    Hi,

    I was wondering if there is a (empirical) formula to estimate the resistance curve for other drafts based on a known curve for a certain draft? I don't think you have this for a complicated hull form, but surely someone has ever investigate this for a 'standard' hull form?

    Method

    Dear,

    Except that suggested from jehardiman.....

    Try in FreeShip software to take the hull form you like from the examples files and to increase by step the drafts .
    then you calculate for each of them the resistance and you take an Idea about that you asked.
