    Any 'big size' inflatable catamaran available or what are design characteristics to be considered in making one ?

    I like the idea! Go get two of those inflatable kayak-canoe like things, make a fold-able frame that holds it all together, with a sail board or hobie cat sail, and you got a 2-person plus catamaran that will store in a closet! Should not cost too much to make either. You could get by with a single rudder and center board on your frame (keep it simple!).

    once you get it all together, post pictures of it for us.

    Take a look here, up to 28ft but this company will make just about anything, and they do very nice work.

    Take a look here. This guy did an outstanding job of using 2 canoes as a sailing catamaran.

    A very nicely engineered vessel that seems to have excellent sailing characteristics. Throughout the video it appears as if the vessel is sailing with the tiller lashed.

    I admit banana tubes look quite ad hoc , but they are preatty expensive aren't they ?
    What puzzles me more is the solid structure and inflatable/structure joints.

    Inflating or pressurizing a hull makes it stiffer without adding much weight. But it also tends to make the enclosed area unusable for other purposes.
