out' the facts.

    Either that, or its a government plot to keep boatbuilders off the water.

    There are two ways to approach this.

    1. With resources to actualize it, get help and plan to be the first to market. Get the rewards of being first knowing that others will copy in time.

    2. Hire a naval architect and other experts you need based on their reputation and have them sign a nondisclosure agreement.

    c

    Could you direct me to an example, Please.

    Plus my concept does not use a caraavan.

    Thank you, positive feedback.

    I do not know a lot of nautical terms, but I would like to know how to work out tonnage to flotation. In my words how much floatation is required for a particulat wieght load.

    It was interesting to see the the size dimensions for Noah's Ark are the same dimension used in todays ships, or in Marine Arcitecture.

    Is it the lenght is 6 times the height and the width is ??? the height. I don't mind if we have to build this thing in cubits?

    The black polythene type material they use in oyster barges now, is that feasable for a houseboat flotation section?

    I already have concepts on drive, steering, transport and mechanical applications, adn I have not onsidered any electricla fittings, only mechanical

    The power source is the simplest of the concept.

    To present a concept for patent it requires poand and details. I cannot work out the details, the nauticla engineering or the statutory regulations that would apply until I talk to those that know these things.

    I am beginnign to think that I should just throw it out 'There' and have this forumm to show that it wasmy idea when the builders make their millions.

    I mean, I am 75, and all I really want is only 5 cents more than I can spend.

    That's an interesting statement.

    What *are* the dimensions of Noah's Ark and how do you know? Perhaps you should read threads by member goodwilltoall, you might find you have a lot in common.

    As for your specific question, google 'Archimedes'..... and keep in mind that 1 tonne of water is 1 cubic metre of volume.

    I thought for an outback writer, an "ark" would be a crow call, but, I'm wrong again.

    Actually not a bad day today, compared with yesterday - at least the temperature got to double figures. But the epoxy needs another 24 hours minimum to cure so I'm trying to avoid going anywhere near that sub-assembly.

    Working on the anchor winch instead. The man who sold it to me said it was stiff. Sure it is. He didn't mention that it appears to be an amalgamation of 2, possibly 3 anchor winches with the bits forced together regardless of actual fit.

    Oh well, it *was* cheap and I do have a machine shop. Tomorrow I get to ream bushings and re-cut tapers on shafts. All this because I needed the bench space for the new eBay purchased surface grinder I'm pulling apart.....

    Do not worry too much about the scource of this information, as it ws given by a professional, and not as a religious sermon.

    Don't shoot the messenger!!!!!

    Noah’s Ark and Naval Architecture

    The Ark’s Design
    Good Seakeeping
    Safe and Comfortable

    Noah’s Ark and Naval Architecture

    FOR more than 40 years, I have worked as a naval architect and marine engineer. My work has involved designing vessels of various shapes and sizes, along with the mechanical and other systems that propel them. In 1963, while I was living in British Columbia, Canada, one of Jehovah’s Witnesses showed me that the Bible book of Genesis describes Noah’s ark as a long box, or chest. This description intrigued me, and I decided to look into it further.

    The Genesis account shows that God determined to cleanse the earth of wickedness by deluging the planet with water. He told Noah to construct an ark in order to preserve himself, his family, and representatives of the animal world through this great Flood. God told Noah to make the ark 300 cubits long, 50 cubits wide, and 30 cubits high. (Genesis 6:15) According to one conservative estimate, this would make the ark about 438 feet [134 m] long, 73 feet [22 m] wide, and 44 feet [13 m] high.* It thus had a gross volume of some 1,400,000 cubic feet [40,000 cu m].

    The Ark’s Design

    The ark was constructed with three decks, which gave it added strength and provided a total floor space of about 96,000 square feet [8,900 sq m]. It was built of resinous—and thus water-resistant—wood, possibly cypress, and was sealed inside and outside with tar. (Genesis 6:14-16) We are not told how Noah fastened the timbers together. But even before relating the Flood account, the Bible mentions forgers of copper and iron tools. (Genesis 4:22) In any case, to this day wooden drive pins known as treenails are used to build some wooden ships.

    The ark had internal compartments, a door in its side, and a one-cubit-high tso′har, which may have been a gabled roof, possibly having openings below it for ventilation and light. The Genesis account makes no mention, however, of a keel or a prow or of any sails, oars, or rudders on the ark. In fact, the same Hebrew word for “ark” is used to describe the pitch-covered basket used by the mother of the infant Moses to keep him afloat in the waters of the Nile River.—Exodus 2:3, 10.

    Good Seakeeping

    The ark’s length was six times its width and ten times its height. Many modern ships have similar proportions, although for them the length-to-breadth ratio is chosen with regard to the power required to move them through the water. The ark, on the other hand, had only to float. How well would it have performed?

    The manner in which vessels respond to wind and waves is called seakeeping behavior. This too is related to a vessel’s proportions. The Bible describes the tremendous downpour that produced the Flood and also says that God later caused a wind to blow. (Genesis 7:11, 12, 17-20; 8:1) The Scriptures do not say how strong the waves and wind were, but likely both wind and waves would have been powerful and changeable, even as they can be today. The longer and harder the wind blows, the higher and farther apart are the waves. In addition, any seismic action could have produced strong waves.

    The ark’s proportions contributed to its stability, preventing it from capsizing. The ark was also designed to deal with the forces that could cause it to pitch lengthwise in heavy seas. Extreme pitching—when each wave lifts one end of the vessel and then allows it to plunge downward—would have been very uncomfortable for the people and animals on board. Pitching also puts heavy stresses on a vessel. The structure must be strong enough to resist the tendency to sag in the middle when large waves lift both ends of the vessel at the same time. Yet, when a large wave lifts the vessel at its midpoint, with nothing to support its ends, the bow and stern may bend downward. God told Noah to use a length-to-depth ratio of 10 to 1. Later shipbuilders would learn only by hard experience that such a ratio can accommodate these stresses.

    Oh dear - you have been sold a strange idea.

    NA he might have been, but there is no 'optimum' beam, height, length ratio for all boats , and a little bit of research will tell you that it 'depends' on so much, including materials and cargo.

    eg http://en.wikipedia.org/wiki/Beam_(nautical)

    It wouldn't be the first time a professional has presented a lot of fact, with hidden inaccurate info to make a religious point.


    Regarding caravan/floating things, search for 'ark' on these forums for a start, then amphibian, then raft etc.

    Over the years, I have seen dozens of versions of floating caravans, wheeled boats and everything in between. If someone with so little marine experience has come up with a leading concept, I will accept it as a divine miracle.

    Well, I'm not a naval architect or any other sort of architect, but I have no hesitation in saying that the information below is complete and utter rubbish. It in no way is an accurate statement about vessels of any description. Even I know that, and I'm just an ignorant retiree.

    Leaving aside the minor detail that nobody has ever laid eyes, let alone a tape measure, on Noah's Ark in the first place.

    So - if you're basing your idea on anything like this, stop now and save everyone a lot of pain.

    Why do I think this is just another troll???? Fair warning, I'm only going to add to this thread with the aim of ridicule from now on, absent some actual *facts*.
