    Yes, the modelling code and the GUI are essentially the same for Delftship and Freeship Plus. There is no guarantee of file compatibility between the native file formats of the two programs, though.

    You can take the guarantee out :D The files are not interchangeable. On my PC anyway, I had to redraw my boat's hull from scratch.

    I was joking, but I meant the river Nile.

    Thanks Matt and Fanie.
    I suppose you have some import/export also?

    Today I revisited the Polycad web pages.
    It looks quite impressive, but when I tried it some years ago I found it not so user friendly. Maybe I'm getting old, I grew up with AutoCAD (from 1986) and I like the way Rhino work as the "3D Surface AutoCAD" we all wished for.

    Thanks Marsh, but I couldn't find any info about power/resistance prediction methods available. If you or someone else here uses DS, could you please give me some info? Thanks.

    Very cool graphics, but is it realistic?

    I think it's a pitty that such a nice software has only two resistance predictions available - and none for planing hulls, for example. I wrote that to Martijn a year or more ago, and have hoped to hear that something has changed in the meanwhile... :(

    By the way, for anyone who is interested I came up with a trick to get smooth lines plans out of Delftship. I imagine it would be as good with any other software that produces lines plans.

    As an old(ish) fart who grew up with manual drafting I've always found the jaggy lines outputted from CAD apps rather annoying.

    The trick is to export that lines plan at a ridiculous size (20,000px wide works well) and then use a graphics app like Photoshop or GIMP to shrink the image down to a handy width (like 1280 or whatever). The shrinking process smooths out the jags so that the result is very nearly as smooth as traditional manual drafting. Save as a jpg and it's all sorted.

    I don't know if this trick is original but it works and it works well. :)
