    I just started to use Free!SHIP.
    I have a question now why I can't calculate GM'(transverse direction).
    After calculation, Free!SHIP indicates (-) number.

    Will you teach me?

    I think there are few options to analyze:
    - you have placed a KG too high.
    - The program places, by default, the c of g. in the wrong position
    - metacentre calculation is not correct (this seems less likely)
    - the hull is not stable, and you have to design a better one.
    Checks, first, the position of the center of gravity. In general, it is easier for the user to do wrong tan for the program.

    Thank you!

    Thank you !TANSL
    ;)

    I forgot to explain detail.

    I could calculate about monohull, not about Catamaran!

    In case of Catamaran, will you teach me ?

    I do not know FREEship, so I can not solve specific problems with this program. I use other programs and I have knowledge of naval architecture so in that field, probably. I could help you (monohull or multihull) ..
