    Thick enough and big enough to carry your anticipated loads. But not so big as to be too heavy.

    Solved.

    Next question?

    Seriously, maybe you thought you were asking a simple question. You were not. A little more definition, no, a LOT more definition would be required.

    I don't think you understand that your question does not have a simple answer. The hull and associated structural members of a boat is more complicated then "xxx" thickness.

    Really...
    Tell me and I forget. Teach me and I remember. Involve me and I learn.
