wow. you captured the spirit of the Type II very well, except some quesions:
-Why is the hull mosly red? the ballast tanks aren't supposed to be under water.
-The boat needs to have its length increased by about 20%.
-wrap tan masking tape around the winter garden (railing at back of conning tower) because most Type IIs had a canvas cover there.
-why does the deck gun have a rail all the way around it?
Nice job though. Two thumbs up!
