    Peter,

    What do you need to do with your offsets? Are you looking for something that can do hydrostatic calculations, or something that'll turn your offsets into a surface model, or just something that'll give you a nicely formatted table?

    For which result Peter? To import them into a CAD machine or what?

    ahh, thanks Matt! (one shall not open a thread and reply half a hour later)

    Peter,

    Can you send (email) me the offsets? In a scanned table or XCell spreadsheet or whatever....

    see if we can get a hull out it....

    The easiest way I am aware of would be then to type the offsets in a excel sheet and import them into Freeship or Delftship.

    The Freeship tutorial whcihc comes with the freeware, handles the "howto".

    (I assume you have freeship)

    Regards
    Richard

    So here's the wire frame, ends still don't quite make sense....funky sections aft around the prop opening....trying to reconcile the sections and the profile doesn't seem to quite work.....

    This is with stations and waterlines at 500mm spacing...
