    There was never a lynchmob around here, nor any bets on Ellmers life!

    Stop talking such nonsense Steve!

    But when one makes big statements here, trying to sell his crap, he at least must be willing to answer some polite, serious and basic questions!

    There have been at least two dozens of polite attempts to get a reply on the questions: where are the data sheets? Who has proven them as stated here 25 times? Which sort of concrete was used? How was it poured?

    Only mad drivel was the answer!

    In a life encounter I would have cut his throat already when that happened the second time!
    Then you could have used such term as "lynchmob"

    And to your Submarine project:

    The experts (on concrete AND submarines), are in consensus that it IS possible, but not sensible to build a sub in concrete.

    I completely missunderstood you.

    If you just want to have fun, this is the thread for you:

    I keep up with that one too, Tom. Overall, I think I enjoy it more than the Boat Jokes thread.

    20 Ton Concrete Sub specs

    I have been following this thread for sometime as the concept of a concrete sub interests me. I agree with most though that questions need to be answered. I did some digging around and found little information about Willy's 20 ton C-Sub from Austria back in 1996. Being a novice but assuming Willy apply's the same building techniques for the 200 tonner as he did for his smaller C-Sub maybe the following might answer a few basic questions:

    Austrian Concrete Submarine
    Here's a impressive, and exciting submarine project. Well, it's exciting if you're interested in building pressure vessels with concrete. Now that's an obscure branch of nerd...

    Back in 1996, Wilfried Ellmer built, tested and used a 20 ton concrete submarine on an Alpine lake. Residents of Lake Atter in Austria witnessed the launch of a pristine, streamlined, white vessel. The photo at right shows the boat at launching before the fitting out of sail, rudders and propellers.

    Wilfried states that the 18cm (7 inches) thick hull gives an operational depth of 300m (~1000ft) and an estimated crush depth of about 900m. He used portland cement reinforced with 4mm and 6mm steel in a 10 cm mesh.

    This is a large personal submarine, weighing in a 14 tons before ballasting. Check out the interior photo on the website which shows a roomy cabin. Unfortunately missing are any photos of the sub actually diving or even maneuvering on the surface under its own power.

    Yea we have all read this also. It seems Mr Ellmer never actually dived the boat. He just float tested it and then it dissappeared.

    Much like his present claims he gets close to showing some proof but never quiet makes it to actual documentation.

    Yes it does answer the most basic question:

    -Is the designer providing performance specifications which are totally unsupported by any testing?-

    The answer: Yes he is.

    As has been stated in this thread many many many times.

    seems to me if it did work, that the man hours of maintenance and inspection would leave you little time to enjoy sailing the dam thing

    i was in military aviation maintenance and and maintenance and inspection on a man hour basis was many times more than the flying hours

    we're not talking about something that if it went south you could jump in a lifeboat or call for a tow

    this in my opinion ranks right up there with the flying car and alien abduction

    nature always finds the hidden flaw

    Wardd my friend,
    I ave seen quite recently there are so named airplanes (objects heavier than air) flying!!
    Although my credibility here is not quite high, you MUST believe me in this case,
    they are concrete!!!!!!
    I was not allowed to touch them so I cannot comment on the material. If you are in a urgent need of info, I can try to get a sample cut of the so callled "hull"

    All my best for today

    You visit every day but say nothing...

    Will there be no crush test?

    No bet from you on how many meters your wonder-boat will withstand?

    Are you truly a coward, all talk, no substance, a dreamer?

    What happened to the big shot who had it all figured out.


    What's your crush depth estimate?

    I guess there wont be one now will there. Of course not.

    Rest In Peace Willy.

    Dear Sirs,

    My name is Henrik Kindblom and I am the managing director of European Submarine Structures AB in Stockholm.

    A lot of concerns have been expressed about our submarine project and I would like to adress them.

    The hull

    I have been in Cartagena, Colombia, and seen the hull from both the inside and the outside. During my visited I inspected the hull and I could see that it was well built and that the quality was high.


    The safey of our submarines is of outmost importance. Before European Submarine Structures starts to sell submarine hulls the concept will be carefully tested. This includes test of crush depth and cyclical loads. We won't sell any concrete submarines before we know that they are absolutely safe. Highly qualified swedish engineers will double check all calculations before any submarines are sold.


    We had some initial problems with moving Ian's submarine. Some of our equipment broke down. However, these problems now have been solved, and the submarine is slowley making its way towards the water front.


    Being a Swedish-Colombian company we are very well aware of the severe problems that the drug trade causes the Colombian people. Due to this we consider the drug trade as a "crime against mankind".


    I read all comments about the submarine project on this forum. The positive as well as the negative ones.

    Best regards,

    Thank you, HK for the input. What kind of tools did you use during your inspection? Did propeller look as though it had been installed properly? How thick are the glass portholes? Did you see any rust? What was the hull painted with? Are through hull fittings to rudder controls and prop shaft sound? Did you take any radiographs of the hull or ultrasound same? Is the propeller made of concrete as has been alleged, or is it possibly papier mache made from Colombian newsprint?

    HK, I just visited your web-site and saw the beautiful submarine hotel accomodations you offer.
    I would be more inclined to stay in an underwater suite that is firmly anchored than I would to ride a concrete sub over the edge of the continental shelf towards certain oblivion.
    Underwater room; good. Underwater room filling with water sinking out of sight; bad.
