This skin is great.

It even has a decent view from inside the flak-turrets.
I know the coloursheme is hardly historical (compared to Fubart's Dunkelgrau51), but taking this boat out to war is pretty fictional anyway...so I go with this beautifull matt-black:
@GWX-devs: I was able to clock a submerged topspeed of 21kts (!), using the Schnorkel...
Allthough I read, that it could travel submerged at nearly 18kts for a short period of time.
And one other thing: the RDF-loop isn't raised together with the radar-antenna (see image)...at least, not on that game-load. The 1st time I loaded this boat, it was working, but while using Fubar's skin.
Could it be due to this custom-skin, which was made by changing some .dat-files?
