    You will have to be more specific. You didn't give enough information to make a good estimate.

    Give weight, draft, LWL, hull beam and profile, overall beam etc.

    The free program "Michlet" can give reasonable estimates for catamarans if
    you have the principal dimensions and offsets of the demihulls.

    thanks for the responds from both of you...i have a hydrostatic data from maxsurf, and i've already running from hullspeed using savitsky.but i still want to know the manual calculation for total resistant and power estimation for this catamaran.
    below is my hydrostatic data.
