    DEAR FRIENDS
    I 'm going to find a good body lines (hull) for a flat barge which i know it's principal dimension.
    how can i start?

    Well................ I'd start with a rectangle to scale with the principle dimensions, this will be a good start as barges are constant in section for much of thier length, the bow and stern are modified with a swim end or cutaway depending on the use & propulsion, variations can see facets or radius to lower chine/corner for smoother water flow.

    can i get a correct result by estimation of water resistant using "MAXSURF HULL SPEED" software?

    That's some question your asking.................. I don't know what kind of result MHS will give you, probably a fair estimation if the input data is better than estimated, did you find your good body plan yet... 'cos that's where you started?

    Maxsurf Hullspeed does not use its own empirical methods to estimate the power but universally recognized methods, as Holtrop-Mennen. So while these methods are considered reliable, and properly used, MaxSurf results will be very good.

    Does it include empirical methods specifically for barges?
    Or only for more ship-like forms?

    We still do not know the shapes of the barge. As you perfectly know a barge can have ship-like forms.
    You certainly know the method as well as me. But, answering your question, I donĀ“t see in the description of the method specific reference to the barges. According to the authors of the method "extension of the method was focussed on improving the power prediction of high-block ships with low L/B-ratios and of slender naval ships with a complex appendage arrangement and immersed transom sterns."
