    When I looked at the SWATH configuration I didn't considerer it further because the amas would be deeper than the center hull blocking a great portion of the view to get a fair enougth view they would have to be as far as possible from the center hull (encreasing. Beam way out of proportion )that is why I think that a moving center hull that could be lowered and raised by means of hydraulics will work better using the mass of the amas filled with water as ballast to push down the center hull.

    Thanks for that - I missed some of the early posts. Kinda disappointing, I thought this guy was for real.

    Yes it can be and has been done. Ten points for you. :cool:
    Cheers.

    Don't be disappointed. Look I started with this Idea of mine with a capital 25000$ this is what I got at hand without pulling money out of my bussines or my retirement fund or yes I have to admit it without making the wife go crazy.Let's call it my play money. That doesn't mean that if after researching the project enought and find it viable that financing could not come from some where else like a partnership, bank loan or sponsor by a fundation, university or what the heck a local Beer company
    So again don't be disappointed (notice I didn't say "sorry" to disappoint you) if more money is required I got ways to get it.
    Buying an already built semisumersible is an option but my project is to build one myself for less money that I can buy one use my whits and everyone else who will be willing get envolve to sort out all the technical problems that should arise and to do it in a practical simple way and of course under budget. There is more to it than just building this one boat Believe me !!

    That's makes a bit more sense. The engineering and hull design calcs, and certification fees alone would have eaten up most, if not all, of your initial budget.

    I didn't say your boat was ugly I said that I was told my boat would be ugly.
    But on the other hand your boats not real pretty either, at least at the moment, and that would probable effect revenue?
    Anyway I think it's a great project to do at the minimum cost your talking about.
    Your design is cheaper than my design if you want to get the eyeballs under the surface without going to any real depth; and I don't think there's anything wrong with that.
    It would probable be cheaper as a single wide hull with a narrow viewing chamber under the hull.
    But for fast passage as well as docking that becomes a problem.
    You might consider a somewhat flat and wide mono hull with a boxed in opening in the middle and for most of it's length and an open topped viewing chamber (fitted into this opening) that could be raised and lowered from flush with the bottom of the hull to 6 ft. down? There would be a problem with getting passengers over the box and down or up into the viewing chamber without wasting too much space?
    I still think my design; modified to short pistons (maybe 8 ft. stroke) between cat hulls with ballast tanks (in the bottom of the hulls) that are self pumping using the 2 pistons and the buoyancy of the passenger is better than a cat with large windows built into the hulls plus pumps and overhead tanks? On the other hand I would require a third passenger hull. But simpler outer hulls built for good performance with room for separate engines and fuel plus the sealed air chambers at the top of the hulls for safety (unsinkable and uncapsizeable).
    I think there are pros and cons with either design?
    The attached is a basic hull section containing an air chamber, a water chamber, fill/drain valve and air vent.

    Ballasted Hull

    Either for a trimaran with center hull or for each amas on a catamaran this is what I ve being thinking

    The other problem?
    My hulls are made up of separate chambers like the Titanic but better.
    1 valve per section maybe 6 sections per hull and sealed air chambers in the TOP of each section; It all becomes a part of the necessary structure to build the hulls in the first place.
    I would not want hulls that were open from one end to the other. The cost of insurance is also important. I think it might be hard enough getting a new design insured especially if it does not look completely safe?
    In the tri design the passenger hull is protected by the outer hulls.
