Did some work on U-93 after getting home late...
The conning tower shape will be changed slightly to taper more towards the back. Torpedo tubes & net cutter will be added later. It's easier to texture the hull, then add torpedo tubes, than to do it the other way around. I practiced texturing the bow several days ago - results were very encouraging.
These were very pretty boats IMHO and effective war machines. Too bad you won't be getting your hands on one of them until 1917, when the war's practically lost.
