    LCF is just the centroid of the waterplane area, and on that sort of hullform it's not a complex shape. You can approximate it reasonably with 3 or four trapezia. You should be able to reduce the full set of equations to a single line.

    The problem is that i am constructing a prog, where it calculates several things, I assume that the user knows only some basic ship particulars L, B, T, D, Cb etc,

    Many thanks for your reply

    It is not unusual to ask for LCF in input data (for example, as a percentage of some particular length).
