Latest news

Unfortunately, a Dutch payed online platform for administrating Saling Regattas, has been forced to cease all activities as of now. The Corona crisis was fatal for their continuity.

Since ZW has no business model, we will continue as before. The Corona crisis has affected me also in that my priorities shifted, like everyone else’s.

But work hasn’t stopped and I hope that as soon as Sailing commences you can enjoy the new ZW.

Everybody stay safe!

The finish is in sight

Dear ZW users, thanks for your patience! And thanks for the ZW-files I received!

The rebuilding of ZW is nearing its end, I really hope to get a beta test out in four to six weeks. But, as I learned, things that look simple sometimes are exactly the opposite and take much more time than I expected. I can honestly say that in my 30+ year as IT-professional I have never had a challenge quite like this one. Needless to say I learned a lot.

In this first roll-out I mainly focus on getting scores in, correct results out and managing those in several ways. But that leaves many things to do, like almost all stuff that is related to Regatta management, for example Protests and Licences. Also all lists, besides the results, still need to be addressed. After the beta is out I will focus on creating all the remaining lists and working on the IMS/ORC options and the ISAF XRR export. Priorities will be based on the reactions I get for realizing all of these.

Anyway, first thing now is getting the beta out and fixing the issues that come out of the tests. Working very hard on it every moment I get.

Please bear with me a little longer.


Testing ZW 5

Since testing of all the possibilities of the ZW calculating machine turns out to be a very big task, I would like to ask you for a little help.

My intention is to build a large test-suite of many regattas that I can run and recalculate automatically overnight. That way I can be sure that all calculations will remain correct over time. Or that I need to do some more work.

So, please send me your *.zw files that I can use to this end. Doesn’t matter how old or how big. But preferably regattas with handicaps in them. Or other specials that you can think of.

You can mail them to zwscoring(at), preferably with a short description indicating what I should pay attention to for your event. I can’t guarantee I’ll reply to your mail, but your effort is always appreciated.



Ps (at) is @ of course 😄

Summer break is over

This weekend I started working again on ZW 5 with fresh enthousiasm!

I left off a few months ago when I was working on the subfields. Got stuck a bit then, which bugged me a little all summer, but this weekend I made great progress. Almost done, finishing up some loose ends and still some testing to do. Next sub-project is entering finish scores.

To be honest, when I started this I didn’t think it would take me (at least) two winters to rebuild this amazing program. That was a bit naive, but had I known I still would have done it. It’s a great challenge. All the more respect for what Leo created.

So, thanks for your patience. I will try to post an update every now and then. In the meanwhile I’m working hard to get a beta version out somewhere in the next half year. No promises 😄

Progress update

Since Visual Studio 2019 came out last week, I will be converting from VS 2017 soon, to keep up with the latest technologies.
In the meanwhile, ZW 5.0 now calculates and prints correctly for fields and subfields.

Only a few more forms and lists need to be done, but experience from the past year tells me that it will still take some time before I can start rolling out.

So please be patient a little longer, I’m working as hard as I can to get a new version to you as soon as possible.
