Here the GPL is a tool to allow effective collaboration and more efficient development of code. Companies that buy servers recognize that the developers who put millions of dollars and thousands of hours into server Linux work deserve to be paid for it, and that if they weren't paid the code would not exist. This is perfectly acceptable and common practice, as is charging money for open-source code. Indeed, a key component of the preprocessor for the $20,000 Fluent CFD suite is under the GNU LGPL licence. Good luck with the project, Martjin all the best and I hope it works out for you.Ĭlick to expand.The GNU GPL does not prohibit closed-source developments from being based on open-source code. I may end up staying with 2.6 as, without IGES support and with limited stability-calculation power, DelftShip Free is much less useful for me.

Granted, the sale of only one or two full suites a month would go a long way, but it'll be hard convincing professional designers to invest that kind of money in a program when there are other, more widespread options that may be considered safer buys.

I'm not sure whether DelftShip Pro will be able to make many inroads here.
which are widely used in industry and are very powerful general CAD programs as well. In this range there is direct competition from big names like MaxSurf, Rhino (with rhinomarine), etc. DelftShip Pro starts at 150 euro (~$180 CDN) and the full suite is, if I read the table correctly, 1950 euro (over $3,000 CDN).

FreeShip was by a very long shot the best free/low-cost marine CAD software out there and seemed to be developing a very big user base (especially on this forum) it pretty much took the community by storm with the 2.x versions and is loved by many an amateur.
I'm curious how the pricing structure will work out. I would have thought that the new free version would be at least comparable to the old, with the Pro version containing all the new, specialized code. On the other hand, as far as I can tell the "Free" version is actually less powerful than Freeship 2.6- IGES support is gone, as are some calculations such as basic crosscurves. Server space is expensive, and given how much time Martijn must be putting into this, he certainly deserves something for that! So I'm not at all opposed to a paid "Pro" version with more features. It'll be interesting to see how the project plays out now that new versions are not freeware anymore. It looks nice and seems to function efficiently, for sure. Well, I still have some experimenting with the new version to do before I can draw too many conclusions.
