Find the waterline

Will one of these freeware programs be able to find the waterline of a 24' boat if I have all the lines and weights? thanks:Or is there any easy way to find the loaded waterline if I have all the lines:?:

 

I think they should. Inputing lines, just run the hydros and search within them for a displacement equal to the sume of known weights (I'm asuming 0 trim). If you know the longitudinal position of all COGs for all weights with precision, you can even find the proper trim by running hydros for several trims and find which one provides the center of buoyancy with the same X than the COG. if trim is small we can asume this as being true (If the program uses a fixed to the boat reference system -most NA programs work like this- when B is right in the same vertical as G they do not have exactly the same X).
Cheers.
