Hi!
Me too looking forward to see this one being build!
Very promising start! And nice size!
I have myself some FLY MODEL kits in my brother's cellar (ships, planes..). As far as I know in Poland there are no waterline models. No offend, but they are seen (or were seen) as something "half done" or a "not good model" at all. I can remember how my brother and me were laughing at the waterline ships some 20 years ago. But of course we were children and today I appreciate them as well as full hull models. Especially when they are placed in a diorama like Lars his research Ship "Planet" (sehr schön gelungen, Lars!!) or if they are made as this kind of "hybrid" where one can separate or attach the lower part of the hull.
There should be no problem if you attach the hull first. Generally you can fit the rest of the model to the hull and not the other way around.
I don't know if the model description is only in polish language or not but If you need some help in translating it, I can help you Marco!
Regards,
Radek
