    Hi,
    I would like to use as a keels in motorsailer profile NACA 664-0, but I can not find the net just for this profile (in any generator profiles is does not this type). Can You help me, pls?.
    Best regards

    The NACA 4-digit profile generator will give you an adequate profile see http://www.ppart.de/aerodynamics/profiles/NACA4.html which will come up as NACA0012, just change the last 2 digits to the % thickness you want. It has a lot better lift/drag than a flat board and is not much inferior to the profiles used by serious devotees of performance. For a motorsailer delaying onset of separation is much more important than minimising drag.
