Alex, I will post some photos, although I am not as talented as you. I do have the 'sliding' hatch, it is convenient, although I need to repair the top piece as it is cracked, these little things that still remain after one and a half seasons. Also, the mast and boom is Dehler, I think that is about the last year they stopped doing the rig.
I have sailed a JV designed Dehler 36, a very nice boat, I really liked the ergonomics, if you know what I mean, things were just 'right". I really like the 39 too, maybe after I get bored with the 33!
When looking, I wanted something different, i did not want a J or Bene, etc., but also something we both could enjoy. The boat has a full interior, with standing headroom in the head (a requirement) and a comfortable cockpit with high seatbacks, and with the traveller behind the tiller and primaries on the coachroof (something I was not sure about but it is ok), it is open and not cramped, especially with the stern locker removed.
