    Hello there,
    I would be interested to know what kind of engineering complexity is involved in order to improve vessel performance at given cruising speed of a catamaran existing design by adding of a central foil (new design project) between the hulls,( guess near the Center of Volume/Gravity).
    Now a day, by updated sofware, would be this easily feasible for an expert of the sector to design the proper NACA foil.
    I would like to understand in general whether this is throughout easy possible or what I should be aware of.
    Appreciate your kind attention

    You will need to give more details to attract useful responses. You have mentioned little of your proposed "e-catamaran", and probably need to define what that term refers to.

    Let me clarify that a NACA type profile cannot be designed. They are all already "designed", you just have to choose the profile that is most suitable for your purposes.
    On the other hand, no software, no matter how updated it is, will allow you to carry out this transformation if you do not have the required technical knowledge. The disciplines that come into play (perhaps I forgot some) for this project are naval architecture, structural calculation, hydrodynamics and knowledge of composite materials and their uses.
    As for the complexity you ask about, "what kind of engineering complexity is involved", it depends on your knowledge of the aforementioned disciplines.

    There are several examples of hybrid planing/foiling catamarans around, do a search for "hysucat" for instance. As TANSL has mentioned, a thorough understanding of first principles of physics is required, as expressed in the various disciplines involved. For you it's time for studies........!
