Hi
Thanks for the uboat.net URLs, altough i know the site, i didn't know those particular urls, and i think i can adapt some models to look like some of those ships.
Regarding coastal boats, we'll get there eventually, i already gathered some data
That's pretty much it, as you mentioned, blueprints are hard to come by, if anyone finds any blueprints/schematics of civilian pre-ww2 and ww2 era ships, that would be a great help (it's hard to extrapolate into actual geometry a couple of photos, and even with tons of photos as reference, schematics always help sorting out the details).
That's pretty much it, stay tuned
