Ok, cool :)

We'll have to see if anyone's built one, I really don't remember.

Both designers are well thought of though, I've built one of Rob Mack's boats, the Disko Bay and am starting another and used some of Vaclav's techniques, both do a nice job on their designs from what I've seen. They are very different boats, I'd pick the one you like the best :)
