Dang!.. that’s what I thought… sigh
Oh yeah we are aware about the size in fact that’s the idea… we want a HUGE diorama for displaying at our local modeler club down here. The idea is that everyone at our club to participate in a communal build, and we thought about this cargo or merchant ship in the dock getting filled with a couple of tanks some disambled airplanes, jeeps etc, and in land some other staff cars parked around, full of busy people, in short, tanks, airplanes, ships, figures, etc, everyone subject and technique, at least that’s the idea so far.
Just as you said it will be a looooooong term project, but at least it will keep us planning arguing and building all together for some time. 
The irony of the project it’s that the main subject will be the ship and at our local club the majority build airplanes and tanks, just 2 guys build ships, battleships specifically, and when we wondered what kind of cargo or merchant ship would be ideal, well… we found out that our knowledge about merchant and cargo ships are quite limited… 
We are thinking about some Victory-class or Liberty since they were the more common, but some (including me) think about something not that common like some german or italian cargo ship, delivering tanks and airplane parts to, say, Northafrika, or some japanese, the question is, it was some axis cargo or merchant ship capable to get loaded with both tanks and airplanes?
Thank you EdGrune, for the page floatingdrydock.com, I’m on it right now.
