    Does anyone know of, or recommend, software that plots Bonjean curves and the complete curves of form ("curves of displacement and other curves") of a particular hull? Ideally, one that extracts data directly from a model, but if not, one based on direct numerical input? Please see attachment.

    thanks kindly,

    Stephen,

    Curves of form? First time seen one...

    I'd reccomend you to model it in rhino :/ it doesn't have the sophisticated stuff you mentioned, but you can easily model ANY hull shape instead ;).

    Regards,

    Kuba

    Any marine design package should have the ability to ouput hydrostatic properties (which is what you are looking for).

    AutoShip / AutoHydro, Multisurf are two. Or a stability program such as GHS will do the same.

    yes

    You can do as it is in ur pdf ,, using Archimedes Mb , or Hydromax , or Autohydro , etc

    if u use rhino then using Rhinomarine or Orca3d you can do that easily.
    some of their demo version is available , so you can try ...
    thanks

    Thanks Kuba, Henry, and zeroname for your replies.

    To give you a little background, I have nine graduate students building models of nine related hulls, and I want to do a thorough analysis of the differences between them. We are modeling in either Rhino or Maxsurf. It looked to me that in Orca 3D and Maxsurf you could easily get hydrostatic and form parameters, but only at one waterline. To generate the curves, of course, you need to iterate and generate the data at, say, 10-12 drafts, and then plot it. I do have the whole professional maxsurf package (just learning it) and I see now that you can indeed do this in Hydromax (thank you for that zeroname).

    Having only the Maxsurf package and no experience with the others you mention (Autoship, Autohydro, Multisurf, Archimedes Mb), can you tell me if there is much difference one from the other, or one that is much easier to use or more capable for this particular purpose?

    thanks again for your advice,

    Stephen

    the results vary not very much, but i feel its convenient to do the calculation with the software package, as if u model in maxsurf use hydromax for the best result,
    to use software , it depends on the user which one he feel easier than others. for me if i use rhino , then orca3d is easy or then the hydromax ,

    you can try demo before buy to know which suits best for u,

    As the others have mentioned, Hydromax will let you do this pretty easily using the Upright Hydrostatics analysis option.
    We have lots of schools using Maxsurf and Hydromax for teaching naval architecture so you should be on safe ground there. If you need extra help, feel free to post here or to contact us directly at support@formsys.com.
    PS Also don't forget the navarch teaching resources on our academic web site at msacademic.formsys.com

    thanks kindly formsys.

    Yes, hydromax looks like it will do exactly what we need, and I will indeed look at the academic website, and be in touch.

    Thanks kindly,
