Hi Maarten,
That's good. I also like building my own yacht, I think that is better than buying one.
At the Eindhoven University of Technology we got the study association of Mechanical Engineering, called W.S.V. Simon Stevin. Since I am still studying, I am a member of that study association. For over 40 years now they are building their own land yachts and take them to the beach, mostly at IJmuiden (the Netherlands) or de Panne (Belgium) to go for sailing a couple of times a year. There I had my first experience with building in land yachts.
Now, I am building my own class 5 land yacht at the workshop of the study association, with a lot of help from this forum. (You can see my progression at
www.seabreeze.com.au/forums/Land-Yacht-Sailing/Construction/Designing-class-5-yacht/). I am not fully finished with it and at the moment I am on an internship in Singapore, so for the next 2,5 months I cannot complete it. But when I get back, I will finish it, test it and hopefully enjoy it for a lot of time.
At the end of the topic of my land yacht, you see a photo with the sail in it. I have had the sail made at Scaldis Sails (
http://www.scaldissails.nl/) and I think they did a good job. You could have a look there for your sail as well. They made some sails for some yachts of the study association as well and we think that they do a good job. They also make sails for blokarts, so surely they did some more jobs on sails for land yachts.
